Problem #1 (hopefully, "of 1"!)
Just completed JA board and moving on to testing. On boot/reboot, I'm getting buttons 1, 2, 3 and 5 of the lower row lit on JA, and green light on SD board and red power on Wavemaker (see pic).
If I insert the SD card (FAT32 formatted with ther seq_l file in root only), I get solid amber light and flashing blue on SD board and all lights go out on JA board. This sometimes happens afer reboot without inserting SD card, but always if I do.
Logging from MIOS Studio looks like:
[blue block was reboot with card inserted, block above was without card inserted]
Feels like card *and* button (short?) issues? I can't find the button mapping refs through search...
I've reflowed the SD card connection - the last two are very tight but I don't see a short. Can't see a short on JA board either, but I'm squinting a bit after a day soldering :)
