Dear Support Team,

in the articel Configure Serial Port Debug Console is discripted how to disable the Console on the Serial Port. Is it possible to enable/disable the “Debug” Console only at runtime?
If yes, how can I do it?

hi Andre

Which carrier board are you using?

Could you provide some Information for your use case:

  • Why do you want to enable/disable the console at runtime?
  • How do you think to connect to the module, if the console is disabled?

Hi jaski,

I have an application that need the serial Interface for an serial bus protocol on UART_A. If the application is not started then the console are enabled else the application can use the UART_A.

I can’t use an other UART because my carrier board have no other connected UART.

Hi Andre

I could not find anything to switch the console at runtime, but if you use the UART_A for some different communication, maybe you can redirect the log messages to a different channel or reduce the console log level not disturb your serial communication. Check this post, please?

Hi jaski,

okay if I can’t switch off the console at runtime I will check if to reduce the console log level is engoth. Does the SSH connection works, if I disabled the console with ‘#fw_setenv console null’ - Can I enabled the console via SSH?

Yeah, you can connect using SSH to the module even if the console is disabled.

Additionally you can disable/enable the console through ssh, however you have to restart the module to take changes in account.
