Im using the abive kit. OCD version is 2007-09-05

When I run OCD I get this ( via eclipse console)

Info: openocd.c:93 main(): Open On-Chip Debugger (2007-09-05 09:00 CEST)

Error: jtag.c:1253 jtag_examine_chain(): JTAG communication failure, check connection, JTAG interface, target power etc.

Error: jtag.c:1440 jtag_init(): trying to validate configured JTAG chain anyway…

Error: embeddedice.c:181 embeddedice_build_reg_cache(): unknown EmbeddedICE version (comms ctrl: 0x00000000)

Error: target_request.c:127 target_request(): unknown target request: a0

what does it mean?

I can read/write registers reset/halt target

I can’t read/write memory - always returns 0xFFFFF - jtag_speed?

Help!

Here is the OCD config

Hello… I have the same problem. I use ARM-USB-OCD with LPC2378Board from Olimex. But it is very weird, because in the beginning i can really debug my program into the target. But two days ago i after i made the debugging of the programm i write i coudln’t make the connection anymore. is it possible that the problem the programm i have debugged?

I got this error message:

I tried evetrything:I changed FPC Cable. I checked the voltage source ( I use 9 V external voltage source) But i just can find the solution…Please someone help me… Thank youuu :slight_smile:

Heloo,

Please help, can not I run programming via JTAG programmer OLIMEX for LPC1788 processor.

For LPC2478 and running of my work, now I want to convert FW for LPC1788, and I can not connect via JTAG with LPC1788 processor.

For LPC2478 i use this setting.
