Hi, I tried to copy all the memory from the FLASh to the RAM. When I try it with small code I succeed but when the code go larger (around 94Kbyts) I failed.
I work with at91sam7x512.
I do:
memcpy(mem_get_start_ram(), // dest mem_get_start_rom(), // source mem_get_size_rom()); // size
The start_ram - 0x00200000 The start_rom - 0x00000000 The size_rom - 0x00016FE0
after the memcpy it's go to prefetch abort, what did wrong?
thanks all, chiko
How can I know if so? where the stack locatd in the RAM?
From what I undersand the stack and the heap located in the end of the RAM. am I wrong?
In the Cstartup I do write this:
BSS_Start_Ptr Import |Image$$ZI$$Base| DCD |Image$$ZI$$Base| BSS_End_Ptr Import |Image$$ZI$$Limit| DCD |Image$$ZI$$Limit| ROM_Start Import |Image$$RO$$Base| DCD |Image$$RO$$Base| RW_Start Import |Image$$RW$$Base| DCD |Image$$RO$$Limit| + 0x200000 In the origin it was DCD |Image$$RW$$Base| ROM_Size Import |Image$$RO$$Limit| DCD |Image$$RO$$Limit| RAM_Start_Ptr DCD 0x200000
