BeagleBone Black UARTs

Postby dk23 » Sat Dec 12, 2020 6:22 pm

I need to turn on a UART for setting up NTPSEC. The last time it used cardmgr, that is no longer used. I'm assuming device tree are used with the newer kernels. In /dev the are ttyS? but nothing in /proc/device-tree to support the uarts. google seems to return cardmgr examples. Any pointers would be helpful.

Thanks

Find the right overlay and apply it in uboot is the new method: https://archlinuxarm.org/forum/viewtopic.php?f=23&t=12635
