hello shaorui,

you should also have modification to configure debug port from UART0 to UART1
for example,

  1. BCT changes, file name: tegra186-mb1-bct-misc-si-l4t.cfg
****************************
cpu.nafll_b_cluster_data = 0x11F04461;
##### debug variables #####
debug.enable_log = 1;
-debug.uart_instance = 0;
+debug.uart_instance = 2;
##### sw_carveout variables #####
****************************
  1. device tree changes to get kernel logs,
serial@3100000 {
- compatible = "nvidia,tegra20-uart", "nvidia,tegra186-hsuart";
+ compatible = "nvidia,tegra186-hsuart";
console-port;
sqa-automation-port;
status = "okay";

serial@c280000 {
- compatible = "nvidia,tegra186-hsuart";
+ compatible = "nvidia,tegra20-uart", "nvidia,tegra186-hsuart";
status = "okay";
};
  1. please add ttyS2 into kernel-command line,
-CMDLINE_ADD="console=ttyS0,115200n8 console=tty1 OS=l4t fbcon=map:0 net.ifnames=0";
