Hi Everybody, is there any update on booting EMMC with NANOPI K2?

so we are at the same point as before, boot from SD and rootfs from EMMC is working, boot and work from EMMC isn't. Did I understand this correctly?

now I'm confused, the last statement I got was, EMMC BOOT on a NANOPI-K2 is impossible. Is this information outdated? is there a chance to boot from EMMC directly? br wikrie

Thanks @ martinayotte I will try it and give you a feedback !! And it works !!!! Booting from SD and working from EMMC, that is half the way I want! But at the end much more than nothing!!!! 1mil Thnaks @martinayotte wikrie@nanopik2:~$ mount | grep mmc /dev/mmcblk0p1 on / type ext4 (rw,noatime,nodiratime,errors=remount-ro,commit=600) /dev/mmcblk1p1 on /media/mmcboot type ext4 (rw,noatime,nodiratime,errors=remount-ro,commit=600,x-gvfs-hide) /dev/mmcblk1p1 on /boot type ext4 (rw,noatime,nodiratime,errors=remount-ro,commit=600) wikrie@nanopik2:~$ sudo blkid /dev/mmcblk0p1: UUID="8c928f56-9de2-4e7b-91ab-2144bb0e42d3" TYPE="ext4" PARTUUID="567b6072-01" /dev/mmcblk1p1: UUID="bbeb1faa-8bba-463c-a3e2-3722d68654af" TYPE="ext4" PARTUUID="567b6072-01" br wikrie

Hi Folks, I try to run the following issue , boot from SD and use EMMC for rootfs. But I cannot get it to boot, is there any tutorial how to handle it? br wikrie

Hi Folks, seams that there is no Solution for this issue, so the cost for the emmc was a little waste of money. If anybody has any idea please let us know, we will test / try all. bet regards wikrie

Hi Everybody, I try to follow your conversation but I cannot see where to help or to test anything, seams to be a bigger problem with the boot from EMMC. So I'm not sure if it helps in any case but I extract the working boot parition from the existing NANOPIK2 image and if anybody like ot could be downloaded from: https://my.pcloud.com/publink/show?code=XZKKTa7ZnglxwkfmdHHoR35AbYpwW0QYTQBk And I also attached it to that post. If I could test anything please let me know. br wikrie boot-emmc-k2.zip

Sorry for my meretriciousness, you are totaly right, and I keep my fingers cross that there will be a solution some day. So far I could try to find out the different between booting DT from Vendor (but no USB) and the DT from us here, maybe I can see the reason why this DT is not booting up. So have a nice day and it would be great to hear from you again. br wikrie

Any new Advise? @TonyMac32 @martinayotte @Igor @Neil Armstrong

So I was able to run the nand-sata-installer and my emmc flash drive was correctly written, then I also run the platform_installer.sh with the modification shown above. But still the K2 only boots from SD if I try to boot the K2 with emmc only I just see a black screen, I do not see any mistake and/or problem! btw I change the advise from above. $2 to /dev/mmcblk1 that would be offset my SD Card ?? for that reason I change it to mmcblk0 ... but still blakc screen with emmc. any advise?

as I wrote bevor I cannot access the emmc in any way from the nanopik2, I just see the emmc. but everytime I try to access it I get I/O Error. I will try to start this from a clean system. Maybe I do some mistake in the meanwhile. BTW is the DT compiler version important? I use 1.4 insteaf of 1.4.7-3. SO I will try it again and send over my feedbacks.

If I could test something with my emmc please tell me what and I will do!

I order the same and the delivery for that item was strange, because it was send as per lastname, that means in Germany you have to sign for the delivery, this is mostly used for letter from law or something else important, not for a 20 bucks china delivery ... :-) so if you get a notification to catch it by signing dont worry it is the emmc card from china!! :-) Thatsthe reason why it costs 8 € delivery.

Thanks I will check it tomorrow, sleep well!
