Serial output is garbled [i.MX28EVA)

Discussion created by uuffmm uuffmm on Aug 8, 2012

I am trying the i.MX287 evaluation board as per reference manual. It is quite smooth. But I came across the following problem:   the Com1 output becomes garbled after decompressing the Linux kernel.

 

Please see my screen capture: The following is the printout of environment variables:
