General UART on Jetson TX2-NX (pin #203 - TxD and pin #205 - RxD)

Hi @JerryChang ,
I also have another question :

Also from TX2 NX RS232 Communication Problem - #14 by JerryChang, you said :

Enable THS2 with /Linux_for_Tegra/bootloader/tegra186-p3636-0001-p3509-0000-a01.dtb

However I can only find /Linux_for_Tegra/kernel/dtb/tegra186-p3636-0001-p3509-0000-a01.dtb

Is mine correct or the required file is missing?

Best regards,
K.
