Gunter (Sorry for the typo, not using good behaved keyboard), thanks for your reply! Since I am on 3.14, i have no capemgr to make sure it is really not loaded. I am not sure if I completely got your idead, but the framer being active or not should not pose an issue, the big problem is if its driver is sending data over GPIO2. Also, I don't know where the real uEnv.txt file is stored in my eMMC. Here is the output of lsblk:
mmcblk0boot0 179:8 0 2M 1 disk mmcblk0boot1 179:16 0 2M 1 disk mmcblk0 179:0 0 3.6G 0 disk ├─mmcblk0p1 179:1 0 96M 0 part └─mmcblk0p2 179:2 0 3.5G 0 part / mmcblk0p1 is a partition that gets mounted as storage when i plug the board over USB and I don't know if those mmcblk0boot* have a filesystem or not (raw data?), all I know is that I can't mount them with mount /mmcblk0boot0 /mnt/bp0. Any other thoughts on this? Thanks again! Paulo Sherring.
