Reboot to emmc/nand [Solved]Failed due to no env partition

#1

Hello,

I just installed coreelec to a mecool m8s pro plus (S905x) and copied gxl_p212_2g.dtb to dtb.img.
I tried to reboot android from internal by selecting boot from emmc/nand but the box rebooted to coreelec.

after manually trying to launch rebootfromnand im getting this error:

CoreELEC:~ # /usr/sbin/rebootfromnand

Error: environment not initialized

Finally got time to get back to this.
Turns out the tv box labeld as mecool m8s pro + has a s905w chip…

Hello, I have the same problem on mxq pro 4k s905x/1gb (android 6). Used dtb gxl_p212_1g.
Box rebooting to coreelec all the time.
Also got this error:

Cannot parse config file ‘/etc/fw_env.config’: Invalid argument
Error: environment not initialized

CPU-Z and AIDA64 on android show that this box is gxl p212 so what’s the problem?
To be sure, I checked other dtbs like: p200, p201 - box freezes on AMLogic logo.
Only p212_1gb works.

Same problem on Tanix TX3 Mini - H 2/16. Tried gxl_p212_2g, gxl_p281_2g and few more… It boots and works normally but I cant reboot back to Android, it reboots back to CoreElec every time. Pulling out sd card is the only way to use Android. Any fix?

It won’t work on devices that have no env partition, theres no workaround for this.
