Hi there,
I’m trying to integrate SWUpdate (by sbabic) inside my Yocto distro, using the NXP guides, which use the meta-swupdate-imx and swupdate-scripts repos as a reference.
I tried to make a port to Scarthgap (last branch for meta-swupdate-imx is Mickledore) and add config files for imx95 (last is imx93).
I should be at a good point of the integration, but I noticed that the tool fw_printenv can’t access U-Boot env variables. Log:
~# fw_printenv
Cannot read environment, using default
Cannot read default environment from file
At the moment, the file /etc/fw_env.config is:
/dev/mmcblk0 0x700000 0x4000
/dev/mmcblk0 0x704000 0x4000
That’s because in the uboot defconfig (in my case, I'm using iMX95 Verdin from Toradex, but the config is basically the same for imx95evk except for dtbs) configs/imx95_19x19_verdin_defconfig I have:
CONFIG_ENV_SIZE=0x4000
CONFIG_ENV_OFFSET=0x700000
and the NXP patches also include:
+CONFIG_SYS_REDUNDAND_ENVIRONMENT=y
+CONFIG_ENV_OFFSET_REDUND=0x704000
But it’s not working… Does someone know how to deal with it?
Thank you
