Unable to configure pins #76

Unable to configure pins

I am attempting to setup Beagle Bone Wireless using the new U-Boot Overlays. When I try to configure any of the pins I get the following errors:

GPIO: debian@beaglebone:/var/lib/cloud9$ config-pin P8.03 gpio
P8_03 pinmux file not found! Pin has no cape: P8_03

PWM: debian@beaglebone:/var/lib/cloud9$ config-pin P9.14 pwm P9_14 pinmux file not found! Pin has no cape: P9_14

Following recommendations found for related issues I have updated the kernal and the boot loader. I have tried configuring many other pins with the same result. Based on documentation here: https://github.com/cdsteinkuehler/beaglebone-universal-io all pins are enabled and in a default condition. It looks like Cape Universal is not loading.

What am I doing wrong?

Best regards,

Jack Walker

@jackw2050 

bootloader:[eMMC-(default)]:[/dev/mmcblk1]:[U-Boot 2016.11-rc3-00002-g73df7f]:[location: dd MBR]

Your old bootloader in the eMMC is block u-boot overlays, you can fix it via:

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

and since your running:

kernel:[4.14.29-ti-r40]
uboot_overlay_options:[uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-9-TI-00A0.dtbo]

Change in /boot/uEnv.txt, to get the correct pru overlay.

uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-9-TI-00A0.dtbo
to
uboot_overlay_pru=/lib/firmware/AM335X-PRU-RPROC-4-14-TI-00A0.dtbo

also make sure the bb-cape-overlays package is upto date..

sudo apt update
sudo apt install --only-upgrade bb-cape-overlays

It is working correctly now. Thank you for the help and quick response.

I am having a similar issue with the exception being that I have an NHD-7.0CTP-CAPE-N display attached. Without the display all works as it should. When the display is attached I have the above problem using to use GPIO pins and UART1, UART4, and SPI0. I believe I have done the updates listed above. Below is the listing from sudo /opt/scripts/tools/version.sh. Any help is appreciated.

OK - I found that by adding the following line to the uEnv.txt the config-pin function works but, the touch screen function does not?

Success. Thank you very much for your assistance and have a great day.

gemlrm commented 6 years ago

All seems good until you loose the SPI bus. Display and touch are working, but SPI is now gone. Config-pin is showing correct for uart and spi.

ls -al /dev/spidev* returns no such file or directory.

Any thoughts on this?

i have bought a COMMS cape for my BeagleBone Black wireless. i want to use it to get CAN message. But i have not fund the overlay for this cape. I want to know, do i need to manual configure Pin P9.24 and P9.26 to CAN.

@sychen917 , please don't directly spam everyone on a closed issue.

In /boot/uEnv.txt use:

uboot_overlay_addr4=/lib/firmware/BB-CAN1-00A0.dtbo

Should achieve what you want, but open a new issue, i'll be locking this "closed" issue.
