dmatest getting failed in I.MX8QM board

[mallibeerala]

Hi,

I am using I.MX8QM Eval Board.

Here I am testing dmatest, but it is getting failed with reason "dstbuf[] not copied! Expected 0xdf, got 0x3f".

I am running following commands from userspace.

echo dma0chan0 > /sys/module/dmatest/parameters/channel
echo 2000 > /sys/module/dmatest/parameters/timeout
echo 1 > /sys/module/dmatest/parameters/iterations 
echo 1 > /sys/module/dmatest/parameters/run

Please help us to resolve this Issue.

Thanks & Regards,
Mallikarjuna

Hi Jimmychan,

I am asking about dmatest, but in below thread it is for sdma.

Thanks,
