Subject: [ECOS] Running Firmware from external SRAM on AT91SAM7SE512
Date: Mon, 07 Dec 2009 08:37:00 -0000	[thread overview]
Message-ID: <26674151.post@talk.nabble.com> (raw)


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?
