[En-Nut-Discussion] Firmware >256K flash issue

[Mathieu SOULARD]

Hi all,

The binary file of my application has reached 256Ko today, and since I'm no
more able to get my board working. It seems I get an exception at boot time.

I'm using an EIR board, based on AT91SAM7SE512 including 512K of flash. I
was suspecting a bank issue, but openocd tells that there is only one bank.

I tried to flash using samba, the flash operation works like with openocd,
but my application does not boot also...

Does someone knows how to flash a firmware >256K with openocd?

Thanks
Regards

Mathieu


For information, here is my openocd log:
