Linux under USB burn write Uimage kernel

Linux under USB burn write Uimage kernel 1. Start the Development Board and enter the U-boot: (if there is no system in the board, you can start the board by using SD card)  u-boot 2011.06 (Mar 19 2012- 08:45:34) for mini6410 cpu: [EMAIL&NBSP;PROTECTED]FCLK = 667MHz, hclk = 133MHz, Pclk = 66MHz (ASYNC Mode) board:mini6 410dram:256 mibnand:512 Mibmmc:samsung sd/mmc:host controler ch0sd Card is SD_VERSION_2SD/MMC size:3911680 block * 5 12B = 1910mbvideo:no Video params found, try bootargs~~ 640x480x24 31kHz 59hz[petworm] Video_hw_init: <640, 480, 640, 480>error:bad gzipped dataerror:no Valid BMP or bmp.gz image at 57500000in:serialout:serialerr:serialnet:dm9000hi T any key to stop autoboot:3 2. After pressing any key into the command line state, run the DNW command, and the file storage address is passed in as a parameter (hex):  mini6410 # DNW 50008000Insert a OTG cab Le into the connector! 3. Plug in the USB cable, connect the host and the Development Board, Minicom will appear the following prompt:  usb Cable is Connectednow, waiting for DNW to Transmi T data 4. Another terminal, load Secbulk driver:  sudo insmod secbulk 5. Establish Secbulk Drive Device node (you can skip this step by experimenting):  sudo Mknod/dev /secbulk0 C 102 0 6. Run the DNW program to send the UIMThe file name of age with a path is passed in as a parameter:  sudo./DNW uimage_a70 # (We select the Uimage_a70 file in the current directory)   transfer starts after carriage, until the transfer is complete. The minicom tip is as follows:  now, waiting for DNW to transmit Datadownload done!! Download address:0x50008000, Download filesize:0x40de8checksum is being calculated.

At this point we can use the U-boot command to write the file to the corresponding Nandflash address:  mini6410 # NAND erase 80000 400000NAND erase:device 0 offset 0x80000, size 0x 400000Erasing at 0x460000 – 100% complete.

Adjust the S2 to the NAND boot position, restart the board and read the kernel to memory from the Nandflash, and run the following results:  u-boot 2011.06 (Mar 2012-13:58:27) for mini6410  CPU: [EMAIL&NBSP;PROTECTED]FCLK = 667MHz, hclk = 133MHz, Pclk = 66MHz (ASYNC Mode) board:mini6410dram:256 mibnand:512 Mi Bmmc:samsung SD/MMC: Host controler ch0no SD/MMC card detected!
