I am having two TX1 board.
And both TX1 module is having R24.2.1.
During some development testing, One TX1 module freezes and supply LED CR1, CR2 suddenly off at the time of booting.
Below is the last valid logs

During the hardware check, I find vdd_1v8 found short with GND.
I tried to reset power and restart but there was no log on UART and no CR1, CR2 LEDs. But 5V & 3.3V supply seems ok.
I replaced U9. Now there is no shorting between 1.8v to GND. And now tried to start TX1. This time Both CR1, CR2 LEDs light up and 1.8V appears OK. But Same NO UART log and TX1 not booting UP.
But if I place the same module to another TX1 kit it powers up successfully.
So, I think there is something wrong with my first TX1 kit board.
I checked all the power section it seems OK to me.
Please guide me to make my faulty TX1 kit comes alive…!!!
