TX2 NX RS232 Communication Problem

Hi JerryChang,

I followed your instruction but nothing output from THS2.

  1. It seems like THS2 is enabled.
p@p-desktop:~$ dmesg | grep THS
[    0.940063] 3110000.serial: ttyTHS1 at MMIO 0x3110000 (irq = 33, base_baud = 0) is a TEGRA_UART
[    0.941255] c280000.serial: ttyTHS2 at MMIO 0xc280000 (irq = 34, base_baud = 0) is a TEGRA_UART
[    0.942203] 3130000.serial: ttyTHS3 at MMIO 0x3130000 (irq = 35, base_baud = 0) is a TEGRA_UART

  1. After I removed “serial” part from Linux_for_Tegra/bootloader/t186ref/tegra186-bpmp-p3636-0001-a00-00.dtb.
    BPMP logs are not output now.

Is there anything I can check?

(I’m using TX2 NX with R32.5.1)

Thx
