HI ,  
I have one board which fails in quick test and also gets very hot. Logs attached. Do anyone has idea what could possibly go wrong?

Looks like there may be damage to a Tx/LNA port.

@Zack, do you have anything to suggest?

Hi @rohit.soni,

Update the firmware to the latest and try LimeQuickTest again, please. If the same problem remains, then contact CrowdSupply for replacement.

Hi @Zack,  
Did update on the same board. The firmware still did not updated and the LimeUtil --update command says no need to update and stays on 22 version.
