reading FLASH ROM contents on EBSA-285

[Paul Robertson]

I have just got a linux kernel running on EBSA285 I wrote a small hexdump program to dump the contents of FLASH I think that the FLASH on this board is at physical address 0x41000000 which maps to virtual address 0xd8000000. My program causes a segmentation fault like this...   bash-2.01# flashdump 0x100000 0x100100   flashdump: permission fault on section, address=0xd8100000, code 3 flashdump: permission fault on section, address=0xd8100000, code 3 Segmentation fault bash-2.01#   I thought that as root I would have access to system space. What is the easiest way around the problem?   Thanks for your continued support,   Paul Robertson LocSoft Limited "The key to your embedded solutions" www.locsoft.com Phone +44 (0) 1793 432557 Fax     +44 (0) 1793 432727
