Problem with capes

[marcozamb...@gmail.com]

HI all,
I have some problems enabling capes on my BBB. When I query config-pin -q "pin_name" I get:

"pin_name pinmux file not found!
Pin has no cape: "pin_name"

on every pin except the one not modifyable i.e.:
#config-pin -q p9.04
Pin is not modifyable: P9_04 3V3

There is the uncommented lines  in /boot/uEnv.txt:

uname_r=4.9.82-ti-r102
enable_uboot_overlays=1
enable_uboot_cape_universal=1
cmdline=coherent_pool=1M net.ifnames=0 quiet

There the result of /opt/scripts/tools/version.sh

Thanks

PS: My objective is to enable all UART, PWM, I2C and let every other pin as available GPIO. (Disabling eMMC,HDMI...)

Your u-boot installed to the eMMC is breaking things...

sudo dd if=/dev/zero of=/dev/mmcblk1 bs=1M count=10

Thanks very much,
erasing eMMC partition solved the problem
