Hi,

I have recently updated my distro version for being generated with Yocto Sumo instead of Yocto Rocko. After launching kernel  I begin receiving messages complaining about sdma in serial ports:

 

imx-sdma 20ec000.sdma: sdma firmware not ready!
imx-uart 21f0000.serial: Prepare for the RX slave dma failed!

Same image with kernel 4.9.88 has no problems with serial ports. Any idea?

 

Thanks
