      I have an ARM9DIMM kit and need to debug and flash a new code.
      First I tried Keil ULINK2 jtag.ULINK2 detects the microcontroller but the NAND flash is not supported by Keil.
      Second I tried openocd and openjtag.The openjtag also detects the lpc3250 but I can´t debug due
      wrong configuration of openocd.I don´t know how to configure openocd for NXP LPC3250.
      Do you have the openocd configuration file for LPC3250 ?
      Is there any other jtag model that can be used to debug and flash ARM9DIMM ?

      Answered:

      We use Segger’s J-Link when doing JTAG transactions with their J-Link Commander, but it does not write to NAND directly.

      Instead, when writing to flash, we use u-boot. It’s ‘nand’ commands write to flash without issue. The Linux distribution we include with our SOMDIMM-LPC3250 module has that already pre loaded and if you need it, the binaries is also on our web page at (File Archived, Contact us through https://www.teamfdi.com/contact/ for the archived file)
