Hello All,
I am working on a PPC405EP based target and hist upon this issue w.r.t the "struct flash_info_t flash_info[]" variable declared globally in the board/flash.c directory. My target has 128Mbyte SDRAM i.e. 0x08000000.
In the function "flash_init", for( i = 0; i < CFG_MAX_FLASH_BANKS; ++i ) { flash_info[i].flash_id = FLASH_UNKNOWN; }
I get a Bus Fault exception. My map file shows the following ... **************************************************** COMMON 0xffff8bb0 0x50c board/nms/CG6060/libCG6060.a(flash.o) 0x0 (size before relaxing) 0xffff8bb0 flash_info 0xffff8000 . = 0xffff8000
**************************************************** And after relocation to RAM the address shown is
I2C: Enabled DRAM: 128 MB Top of RAM usable for U-Boot at: 08000000 New Stack Pointer is: 07f87f38 Now running in RAM - U-Boot at: 07fc8000 FLASH: [flash_init, 56] Entering ... [flash_init, 57] flash_info = 0x08000BB0 ... Bus Fault @ 0x07fe5f0c, fixup 0x00000000 Machine check in kernel mode. **************************************************
The flash_info is @ 0x08000BB0, which seeme out of SRAM limit.
Have I messed up somewhere, or any clues where to look for the linker script information please ??
Warm Regards, Raghu.
