Transplantation of Wince 6.0 BSP (1)

Reprinted please indicate the source

Author: Pony

A project of the company should be implemented based on ce6.0, but the number of boards on hand is 5.0. I wanted to save time and ask the manufacturer for a 6.0 BSP of the Board, I contacted their customer service and said that I was self-reliant because I didn't have the 6.0 BSP on this board.

 

At the time of writing this article, the oal part has been transplanted successfully. According to the dnw output, the system has started successfully. the rest is the peripheral driver part. I don't want to port all the drivers, because my goal is to do upper-layer applications. This upper-layer application will use some hardware resources, such as serial ports, LCD, etc. Which peripheral is used to transplant the driver. this can be completed quickly.

 

I didn't port bootloader because I used ads to develop a loader independently. It has eboot and nboot functions and does not use wince eboot. therefore, you can remove the bootloader directory under yourbspname/src, because it is not used. in addition, I would like to thank yashi and gooogleman on csdn for their answers to some of their questions on the Forum, which is very useful.

 

Let's talk about my method first. clone a 6.0 built-in BSP and use deviceemulator, because it is based on the 2410 cpu bsp, which is the closest to my board. next, compare the BSP of 5.0 and port it a little bit. It should be noted that I did not directly replace the oal-related files and directories of 5.0 with 6.0, instead, modify the source code of oal directly in the BSP of clone 6.0 without changing the original directory structure and file name of 6.0. although tedious, the BSP obtained in this way is more standard. it is recommended that Microsoft retain its original directory structure when porting to 6.0.

 

The procedure is as follows:

 

1 clone BSP

Open vs2005-tools-pfatform builder for CE 6.0-clone BSP.

Select deviceemulator for the clone source, and name your BSP my2410.

 

2. Create an operating system project

Use my2410 bps to create an operating system project. To facilitate oal debugging, you can create a simple system. You can select Custom when customizing the system, and then click Finish. after the LCD driver is transplanted, a shell system can be customized. After all, it is very exciting to see the interface.

 

3 startup code

Find the startup. s file (my2410/src/oal/oallib/ARM)

Change the value of sleepdata_base_physical to the following:

SLEEPDATA_BASE_PHYSICAL         EQU     0x30058000

 

Find the following two lines

If software Reset

MoV R1, #0

Change

MoV RR1, #0x38000000

 

To the cpupoweroff. s file (my2410/src/oal/oallib)

Change the value of sleepdata_base_virtual to the following:

Sleepdata_base_virtual equ 0xac058000

 

Find the cpupowerreset function. Replace it with the function in BSP of 5.0 as follows:

Change leaf_entry cpupowerreset to the following (replace with 5.0 BSP)

Replace the physicalstart function (the implementation of this function is omitted)

 

ldr     r3, =SLEEPDATA_BASE_VIRTUAL     ; base of Sleep mode storagemov     r2, #0x38000000             ; store Virtual return addressstr     r2, [r3], #4; Disable MMUldr r2, = PhysicalStartldr     r3, = (0x8C000000 - 0x30000000)sub     r2, r2, r3mov     r1, #0x0070             ; Disable MMUmcr     p15, 0, r1, c1, c0, 0nopmov     pc, r2                  ; Jump to PStartnop 

Find the implementation of the cpupoweroff function and find the following sentence:

Change LDR R6, = 0x88000000:

LDR R6, = 0x92000000

 

4. debug serial port transplantation.

Clone my2410 BSP uses uart1 as the debugging serial port by default, and changes it to uart0

First, find the oeminitdebugserial function (my2410/src/oal/oallib/debug. c) and run the following code:

CLRREG32(&pIOPortReg->GPHCON, (3 << 8)|(3 << 10));SETREG32(&pIOPortReg->GPHCON, (2 << 8)|(2 << 10));SETREG32(&pIOPortReg->GPHUP, (1 << 4)|(1 << 5));g_pUARTReg = (S3C2410X_UART_REG *)OALPAtoVA(S3C2410X_BASE_REG_PA_UART1, FALSE);OUTREG32(&g_pUARTReg->UFCON,  BSP_UART1_UFCON);OUTREG32(&g_pUARTReg->UMCON,  BSP_UART1_UMCON);OUTREG32(&g_pUARTReg->ULCON,  BSP_UART1_ULCON);OUTREG32(&g_pUARTReg->UCON,   BSP_UART1_UCON);OUTREG32(&g_pUARTReg->UBRDIV, BSP_UART1_UBRDIV);

 

Changed:

CLRREG32(&pIOPortReg->GPHCON, (3 << 4)|(3 << 6));SETREG32(&pIOPortReg->GPHCON, (2 << 4)|(2 << 6));SETREG32(&pIOPortReg->GPHUP, (1 << 2)|(1 << 3));g_pUARTReg = (S3C2410X_UART_REG *)OALPAtoVA(S3C2410X_BASE_REG_PA_UART0, FALSE); OUTREG32(&g_pUARTReg->UFCON,  BSP_UART0_UFCON);OUTREG32(&g_pUARTReg->UMCON,  BSP_UART0_UMCON);OUTREG32(&g_pUARTReg->ULCON,  BSP_UART0_ULCON);OUTREG32(&g_pUARTReg->UCON,   BSP_UART0_UCON);OUTREG32(&g_pUARTReg->UBRDIV, BSP_UART0_UBRDIV);

Modify the macro definition in bsp_cfg.h (my2410/src/INC ).

#define BSP_UART1_ULCON         0x03                // 8 bits, 1 stop, no parity#define BSP_UART1_UCON          0x0005              // pool mode, PCLK for UART#define BSP_UART1_UFCON         0x00                // disable FIFO#define BSP_UART1_UMCON         0x00                // disable auto flow control#define BSP_UART1_UBRDIV        (S3C2410X_PCLK/(38400*16) - 1)

 

Modify the values of the preceding five elements as follows:

#define BSP_UART0_ULCON         0x03                // 8 bits, 1 stop, no parity#define BSP_UART0_UCON          0x0245              // pool mode, PCLK for UART#define BSP_UART0_UFCON         0x00                // disable FIFO#define BSP_UART0_UMCON         0x00                // disable auto flow control#define BSP_UART0_UBRDIV        (S3C2410X_PCLK/(115200*16) - 1)

 

5 LCD Initialization

OAL's oeminit function will call the initdisplay function, so you need to follow your own LCD (my model is LTV350QV-F04, 320*240 tftscreen)

First, modify s3c2410x_ LCD .h (my2410/src/INC). The changes are as follows:

#define    LCD_XSIZE_TFT           (320)   #define    LCD_YSIZE_TFT           (240)#define    LCD_VBPD                ((8)&0xff)#define    LCD_VFPD                ((4)&0xff)#define    LCD_VSPW                ((4)&0x3f)#define    LCD_HBPD                ((13)&0x7f)#define    LCD_HFPD                ((4)&0xff)#define    LCD_HSPW                ((18)&0xff)#define     CLKVAL_TFT              (7)

 

It should be noted that the LCD is a slow display device and has high timing requirements. Therefore, you must set the equivalent of vbpd (related to the return time, the specific principle and how to set the parameters refer to my other article about LCD.

Http://blog.csdn.net/pony_maggie/archive/2010/01/29/5270147.aspx

 

In addition, modify it in initdisplay (my2410/src/oal/oallib/init. C:

Change the LCD _mval in s2410lcd-> lcdcon1 to LCD _mval_used.

Change s2410lcd-> lcdcon5 to the following settings.

S2410lcd-> rlcdcon5 = (0 <12) | 1 <11) | (1 <10) | (1 <9) | (1 <8) | (0 <7) | (0 <6) | (0 <5) | (0 <4) | (1 <3) | (0 <2) | (0 <1) | (1 <0 );

 

6. memory space configuration

The memory configuration includes the following parts:

Open the oemaddrtab_cfg.inc file (my2410/src/INC), and configure the g_oaladdresstable variable according to the following values:

DCD 0x80000000, 0x02000000, 30  ; 30 MB SROM(SRAM/ROM) BANK 0    DCD 0x82000000, 0x08000000, 32  ; 32 MB SROM(SRAM/ROM) BANK 1    DCD 0x84000000, 0x10000000, 32  ; 32 MB SROM(SRAM/ROM) BANK 2    DCD 0x86000000, 0x18000000, 32  ; 32 MB SROM(SRAM/ROM) BANK 3    DCD 0x88000000, 0x20000000, 32  ; 32 MB SROM(SRAM/ROM) BANK 4    DCD 0x8A000000, 0x28000000, 32  ; 32 MB SROM(SRAM/ROM) BANK 5    DCD 0x8C000000, 0x30000000, 64  ; 64 MB DRAM BANK 0,1    DCD 0x90800000, 0x48000000,  1  ; Memory control register    DCD 0x90900000, 0x49000000,  1  ; USB Host register    DCD 0x90A00000, 0x4A000000,  1  ; Interrupt Control register    DCD 0x90B00000, 0x4B000000,  1  ; DMA control register    DCD 0x90C00000, 0x4C000000,  1  ; Clock & Power register    DCD 0x90D00000, 0x4D000000,  1  ; LCD control register    DCD 0x90E00000, 0x4E000000,  1  ; NAND flash control register    DCD 0x91000000, 0x50000000,  1  ; UART control register    DCD 0x91100000, 0x51000000,  1  ; PWM timer register    DCD 0x91200000, 0x52000000,  1  ; USB device register    DCD 0x91300000, 0x53000000,  1  ; Watchdog Timer register    DCD 0x91400000, 0x54000000,  1  ; IIC control register    DCD 0x91500000, 0x55000000,  1  ; IIS control register    DCD 0x91600000, 0x56000000,  1  ; I/O Port register    DCD 0x91700000, 0x57000000,  1  ; RTC control register    DCD 0x91800000, 0x58000000,  1  ; A/D convert register    DCD 0x91900000, 0x59000000,  1  ; SPI register    DCD 0x91A00000, 0x5A000000,  1  ; SD Interface register    DCD 0x92000000, 0x00000000,  2  ;  2 MB SROM(SRAM/ROM) BANK 0    DCD 0x00000000, 0x00000000,  0  ; End of Table (MB MUST BE ZERO!)

This is modified according to the value of oemaddresstable in the original 5.0 BSP.

Then replace config. Big in BSP 5.0 with config. bib (my2410/Files) in BSP 6.0)

 

Go to the image_cfg.h file (my2410/src/INC) and change the following macro definitions to the following values:

#define IMAGE_SHARE_ARGS_UA_START       0xAC020000#define IMAGE_SHARE_ARGS_CA_START       0x8c020800#define IMAGE_SHARE_ARGS_SIZE           0x00000800 //------------------------------------------------------------------------------#define IMAGE_FRAMEBUFFER_UA_BASE       0xAC100000#define IMAGE_FRAMEBUFFER_DMA_BASE      0x30100000

 

Find the following four rows:

#define EBOOT_CONFIG_OFFSET         0x000F0000                                      #define EBOOT_CONFIG_SIZE           0x00010000#define EXTENDED_RAM_BASE     0x94000000 // This must match the "Extended RAM" #define EXTENDED_RAM_MEGS     192        // 192 Megs

 

These four lines are directly commented out. The first two lines are related to eboot configurations, which will be used in files under my2410/src/bootloader/eboot. as mentioned above, I didn't use the eboot of wince, so do not. the last two rows are used to expand the memory. these two macros are used in the oemgetextensiondram function (my2410/src/oal/oallib/init. c) Yes, because the memory is not extended according to the oemaddresstabel configuration, so this can be avoided, and then the implementation of oemgetextensiondram is cleared, leaving only one row: Return
False. This function will be called in the kernel's kernelfindmemory to set the extended memory.

 

7. Power Management

Go to the power. c file (src/oal/power), find the cpuclearcs8900 (void) function, and change its implementation to the following:

 

PRIVATE voidCPUClearCS8900(void){    USHORT temp;     do    {        temp = *((volatile USHORT *)(BSP_BASE_REG_PA_CS8900A_IOBASE + 8));    } while (temp != 0); }

In power. add void configmiscreg and configstopgpio functions in C. these two functions are called by the oempoweroff function, which is used to disable some IO resources when the system is shut down. for their implementation, see the power under the original 5.0 BSP. c file, but note that it can be used without directly copying it, because the methods for obtaining the addresses are different. For example, the original BSP obtains the preferred IP address for the IO port:

Volatile iopreg * s2410iop = (iopreg *) iop_base;

After porting to 6.0, it should be changed to the following form:

Static volatile s3c2410x_ioport_reg * s2410iop = (s3c2410x_ioport_reg *) oalpatova (s3c2410x_base_reg_pa_ioport, false );

 

All functions in powerstub. C (src/oal/power) have only one implementation, return True, for example:

BOOL OALIoCtlHalPresuspend(    UINT32 code, VOID* pInpBuffer, UINT32 inpSize, VOID* pOutBuffer,    UINT32 outSize, UINT32 *pOutSize) {    return TRUE;}

 

8. interrupt handling

Find the bspintrinit function (src/oal/oallib/Intr. c). According to the implementation of the oeminitinterrupts function in the original BSP, modify bspintrinit as follows:

BOOL BSPIntrInit(){    S3C2410X_IOPORT_REG *pOalPortRegs;    ULONG value;     OALMSG(OAL_INTR&&OAL_FUNC, (L"+BSPIntrInit/r/n"));     // Then get virtual address for IO port    pOalPortRegs = OALPAtoVA(S3C2410X_BASE_REG_PA_IOPORT, FALSE); /***************************************************************************/value = INREG32(&pOalPortRegs->GPGCON);OUTREG32(&pOalPortRegs->GPGCON, (value & ~(3 << 10))|(2 << 10)); //GPG5 == EINT13. value = INREG32(&pOalPortRegs->GPGUP);// Disable pullupOUTREG32(&pOalPortRegs->GPGUP, value | (1 << 5)); value = INREG32(&pOalPortRegs->EXTINT1);// High level interruptOUTREG32(&pOalPortRegs->EXTINT1, (value & ~(0xf << 20))|(0x4 << 20));     /***************************************************************************/    value = INREG32(&pOalPortRegs->GPGCON);// Set GPG1 as EINT9 for CS8900A    OUTREG32(&pOalPortRegs->GPGCON, (value & ~(3 << 2))|(2 << 2));     value = INREG32(&pOalPortRegs->GPGUP);// Disable pullup    OUTREG32(&pOalPortRegs->GPGUP, value | (1 << 1));     value = INREG32(&pOalPortRegs->EXTINT1);// High level interrupt    OUTREG32(&pOalPortRegs->EXTINT1, (value & ~(0xf << 4))|(0x1 << 4)); /***************************************************************************/ value = INREG32(&pOalPortRegs->GPGCON);// Configure EINT14 for dm9000 interrupt.OUTREG32(&pOalPortRegs->GPGCON, (value & ~(3 << 12))|(2 << 12)); value = INREG32(&pOalPortRegs->GPGUP);// Disable pullupOUTREG32(&pOalPortRegs->GPGUP, value | (1 << 6)); value = INREG32(&pOalPortRegs->EXTINT1);// High level interruptOUTREG32(&pOalPortRegs->EXTINT1, (value & ~(0xf << 24))|(0x1 << 24)); /***************************************************************************/    // Configure EINT8 for PD6710 interrupt    value = INREG32(&pOalPortRegs->GPGCON);    OUTREG32(&pOalPortRegs->GPGCON, (value & ~(3 << 0))|(2 << 0));    // Disable pullup    value = INREG32(&pOalPortRegs->GPGUP);    OUTREG32(&pOalPortRegs->GPGUP, value | (1 << 0));    // Low level interrupt    value = INREG32(&pOalPortRegs->EXTINT1);    OUTREG32(&pOalPortRegs->EXTINT1, (value & ~(0xf << 0))|(0x1 << 0)); /***************************************************************************/s    // Add static mapping for Built-In OHCI     OALIntrStaticTranslate(SYSINTR_OHCI, IRQ_USBH );     OALMSG(OAL_INTR&&OAL_FUNC, (L"-BSPIntrInit(rc = 1)/r/n"));    return TRUE;}

 

9 others

Find the init. C (src/oal/oallib/init. c) function and add two functions. These two functions are called

The implementation of initsdmmc and hzhinitpio functions can be directly copied from the original BSP (in the CFW. c file.

Then, the oeminit function calls these two functions.

 

The oal part should have some other things to be transplanted, but so far, the system can be started, and the peripheral driver is transplanted below

If you have any problems, go back and modify them.

 

Now the system can be started. The current startup information is as follows:
