Hello, I do have a Problem booting my BeagleBone with a custom cape on. I already double checked my layout, i did not use any pins marked with mmc1 in the pintables of the system reference manual.
It will not boot if the cape is on. If I just plug in P9-Capeheader, it does boot. If I plug in the cape when the bone is up, it works. For my PinOut I used http://exploringbeaglebone.com/wp-content/uploads/resources/BBBP8Header.pdf from Derek Molloy and I didn't touch any of the marked pins but those "allocated for HDMI". I suppose the Problem might be there, though I disable the HDMI in the uEnv.txt. On P8 I use the following Pins: 11,14,15,16,17,19,31,32,33,34,35,37,38,45 Here's the dump of a Startup with the cape on: =~=~=~=~=~=~=~=~=~=~=~= PuTTY log 2016.05.27 14:28:54 > =~=~=~=~=~=~=~=~=~=~=~= > @uiP#!…W%ZDŒ XFPF©U > > > ü > > U-Boot 2015.01-00001-gb2412df (Jan 29 2015 - 15:01:06), Build: > jenkins-github_Bootloader-Builder-105 > > Watchdog enabled > I2C: ready > DRAM: 512 MiB > MMC: OMAP SD/MMC: 0, OMAP SD/MMC: 1 > Using default environment > > Net: <ethaddr> not set.
