Hi everyone,

I am working with the same processor I have the same problem. I try to booting from the internal flash but without success. I dont know why I can generate a checksum for bank B.
Below I show the address of images in the Internal Memory Flash:

Bank A-> 0x1A000000 (u-boot image)
Bank B-> 0x1B000000 (cheksum)

Currently I designed a kernel in uClinux for my hardware but I can't booting the embedded system, I test differents ways of booting without good results.

Sincerely

Cristóbal

Hi crchaves,
Did you also check status of port pin P2_7 during reset? This pin should be high during reset to boot from internal flash.

Hi mc,

Yes, I used a evalution board OEM with hardware accesible and in my case is the sw_6.

Hi crchaves,
Not sure what do you mean by

May be you need to post detail about project like How do you calculate signature of the boot image?
where is bootloder?
