Just built latest Freescale Community BSP core-image-minimal (kernel 5.4.67 was built) for imx8mm-evk and firmware-imx is not included in sdcard image ... which I think is why I'm getting messages like these:<br /><br /><span style="font-family: monospace;"><span style="color: #000000; background-color: #ffffff;">[ &nbsp;&nbsp;&nbsp;0.127623] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2 </span><br />[ &nbsp;&nbsp;&nbsp;0.127636] imx-sdma 302c0000.dma-controller: Falling back to sysfs fallback for: imx/sdma/sdma-imx7d.bin <br />[ &nbsp;&nbsp;&nbsp;0.135771] mxs-dma 33000000.dma-controller: initialized<br /><br /></span><br /><span style="font-family: monospace;"><span style="font-family: monospace;"><span style="color: #000000; background-color: #ffffff;">[ &nbsp;&nbsp;&nbsp;3.921734] cfg80211: failed to load regulatory.db &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</span><br />[ &nbsp;&nbsp;&nbsp;3.939089] imx-sdma 302b0000.dma-controller: external firmware not found, using ROM firmware &nbsp;&nbsp;&nbsp;<br />[ &nbsp;&nbsp;&nbsp;3.939090] imx-sdma 30bd0000.dma-controller: external firmware not found, using ROM firmware &nbsp;&nbsp;&nbsp;<br />[ &nbsp;&nbsp;&nbsp;3.939186] imx-sdma 302c0000.dma-controller: Direct firmware load for imx/sdma/sdma-imx7d.bin failed with error -2 <br />[ &nbsp;&nbsp;&nbsp;3.966989] imx-sdma 302c0000.dma-controller: Falling back to sysfs fallback for: imx/sdma/sdma-imx7d.bin &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<br />[ &nbsp;&nbsp;&nbsp;4.013621] imx-sdma 302c0000.dma-controller: external firmware not found, using ROM firmware<br /><br />I found the firmware files in:<br /></span></span><br /><span style="font-family: monospace;"><span style="font-family: monospace;"><span style="font-family: monospace;"><span style="font-weight: bold; color: #5454ff; background-color: #ffffff;">build/tmp/work/aarch64-mx8mm-poky-linux/firmware-imx-8m/8.8-r0/firmware-imx-8.8/fi</span>rmware<br /><br />... and copied them to the sdcard under /lib/firmware/imx directory but I still get the firmware errors.<br /><br />How "should" I be getting these firmware binaries into the core-image-minimal sdcard image to also get rid of the firmware loading errors?<br /><br />I'm using a rev B imx8mm-evk board and using the imx8mm-evk-revb.dtb.<br /><br />Regards,<br /><br />Brian<br /><br /></span></span></span>
