IM.X35 no serial(console) input (3.11.1)

[maxvankessel]

I'm using an I.MX35 SOC with the freescale linux mainline  (3.11.1).

I'm unable to receive any bytes from the serial input, the serial input/output (UART3) is connected to the console.

Someone an idea what is wrong?

Thanks,

Both Tx and Rx were configured for different pins.

Transmit was working (not configured), but receiver wasn't doing a thing.

Fixed the problem by changing the pins to the correct RS232 pins.

Does U-boot work? It would help if you could post your board file, boot logs, etc.

Hi Max,

I recommend you first to check the serial configurations, the speed is 115200 for example. And make sure if your board is working.

Best Regards
