Re: [psas-avionics] Programming LPC2148 with JTAG -- directions?
The openocd group has changed the commands for the configuration file many times. I have been keeping working examples for the lpc2148 by openocd version number. I think a link needs to be changed or made. I'll check it out. While working with Mike and Jeremy we found out that something is broken in the poke program. You will need to comment out Test2 to get it to run right. I thought I had pushed a new version but maybe not. Comment out: // Test 2; // serial i/o //puts(Type something to continue. LOCAL ECHO ON?\r); // echo_line(); This is a poke.c bug, so it sounds like you've got your tools working fine.

However, the board isn't echoing anything I type at it, so I'm concerned the board can't hear me. The screenshot shows a serial only connection, but I can't use a straight serial cable because my host PC doesn't have a serial port. Suggestions?

I couldn't remember if there needs to be an other USB cable from the LPC2148 to the host PC or not when I'm trying to program the board. 1. Make sure to set the Olimex JTAG programmer to 9V by jumpering on the right-most pins (the two farthest away from the JTAG cable). 2. Plug a USB cable from the JTAG programmer to your computer. 3. Power the LPC2148 dev board by plugging it into the JTAG programmer with the white cable. 4. Make sure the LPC2148 debug jumper is jumpered (the DBG_E pins are next to the JTAG port) 5. Set both dip-switches on the LPC2148 board to the 'off' position. Did I miss anything? I'm putting these directions into the documentation for the project, since they seem to be scattered between the Keil documentation, the Olimex schematic, and the PSAS wiki.
