Yocto meta-freescale layer is already using this firmware version for mx8m series [1], and it is operable. I believe it would be beneficial to recommend users to pull the latest version available. > +$ chmod +x firmware-imx-8.5.bin > +$ ./firmware-imx-8.5 > +$ cp firmware-imx-8.5/firmware/ddr/synopsys/lpddr4*.bin $(srctree) > + > +Build U-Boot > +============ > +$ make imx8mn_beacon_defconfig > +$ make flash.bin CROSS_COMPILE=aarch64-linux-gnu- > ATF_LOAD_ADDR=0x960000 > + > +Burn U-Boot to microSD Card > +=========================== > +$ sudo dd if=flash.bin of=/dev/sd[x] bs=1024 seek=32 > + > +Boot > +==== > +Set baseboard DIP switch: > +S17: 1100XXXX > + <snip> > 2.25.1 Link: [1]: https://github.com/Freescale/meta-freescale/blob/master/recipes-bsp/firmware-imx/firmware-imx-8m_8.9.bb -- andrey
