Hello.
Is there any difference with installing OpenWRT on integrated eMMC of compute module (CM3+)? I tried lastest rpi-3-ext4-factory.img.gz
and
rpi-3-squashfs-factory.img.gz
ext4 seems to do nothing after power up.
Squashfs show rainbow screen and then doing nothing also.
I also tried to copy start.elf fixup.dat and bootcode.bin from lastest Raspbian with no luck
What i doing wrong?
see the bottom of this document ( and use this method to swap / compare oem vs openwrt filesystem structures as CM is technically not supported, and yes... i'd imagine some swapping of boot/start bins might be necessary )
Thanks.
Solution:
copy bcm2710-rpi-cm3.dtb from raspbian boot to openwrt boot partiotion.

LAN9514 schematic is same as on reference datasheet.
Could someone help me with this issue? Thanks.
anti-otg parameter you need in config.txt ( or similar )?
Solution:
Dont copy bcm2710-rpi-cm3.dtb from raspbian. Probably it does not contain correct device info. I just renamed bcm2710-rpi-3-b-plus.dtb to bcm2710-rpi-cm3.dtb and lan9514 and all attached USB devs seems to be ok.
Sure i need to make my own dtb file related to my hw config. This will be the next step
