EWARM 5.40 on Atmel AT91SAM9263-EK

Wed Aug 05, 2009 12:33 am

I have been evaluating both IAR EWARM 5.40 and the AT91SAM9263 and have run into some interesting issues with the included example projects. In particular, the "getting started" project behaves differently in sdram and sram configurations. When building the sram configuration and using SAM-BA 2.9 to load and execute at 0x300000, everything works as expected. However, loading and executing the sdram configuration at 0x20000000 runs but hangs somewhere through the hardware configuration routines (it appears that it is barfing after the PIT interrupt fires once and jumps to some unknown location). Even more curious, if I build on EWARM 5.20, the sdram configuration works just fine.

Does anyone have any clues to this mystery?
