177Re: Use J-link to download gcc compiled code?
- Feb 18, 2008Swapping the ELF file might work for debugging (I haven't tried it
It looks like to actually program the flash you need IAR's debug
output file [ .dxx ] and IAR's simple binary format [ .sim ] which
allows you to use their flash loader to program the flash. The flash
loader is a RAM resident program that downloads the code but to use
IAR's I would need to convert the output from GCC to the two formats
used by IAR.
I haven't found any simple solutions yet. I think using the jlink-GDB
server to download
A flash loader to RAM would work but then I would either need to know
the USB/JLINK interface or have the flash loader download from the
UART. I haven't looked in to it yet but OpenOCD looks like it has
potential since there is supposed to be a patch so the JLINK works
