I’ve been using WP76 Firmware R9 for a while.
It contains Linux version is 3.18.44 and the UARTs are coupled to ttyHS0 and ttyHSL1.
When I upgrade towards Firmware R12, I see that the Linux version is 3.18.122,
and the UARTs are coupled to ttyHS0 and ttyHS1.
I assume that this change is related to the changes in the Yocto sources:
What is the reason behind this change?
