- Subject: [ECOS] Running Firmware from external SRAM on AT91SAM7SE512
Did anyone run its firmware from external SRAM (total 2MB address starts from
0x20000000)?
I am using the BDI2000 emulator to run the firmware.
I have moved my firmware from the flash memory to the external SRAM, and I
encountered a problem that I cannot resolve. The firmware hang on the
cyg_thread_delay() function. When stop the BDI2000, the external SRAM
become all 0xFF.
Did anyone has experience to resolve the issue?
