Flashing LPC2148 with OpenOCD r1888

Development Boards MicroMod

Hello.

I tried to flash LPC2148 using command:

“C:\Program Files\openocd-r1888\bin\openocd-ftd2xx.exe” -f jtagkey.cfg -c “flash write_image test.hex 0 ihex”

jtagkey.cfg is that one provided by Michael Fischer in mailing “Correct script to flash the lpc-2148” (http://lists.berlios.de/pipermail/openo … 07170.html) I just changed interface to Olimex and crystal to 12000

It ends up with such a problem:

30 kHz

Error: error writing to flash at address 0x00000000 at offset 0x00000000 (-902)

Please, can anybody suggest a solution?

Thank you

Hello Dmitry,

Try starting openocd in interactive mode (without the command). Then open a second “dos prompt” and telnet to openocd (telnet localhost 4444).

First issue the halt command, then enter your flash command. If that still fails, the output from that situation should give the experts here (not me!) something to sink their teeth into.

(If you get a timeout error waiting for the target to halt, you might try reducing the jtag speed in your .cfg file.)

Thank you, Hugh!

Things, you suggested gave the same negative result.

But I noticed, that programming works when I remove soft_reset_halt from “$_TARGETNAME configure -event reset-init” procedure!

But it reports errors in the beginning:

30 kHz

Error: JTAG communication failure, check connection, JTAG interface, target power etc.
