imx6 sololite UART tx line activity while just receiving data

[jagsgediya]

Hi All,

We have a custom board based on the imx6 sololite.

We are facing the problem with the uart. We are just trying to receive the data through uart but when we are probing the Tx line, we are getting some garbage on it.

suppose I will do ,

cat /dev/ttymxc3

At this time also, I am getting some garbage on Tx line. Please help. What can be the reason?

Thanks,

Jags

Hi jags

reason may be short circuit with another signals,

recommended to test hardware UART lines

with i.MX 6Series Platform SDK

Best regards
