How to see syslog information instead of UART

My customer try to add their application to FX30 LTE-M model. To confirm their application, customer would like to see system log.
I know that it is better to check UART port for WP77xx/WP76xx module. But FX30 do not have UART port.
Please advise how to get system log on FX30 system.

You can then use dmesg and logread

Can customer switch UART syslog function to USB interface or SSH or Ether interface?

No, i don’t think so

Btw, you can try iot card with uart interface for debug purpose
