I found this in the datasheet:

If the printed information [on UART0] exerts any influence on the functionality of your device [yes it disturbs my communication protocol], you’d better block the printing during the power-on period by changing (U0TXD,U0RXD) to (MTDO,MTCK).

But dont see how to do that.
Any hint is welcome.

Thanks

how to turn UART off

2015-12-27T17:47:47+08:00

Hello all,

during boot and wifi connetion UART0 outputs some messages I dont wanna see.
But I cannot find a way to turn it off.
Is there a UART enable bit? Or can I set UART_CLKDIV to zero?

thanks Carsten
