Dragonboard 410c UART technical specs

Products Support DragonBoard410c

Hi,

Just bought the dragonboard 410c and want to install Xen on it, but it seems there is no compatible UART driver in Xen for this board.

I started porting Linux msm7x driver, but I am unsure about the initializing sequence.
If anyone has an idea where I can find the datasheet for the UART controller, I would be very grateful.

Thanks,

Doesn’t Xen need to run at EL2 on AArch64 machines? If so I’m afraid you cannot port it to DB410C… like most other Qualcomm consumer platforms EL2 is reserved by the firmware for system management.
