Hi Liao,

Are you loading them through MMC/UART/... etc.

which application?

It seems bootloader is working fine. but unable to load the file.

Is the application file name modified as expected in bootloader program.

I load it through NAND flash .
The application is to twinkle the led on my board , and it can boot from nandflash without ubl normally.

I found that the code sections are moved to memory as the map file correctly, but when it jumps to the entryPoint,the application can not run!

Is my DDR2 memory configuration wrong or some other reasons?

thanks!

Hi Liao,Are you writing the application at the proper address in NAND?.
If every thing is done proper, I think it will be better to debug using CCS!
Have you run any other applications on the same board? Regards,Murali Krishna

I think I have writen the application at the proper address in NAND,so that the rprc header can be analyzed by the ubl!!

How to use CCS to debug?

Best regards.
