Hi All,
Hopefully I'm on the right list :)
Using a Gateworks Ventana board, powered by an i.MX6 soc, [1]
following errors were notice upon boot:
[ 22.617622] imx-uart 2020000.serial: DMA transaction error.
[ 22.623228] imx-uart 2020000.serial: DMA transaction error.
[ 22.628826] imx-uart 2020000.serial: DMA transaction error.
[ 22.648951] imx-uart 2020000.serial: DMA transaction error.
[ 22.654558] imx-uart 2020000.serial: DMA transaction error.
[ 22.660156] imx-uart 2020000.serial: DMA transaction error.
Kernel: 4.14.20
Within OpenWrt, we are circumventing the errors currently by disabling
DMA on UART using the patch from Tim [2]
Full bootlog attached.
This issue has been present since at least kernel 4.9
It's not critical as uart has been working perfectly fine without DMA,
and performance impact was negligible,
but it would still be better to get this fixed :)
Does anyone have any clue what could be causing this?
Highly appreciated,
Koen
