... noticed this in dmesg: [ 4.003745] udevd[263]: starting eudev-3.2.9 [ 4.086853] imx-sdma 302b0000.dma-controller: loaded firmware 4.5 [ 4.354370] qca9377: loading out-of-tree module taints kernel.

So just finished the above cycle and flashed sdcard. Think we got somewhere this time! I get only one instance of sdma error: [ 0.117495] EINJ: ACPI disabled. [ 0.126332] imx-sdma 302c0000.dma-control

When I did NXP released builds I would use fsl-wayland distro but if memory serves me right a core-image-minimal would not boot. Only core-image-base images did and they were quite large. I do need to

I did a repo sync before building. Did I need to do something else? Regards, Brian

... what "distro" 'should' I be using since I have a custom board that's based on imx8mm evk but I don't necessarily want/need wifi, bluetooth, video, touchscreen etc.??? Is poky what's causing my pai

More background information in case it matters. I did my original setup with: EULA=1 MACHINE=imx8mmevk DISTRO=poky source setup-environment build ... because I don't want/need graphics etc. After Otav

So I did build of core-image-minimal with local.conf containing MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d' and still got the sdma errors. No firmware-imx packages were installed and no /lib/fir

Excellent! Thank you! I got to poking around in one of the include files and looks like I should have done: MACHINE_FIRMWARE = 'MACHINE_FIRMWARE_append_mx7d' ... instead of: IMAGE_INSTALL_append = " f

Hi Otavio, That's great! Just curious when was this done as I did a fresh repo init/sync of dunfell yesterday afternoon. repo init -u https://github.com/Freescale/fsl-community-bsp-platform -b dunfell

Another update ... decided to build core-image-base just in case it was related to core-image-minimal missing something ... I get the same sdma errors. So I add IMAGE_INSTALL_append = " firmware-imx-s

I'm using core-image-minimal because I have a custom board based off of imx8mm evk but don't use wifi, bluetooth, video, touch pad etc. so I don't want all the "stuff" that comes in core-image-base. J

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 lik

Ha, ha, I figured there was already some way to do it and I just overlooked it or wasn't smart enough to figure it out. Yeah, you can do anything with good ole sed. I plan to switch back to using the

When the sdcard is created, the u-boot environment has fdt_file defaulted to imx8mm-evk.dtb. I've not yet figured out how to override the recipe to specify which .dtb file should be used. For sdcard b

I'll answer my own question ... I applied the 5.4.54 rt patch and it worked. Built rt-tests and ran cyclictest and pi_stress so I'm happy. At this point looks like things are working as far as I can t

Hi, I'm looking into doing the rt patch against linux-fslc-imx 5.4.51. Doesn't look like anyone has done this for the imx8mm. I see a recipe for linux-fslc-imx-rt 4.1.-1.0.x but looks like it's for th

Which imx6 board are you using specifically? Regards, Brian

#define #yocto #compilation #meta-freescale

Andrey, I changed my local.conf and doing another buid to test with. I added the first two lines, the rest is stock the way it was created: PREFERRED_PROVIDER_virtual/kernel = "linux-fslc-imx" PREFERR

I don't think so. The core-image-minimal image I built with poky as distro boots clean when I replace the kernel with the one where I went into make menuconfig and turned off PCI and some other things

Update. I went into kernel config and gutted a bunch of setting for things I don't care about (wow ... 5.4 sure has a bunch of new stuff). I turned off PCI, bluetooth, wifi etc. I really think turning
