Mini2440 use jlink to burn superboot to norflash, jlinksuperboot
Jlink version: J-flash ARM V4.12

J-Flash ARM configuration.


Generally, some configuration files *. jflash can be found in file --> open project and loaded. However, the configuration files suitable for S3C2440 are not found. Therefore, you have created a mini2440.jflash and configured it manually:


J-link settings
1. Open J-Flash ARM and choose Options> Project settings.
2. Set CPU options and Flash options.
CPU:
Core --> ARM9. Little endian


Use target RAM (faster) --> Addr: 40000000 4KB (not selected very slowly; the address and size of the internal Boot SRAM when the Nor flash is started, refer to the S3C2440A chip manual)


The initialization sequence (Init sequence) is simply commented out in the following field.

3. Flash


Cancel "Automatically detect flash memory" and then "Select Flash Device ".
The Flash model of mini2440 is AM29LV160DB or SST39VF1601. Do not rewrite any value after selection.


If there is no corresponding Flash model, select Automatically detect flash memory


Set.


4. Burn the. binfile. (if the extension of the binary file is not. bin, change it to xxx. bin)


1) Open the. binfile (bootloader): File-> Open data file


2) Target-> Connect


3) Target-> Erase chip

4) Target-> Program

When connecting the USB interface, you must unplug the Jlink line. Otherwise, minitools cannot connect to the Development Board.

Why did the display fail to display after using JLink to burn Nand and Nor Flash?

You have downloaded Uboot or supervivi, and then loaded the kernel and root files.
We recommend that you first use Jlink to write supervivi to NorFlash, then start the development board under NorFlash, input f to erase the NAND data in the Super Terminal, and then run v to write supervivi to NAND in sequence, k. Burn the kernel, select the kernel based on the W35 or X35 on the screen, input y to burn the root file of QT4, and use the DNW tool to burn the kernel, in this way, you can see the penguin at the start of NAND. Read the mini2440 manual in detail.
 
I wrote supervivi or u_boot to nor flash at mini2440. Why did I use it?

It is also an experiment. The mini2440 can be started in either Nor or Nand. No matter which method you want to start, you need BootLoader. the BootLoader mentioned here is Supervivi and Uboot. I will not repeat the importance of Bootloader because I have a lot of information on the Internet. PS: Supervivi is suitable for beginners, while Uboot is more flexible. It provides download methods such as TFTP, NFS, and serial port.
