I use 40 developing board. Firstly I can download my code into SDRAM using trace32 and everything is ok. But after I erase the flash, I cannot debug my code out of ram. Can everyone help me? Urgent!!!

Urgent!!! When the CPU comes out of reset it starts reading 0xFFFFFFFF from the Flash. That is an illegal opcode (condition = excute never) and the core crashes. JTAG then fails. The workaround is disabling the flash (jumper with pull-up in the CS line) and a pulldown on D28.
