Banana Pi M3 Boot from EMMC

bahtiyar57 · February 3

I used armbian-config to set up boot from EMMC.

Then I run

dd if=/dev/zero of=/dev/mmcblk0 bs=1024 count=2048

And re-partitioned my SD Card.

Rebooting with or without SD Card not possible.

Gunjan Gupta · February 4

is there any output on serial console?

Hi

I'm running into the same issue, this is the output i get from the serial

<\r><\n>
U-Boot SPL 2024.01-armbian (Feb 10 2024 - 01:33:08 +0000)<\r><\n>
DRAM: 2048 MiB<\r><\n>
Trying to boot from MMC2<\r><\n>

spl: mmc init failed with error: -95<\r><\n>
SPL: failed to boot from all boot devices<\r><\n>
### ERROR ### Please RESET the board ###<\r><\n>

I got no idea what to search for in this case, also somehow my emmc is mmcblk2 instead of the mmcblk1 that it's refered to in every source i found so far

I tried it in so many ways. Other images can be started from the emmc without any problems. It would be very nice if any one could help us.

Yesterday I had same problems with my on SD Card installed Armbian. It won't boot. After a few failed attempts to boot, it did after all.

Surprisingly not from the SD Card. It booted from EMMC, where was a clean Armbian installation flashed.

After reboot it was no more possible for me to repeat this.

What other images were you trying Bahtiyar ?

I'm intending to use the banana Pi for a 3d printer and EMMC booting is the last thing holding me back.

Can't find that image anywhere and no matter what i try (even the banana pi supplyed ones) refuse to boot into emmc. When going into the U-Boot shell with a SD-Card plugged in i can get this env

Also i can access the emmc once booted

@Gunjan Gupta Do you have any idea where to go from here or where to find more info on how to maybe get it booting from emmc ?

O to the o · May 20

Results of today:

I found no image that would let me boot from EMMC without the micro SD, but when i edit the armbianEnv on the SD to point to the UUID of the EMMC partion with installed os it boots from the EMMC. So my conclusion is that i need to build my own U-Boot.bin to get around the poweron issue with the emmc.

bahtiyar57 · May 25

Did you build a custom U-Boot bin?

O to the o · May 25

So far no, but I'm reading up on it and plan to

O to the o · May 26

So I figured out how to test uboot.bin's with the fel mode, but so far couldn't build my own uboot for the a83t. Also i dug around in the image and it seems like the banana pi m3 images doesn't have the uboot for the a83t (might be wrong there)

O to the o · May 29

Now looking at the DTS for the banana pi M3 (sun8i-a83t-bananapi-m3.dts) turns out the emmc is mmc2 not mmc1. Got no idea what mmc1 could be but it uses the wi-fi's power sequence

I remember that I recorded the image on the SD card using "dd" and the standard procedure at the first start.
Then, on my desktop machine, I started "mc" and connected to the device via SSH.
I copied the image file to the home directory.
Then I wrote it to "/dev/mmcblk2" using the "dd" command.

Thanks @going, i tried your image but it didn't work for me. Can you explain the copy process a bit more ?

I used this command dd if=xxx.img of=/dev/mmcblk2 bs=10M to copy it

dd if=YYY.img of=/dev/mmcblk2 bs=1M; sync

On my device, a rather old image is recorded in EMMC.
I'll check tomorrow how the new one will work.

One more nuance.

These sections are completely empty for me:

Yes, I confirm. U-boot does not support (not configured during compilation) booting from EMMC.

Today I will fix it for Armbian and for my image.

Wait a bit.

Mind elaborating a bit what needs to be changed about the uboot to make booting from EMMC possible ? I've been poking in the dark for a few days now, learned a bit and really like to know what i'm missing

The SPL must supply power for the chip to work.
He doesn't seem to know where to go.

Unfortunately, I don't remember how I did it in the old u-boot. I have no records left, which means that everything was very simple.
But the code has changed and additional settings may be required for the default configuration.

We'll have to wait a bit while I test my changes.

Thanks, i looked at the scematics doesn't seem like there is a voltage select that is just for the emmc

@going

it's not a good solution for me to use a pre-build image. Is there an option to make it work with any image?

Hello.
Are we talking about starting the OS booting from eMMC?
Today I can only give some recommendations in theory.
My problem is that the BPI-m3 appeared to me in 2013.

I have successfully completed and completed one project on it.

But I forgot how I did it. And I didn't keep all the old images.

Should I lay out the theoretical foundations?

Today I'm trying to figure out the new u-boot code.

And make the assembly within the framework of the Armbian assembly system so that the image can be loaded from both the SD card and the eMMC.

The whole problem lies in the "configure u-boot correctly" plane.

O to the o · Monday at 09:03 AM

Thanks that's what my conclusion also was, I'll search my old backup drives for an old image that still could boot from emmc. Me poking at the uboot config won't do much good. If you need someone to test something ask
