Hi all, I want to program *.or32 to flash rom with the flash programming device.When powerup or1k can read instruction from the flash rom. So I can't use the gdb and jtag program. Then I want to write a program to convert the *.or32 file to the file which my flash programming device support.Should I know any about the *.or32 format? Could someone give me some suggestion? Thanks and Regards -------------- next part -------------- An HTML attachment was scrubbed... URL: http://www.opencores.org/forums/openrisc/attachments/20041018/bc4508b2/attachment.htm

You want to use the 'objcopy' utility with the GNU tools. Assuming you want a binary file, you would do the following: or32--objcopy -S -O binary Where: is your toolchain target, e.g. elf, rtems. is the input or32 file is the output binary file For other formats, e.g. Intelhex, S-records, look at the manual for objcopy ('man objcopy' or 'info objcopy') Robert Cragie, Design Engineer _______________________________________________________________ Jennic Ltd, Furnival Street, Sheffield, S1 4QT, UK http://www.jennic.com Tel: +44 (0) 114 281 2655 _______________________________________________________________

You don't need to write a program - it is already there: or32-elf-objcopy (or or32-rtems-objcopy, or32-uclinux-objcopy depending on how you have built your tools). To convert or32 file to binary, do: or32-elf-objcopy -S -O binary yourfile.or32 yourfile.bin objcopy can also convert to S records, Intelhex, whatever your programmer needs - look at the manual pages for objcopy.
