Hello Kevin, I am using openocd debugger with an lpc2468 in an olimex board to.
I am using the openocd release 0.1.0 now, but for some time i was using the trunk. I have some strange behaviors too. Some times after flashing a program I can not get more access over the jtag if I made a hardware reset or a "monitor reset" but until then works. After a reset or a "monitor reset" command I can not get more contact and I get the error: arn : Tap/Device does not have IDCODE Error: JTAG tap: lpc2468.cpu got: 0x00000000 (mfg: 0x000, part: 0x0000, ver: 0x0) Error: JTAG tap: lpc2468.cpu expected 1 of 1: 0x4f1f0f0f (mfg: 0x787, part: 0xf1f0, ver: 0x4) Error: trying to validate configured JTAG chain anyway... Error: unknown EmbeddedICE version (comms ctrl: 0x00000070) Warn : no telnet port specified, using default port 4444 Warn : no gdb port specified, using default port 3333 Warn : no tcl port specified, using default port 6666 Error: invalid mode value encountered Error: cpsr contains invalid mode value - communication failure Warn : DBGACK set while target was in unknown state. Reset or initialize target. Error: invalid mode value encountered Error: cpsr contains invalid mode value - communication failure Error: invalid mode value encountered Error: cpsr contains invalid mode value - communication failure Warn : DBGACK set while target was in unknown state. Reset or initialize target. Error: invalid mode value encountered Error: cpsr contains invalid mode value - communication failure and so one, the last 3 lines are repeted every x time again and again. Every time that I have this problem I flash back a start example using the serial interface and lpc21isp-1.64 software or flash manager from windows to load an other software and then i can use the debugger again. I have no idea where is the problem, but I am sure is not a problem regarding security flag of the lpc since the value on the position 0x1fc (i dont remember if this or which posistion) but is not protected. So is an other issue. I am using the cfg file attached to the mail.
