I have the same problem. If I link my program to the SRAM, it doesn't boot, but if I link to the Onchip_memory, without change any other parameter or the script, it boots!

I've checked what is written in the SRAM after boot, and it's not the right code, I don't no why! At the first direcction of the SRAm it should be:

14008200 33000010 04F8BF10 16FDBF00

However it's:

140020A8 33002872 04F89739 16FD581E

It's like it only writes the 16 first bits of every 32bits. Connections are right, because if I run it with Eclipse, it runs correctly! What's happening??
