After my test with privious settings for turn off logs
enable_combined_uart = 0;
spe_uart_instance = 0xff;
Verbosity = 0; # 0: Disabled: 1: Critical, 2: Error, 3: Warn, 4: Info, 5: Debug
System will stuck at bootloader if turn kernel log off
System will boot properly if turn off bootloader message and keep kernel log on.
In Xavier NX mb1 misc config, it does’t have those settings to be modified
debug.enable_log = 1;
-debug.uart_instance = 0;
+debug.uart_instance = 2;
Instead , it uses combine uart feature ,seems logs are come from ttyTCU0 along with ttyTHS0 port
enable_combined_uart = 1;
spe_uart_instance = 0x2;
Does it uses other way to change console log uart or close tegra-combine-uart feature ?
