I have reverted this patch and the serial comm is working well.
I haven't been able to test with the SDMA firmware, yet.
Thank you for the bug report
Hi,
Okay, please inform about your results. I think I had that one and the

I believe it is this one [1], but I will be only able to test

Hi,
I believe I'm also affected by this BUG. I'm receiving lots of 0 and 1
(ASCII, as presented by cat /dev/ttymxcX) and RX buffer is
overflowing.

I believe I'm also affected by this BUG. I'm receiving lots of 0 and 1

overflowing.
the firmware only supports imx6 series, AFAIK,
