We use AT91EB40 but use another flash to replace the original flash.

We use arm-elf-gcc to build the bin file.

I selected the redboot template;
added generic flash memory support, support for atmel AT29xxxx flash memory, support for flash memory on ARM/AT91EB40 board, ARM AT91EB40 serial device drivers;
set startup type to ROM, debug and diag. serial port set to 0, disable thumb instruction set, interworking compiler option, without include GDB multi-threading debug support;
keep other things unchange like Redboot, Flash device drivers....
The selected flash AT29xxxx is not the same as our new flash but I still add it because without it the built process can't finish. [I haven't implement the flash program yet]

You mean there may be something wrong in hal_diag.c?
