Issues with serial on iMX6

Question asked by bogdan anton on May 9, 2017

Hello we use iMX6DP4AVT1AA  devices in a hardware setup running on windows7 32bit and libusbx-1.0.15-win 

 

We face some problems on the serial hardware, where we have a FTDI232RL + 3.3V level translation  to comunicate with the iMX chip  .

 

Sometimes the test system fails when waiting  for  iMX boot console response. 

 

Is there any hardware alternative to ftdi232rl chip for comunication with imx?

 

We tryied a alternative using the native COM1  via a max232 + optical isolation and level translation, but the results where worst 

 

Any sugestions?

 

Thank you
