i.mx6DL cant send data through UART2,3.

Hello,

Target environment is Android 4.4.2 .

I installed UART2,3 with tested i.mx6Q quad processor without problem.

device is /dev/ttymx1, /dev/ttymx2

But processor MCimx6U5DVM10AC board can not run UART 2, 3 .

So question is I.mx6DL processor UART port has difference with Quad processor?

Hi IS

DL has different than DQ registers addresses, also suggest to

look at attached Porting Guide Chapter 3 Registering a New UART Driver

Best regards

igor

thanks for your response.

it was corrected by port pin mapping change.
