can metrowerks's codewarrior complile the u-boot? i want to port the u-boot to my arm lpc2210 in linux , but the board don't give the jtag driver that can write/read flash in linux ,so i want to complile the u-boot in codewarrior and write into flash by jtag in windows

a) The AXD Debugger is able to load the compiled u-boot loader even if it was not compiled with Metrowerks Codewarrior. Of course, you have to select to load *.* and not *.axf files. So there is no need to compile it under Metrowerks. b) I'm quite sure that gdb can communicate with your JTAG interface, if the AXD debugger can do so. The AXD Debugger uses the Arm/Angel protocol and the gdb can do so, too. If the gdb has ARM support compiled in, it automatically adds the necessary RDI entries for Arm/Angel support via ethernet and serial interface. Therefore you can load u-boot into memory via JTAG, execute it and use u-boot to write to flash.
