Hi, everyone, my board is something similar to the public board
AT91SAM7X256. When I joined the packages "FLASH memory support for Atmel
AT91 EFC." and "Generic FLASH memory support." the redboot get hints like
that:
+Sorry, FLASH config exceeds available space in FIS directory
AT91_ETH: Initialising @ fffdc000
AT91_ETH - Warning! ESA unknown
AT91_ETH: 12:34:56:78:9a:bc
AT91_ETH: 10Mbyte/s Half Duplex
Ethernet eth0: MAC address 12:34:56:78:9a:bc
IP: 192.168.0.230/255.255.255.0, Gateway: 192.168.0.1
Default server: 0.0.0.0
.........................
RedBoot> fis list
Name FLASH addr Mem addr Length Entry point
RedBoot>
But actually the redboot can write the flash well(I have experimented) but I
can not use fis init to finish the initialization, neither can I do the
"fc -i" .
So, is there something wrong in the configuration? I have tried many ways
but I cannot solve this problem!
BTW:
The at91sam7x256 has only 64k ram, but my applications are too big to
download to the ram and I cannot debug them, so any good idea to fix that?
Thanks for your help!
