I was looking at the u-boot source on the open2x cvs server and noticed that the version from MagicEyes includes support for UARTS (serial ports). We really need to get the version from GPH to figure out which UART the shipped UBoot version supports (if at all).
I was wondering if anybody has any close-up pictures of the GP2X's EXT port without the cover in place. I want to see the pin arrangement. I know that the wiki says that there are UARTs, JTAG, and DAC outputs in the 24 pin port. Has anybody figured out which pins are for what purposes?
If I can get a picture of the pin arrangement, I'll probably be able to track down a source for connectors so that I can build a serial "coder's cable". Using u-boot you can upload executables over the serial cable into RAM and execute them. This would be the way to get around the Linux kernel for development purposes, though I don't think you would be able to ship a game like that since the GP2X boots into Linux by default and not your game.
Anyway, anybody got any more info on the EXT port.
