Hi, Has anyone else tried using the debug board? I tried for the first time last night and thought I'd share my experience.
First, I had a hard time getting it connected. I was not previously familiar with the connectors for the ribbon cable, and it wasn't clear how far the cable must be pushed into the connector. The pictures on http://wiki.openmoko.org/wiki/Connecting_Neo1973_with_Debug_Board_v2 were useful, but it still took me a while to get it connected. Second, while I did get openocd working with it, I was never able to get serial output through the debug board. /dev/ttyUSB0 appeared on my Linux laptop, but using minicom on it (115200 baud, no/hardware flow control, 8N1) didn't produce any output. I tried "setting the console to serial" through the bootloader, but no luck. I've taken the "console=ttySAC0,115200" out of my kernel boot command line by changing the u-boot environment variables, so I didn't expect kernel output. Neither the getty on ttySAC0 or 'echo "foo" > /dev/ttySAC0' produced any output in minicom. Third, I saw the debug board in the output of "lsusb" on my laptop, but not the Neo when it was plugged into the debug board. I was unable to use usbnet. Luckily, my laptop has three usb ports, so I just plugged the Neo directly into the laptop. Finally, the Neo didn't charge when connected to the Debug board. Is there more documentation available about the debug board? For example, what do the various LEDs mean? Are schematics available? On Harald's blog, I see that he mentioned a version 3 of the debug board. What changed? I thought that the intent was to make no major changes to the debug board. Will the one I have will work with the GTA02? Having fun, Greg
