Thanks, Kevin! Yes, I just pulled the pm branch and the Overo is booting again. A few quirks to note: 1) As I hadn't grabbed the fixes for the OMAP4 compilation problems, I had to uncheck OMAP4 in the System Types as before. 2) Since I was booting off an SD card, I had to go to Device Drivers-->MMC/SD/SDIO Card and have the following be built in (rather than be a module) - MMC block device driver - SDHC Interface support - TI OMAP High Speed Multimedia Card interface support 3) I have a few error messages with the framebuffer as the kernel is booting up. It does still work, however. See [1] below. 4) Suspend to memory (echo mem > /sys/power/state) works now, but when I wake up the board (via a keypress), I am no longer able to type anything at the prompt. Any clue about this one?
