Wondering how to change the mode of P1_28 to CAN0RX and P1_26 to CAN0TX as shown in the wiki:
https://github.com/beagleboard/pocketbeagle/wiki/Peripherals#can
It doesn't appear as though CAN is an option for those pins?
---
debian@beaglebone:/$ config-pin P1_28 can
Invalid mode: can
debian@beaglebone:/$ config-pin -l P1_28
default gpio gpio_pu gpio_pd spi i2c pru_uart
debian@beaglebone:/$ config-pin -l P1_26
default gpio gpio_pu gpio_pd spi i2c pru_uart
debian@beaglebone:/$

Apologies if this is covered somewhere, I am still getting up to speed on this cool little board. Thanks in advance!

you'll also need to update bb-cape-overlays package:
So just run:
sudo apt update ; sudo apt upgrade
sudo /opt/scripts/tools/update_kernel.sh
sudo reboot
