Yesterday I checked out Hardknott (creating layers manually
due to repo sync issues) and tried to build core-image-base
for my imx8mm-evk.
First I noticed that there wasn't a machine config for
imx8mmevk (as there was for Dunfell, Gatesgarth etc.), but
there was a config for imx8mm-ddr4-evk so I used that in my
There are two configs for imx8mm EVKs, one for ddr4 and one for
lpddr4. Check your board so you get the correct one. 8MMINILPD4 =
lpddr4 and 8MMINID4 = ddr4. I have a imx8mm_lpddr4_evk in my
project ad have been able to build hardknott without issues.
Yes, the LPDDR4 version has a NAND flash if memory serves me right. Mine is the older version (Rev B) DDR4 version with eMMC and NOR flash.
source setup-environment build
need the 5.10 kernel, but did not see the trick Andrey
showed me to change:
IMX_DEFAULT_BSP = "mainline"
... in machine .conf to
switch to linux-fslc, so I just put this in my
PREFERRED_VERSION_linux-fslc = "5.10%"
This is not needed in hardknott as imx8mm-*-evk machines are
using mainline and linux-fslc by default.
Any advice on what to do
or try next is greatly appreciated.
The error you see below is because the u-boot configuration
imx8mm_ddr4_evk is not present in u-boot-fslc. There is only
imx8mm_evk config that is intended for lpddr4 variant. This is an
error in the configuration in Yocto but I'm a bit unsure the way
One thing you can try is to use u-boot-imx instead by adding:
PREFERRED_PROVIDER_virtual/bootloader = "u-boot-imx"
I'll try that and see what happens!
