Banana Pi M2 Berry won't boot

Recommended Posts

Armbianmonitor:

No matter which image I take (stretch/bionic; Bananapim2/Bananapim2ultra; 5.38/5.69) my Banana Pi M2 Berry with it's Allwinner V40 won't boot correctly. The attached screen stays off and the LED keeps shining red. I used Etcher 1.4.9 portable to copy the image to an 16 GB MicroSD.

 

It's worth mentioning that the Pi and the MicroSD work just fine if I'm running it with another distro, like the 2018-05-24-raspbian-jessie-preview-bpi-m2u-sd-emmc.img from the official website.

 

If I'm using the image Armbian_5.69_Bananapim2ultra_Debian_stretch_next_4.19.13, then I'm able to access the Pi via ssh. Yet, the screen won't work at all. As an interesting side effect, the Wifi of my notebook can't connect whenever I start my Pi with that image.. I guess the Wifi module of the Pi might jam the radio somehow. The armbianmonitor output comes from this image.

 

The image Armbian_5.69_Bananapim2_Debian_stretch_next_4.19.13 doesn't seem to do anything at all. It should actually work better, because the M2 Ultra has another SoC than the M2 berry.

 

What could I do to run it finely? Is the M2 Berry not supported yet?

nope.. it's csc only.. means no 'official support'

You can, but not in this section, but here: https://forum.armbian.com/forum/23-community-forums BTW. board boots, just HDMI is broken - fixed in 4.20.y+

Thanks for moving the thread.

 

I tried the old nightly Armbian_5.59.180823_Bananapim2ultra_Debian_stretch_dev_4.18.4 and HDMI works fine there. Wifi is still jammed, though.

 

Are any bugs known that might cause Wifi jamming?

Sounds promising. Is 4.20 stable enough to give it a try? Where can I get it?

 

@Mario Schmidt Dont give up ;)
The actual 4.20.6 image for the M2 Ultra does boot fine on the M2 Berry and HDMI/WiFi is working (tested console-server).
But it isnt directly downloadable at this time - you have to compile the image with the armbian-build-system:
https://docs.armbian.com/Developer-Guide_Build-Preparation/

 

A  small virtual (or real) Ubuntu-18.04-x64-Mini-Server and some commands and you are up and running for compiling the DEV-image with 4.20.6

Hi, Mario:

 

I have a BPI M2U, but it is always stick with a red led once i try to boot with an SD Card running any Armbian image (including the one that you shared -> Armbian_5.74_Bananapim2ultra_Debian_stretch_dev_4.20.6). The board power red led truns on and the board don't get any IP address on ethernet port (so, no SSH).

 

The only way that the board boots is using any original image from BPI (http://wiki.banana-pi.org/Banana_Pi_BPI-M2U#Image_Release), wit kernel 3.10.

 

Any ideas? what can i do to booth with an Armbian image? is it something with the u-boot? how can i update the u-boot with an original BBPI image to them boot with Armbian?

 

Regards,

 

Mauricio Florez M.

Hi Martinayotte:

 

I followed your advice from another topic and used the Serial Debug output with a USB-TTL Serial dongle. This is my output:

So, as you can see the board is stick while booting the kernel. Any ideas to solve this problem?

 

By the way, this is R40 BPI M2U.

as you did see in the TTL-log armbian does bring its own u-boot and the u-boot does boot, but there are no cpu-frequencys and no temperatures available :(

 

I compiled with the armbian-build-system the Image for the BPi M2 Ultra and it does boot fine on my BPi M2 Berry:

Please, change /boot/armbianEnv.txt to have "verbosity=7" and "console=serial", you will then get more details after kernel been uncompressed ...

Hi again martinayotte:

 

I followed your advice, and booted with "verbosity=7" and "console=serial", below it is the output:

 

the good news is that it does start loading the kernel but the bad news is it stops at [    7.003054] mmc2: new high speed SDIO card at address 0001

This MMC2 is for the WiFi, maybe the AP6212 is defective ...

If you don't mind loosing WiFi, maybe you can decompile DTB into DTS, changing MMC2 node "status" to "disabled", and then recompile DTB from this edited DTS and reboot !

With luck, boot will maybe go further ...

Dear martinayotte:

 

I decompiled the DTB file to sun8i-r40-bananapi-m2-ultra.dts, then changed mmc@1c11000 status from "okay" to "disabled". That was the issue and once changed the problem was solved. Now Armbian runs 100% perfect.

 

Nevertheless, as i want to use buster instead of stretch, everytime that is use apt-get install update / apt-get install upgrade, the file is changed again and the board stop booting again.

 

So, is there any way for you to change update the code on the build system like a patch to avoid futher problems?

 

PD: I already checked the guidol DTB file and for berry that file was ok with the status for mmc@1c11000 = "disabled", so, that is why the problems was just on M2U and not on Berry.

 

Thanks you very much,

 

Mauricio F.

No, I've an M2U and don't have the issue, as I've said it is probably that yours has a defective AP6212.

You can avoid DTB updates using "apt-mark hold linux-dtb-dev-meson64_5.94_arm64.deb" for example.

Dear martinayotte,

 

I found a big issue, i followed you advice to disable MMC2, nevertheless, if i do that WIFI still works but Internal EMMC mmcblk1 (8GB) doesn't work. So, as i want to use install Armbian in that memory i tried again enableing mmc2 and leaving the board alone to boot, my surprise was that after a lot of time, the board boots and fdisk works and detects mmcblk1, but if i try to wirte anything to emmc it crashes.

 

I guess that on my board mmc2 is not wifi, instead of that it is EMMC memory, but there is a conflict while wirting and that is why the boot time is so long.

 

I tried the same with original banana images and there is no problem there, i can write mmcblk1 without any issues.

 

attached is boot log from Serial TTL and dmseg both in armbian and Seria TTL from bananama img.

 

Any help will be appreciated, Thanks.

Hi again, 

 

I reaally don't know what is happening.

So, if MMC1 is the flsh EMMC memory on both, and MMC2 is WIFI, why if i disable MMC2 on Armbian stops MMC1 too?

I found the following:

 

When both mmc1 and mmc2 are enable, the following error shwos for emmc2.

 

[  170.393893] brcmfmac mmc2:0001:1: Direct firmware load for brcm/brcmfmac43430-sdio.sinovoip,bpi-m2-ultra.txt failed with error -2

but when mmc2 is disable from DTB, the error pass from emm2 to emm1.

Does it hav any sense?

 

the problem as you said is with brcm/brcmfmac43430 driver for AMPAK AP6212 - SDIO (02d0:a9a6) BCM43430 (WiFi/BT 4.0) (1T1R 802.11bgn).

 

Thanks again, Regards,

As I remember on some other board there was a error like this, because they changed in production the type of the chip (in the past ram chip) but maybe they changed the emmc chip.

maybe you could compare with other users board.

my berry hasnt a emmc.

Hi Martinayotte and Guidol:

 

So many thanks for you help and effort.

 

I have been deepth analizing the DTB file for BPI M2U and the board schematic from BPI at https://drive.google.com/file/d/0B4PAo2nW2KfndUZobUNSQ0YtalE/view?usp=sharing, and i'm pretty sure that the DTB file was developed to have eMMC like mmc2 and WIFI like mmc1. Nevertheless, the board boots and the kernel load eMMC like mmc1 and the WIFI like mmc2, (i don't know why).

 

I rewrite the bus width to 4 for SD (mmc0) and Wifi (mmc) and width to 8 for eMMC (mmc1) and now the board boots faster and does not crashes when i type fdisk /dev/mmcblk1 like it was before. So now, the board is working perfectly with armbian loaded from SD card, but i'm having problems to create a partition to mmcblk1.

 

As you can see on the attachd image below, the fdisk -l, list the mmcblk1 with the right size (7.3 GB), them i'm creating a new partition and writing the partition table without any issues, but once done,  the new partition never gets to the disk, and fdisk -l shows the disk like if was before. Of course, whithout a partition i can not format the eMMC and can not use nand-sata-install.

 

This only happens with armbian, because with bananapi images there was no issue to create the partition and save it to the disk like mmcblk1p1. 

 

Even worse, if the eMMC disk has been partitioned and it is not formatted again, i really don't know why armbian (kernel) can not see that partition that was done with BPI images if it is Ext4.

 

Regards,

 

Mauricio F.

Hi Guys:

 

I decided to start again from the begining, so, modified DTB file to disabled MMC1 (WIFI), and just leaving the MMC2 (eMMC 1c11000) enable "okay".

 

        mmc@1c11000 {
            compatible = "allwinner,sun8i-r40-emmc\0allwinner,sun50i-a64-emmc";
            reg = < 0x1c11000 0x1000 >;
            clocks = < 0x07 0x22 0x07 0x6d >;
            clock-names = "ahb\0mmc";
            resets = < 0x07 0x0a >;
            reset-names = "ahb";
            pinctrl-0 = < 0x12 >;
            pinctrl-names = "default";
            interrupts = < 0x00 0x22 0x04 >;
            status = "okay";
            #address-cells = < 0x01 >;
            #size-cells = < 0x00 >;
            vmmc-supply = < 0x0c >;
            vqmmc-supply = < 0x0c >;
            bus-width = < 0x08 >;
            non-removable;
            phandle = < 0x3d >;
        };

 

Doing that, now i can see the device partition mmcblk1p1 with fdisk -l, but when i try make any change wth fdisk or format de partition, the console stops (conflict).

 

[    4.611521] mmc1: new DDR MMC card at address 0001
[    4.617642] mmcblk1: mmc1:0001 8WPD3R 7.28 GiB
[    4.623098] mmcblk1boot0: mmc1:0001 8WPD3R partition 1 4.00 MiB
[    4.629997] mmcblk1boot1: mmc1:0001 8WPD3R partition 2 4.00 MiB
[    4.678318]  mmcblk1: p1
[    5.550366] sunxi-mmc 1c11000.mmc: data error, sending stop command
[    6.553221] sunxi-mmc 1c11000.mmc: send stop command failed
 

So, if it is not a conflict with the Wifi module as it is disabled, what else is doind this conflict? by the way, if i change the bus width to 4, and that way the errors above are no longer show on dmesg even as eMMC is correctly detected, but again it stops when trying do write anything to the flash memory.

 

Kernel is not the problem as fdisk works well to creata a partition on a SATA external drive and The eMMC memory is not damaged as it works perfectly with the original BPI images, so, do you have any ideas on how to solve this mistery?

 

I already cheked the schematic again, and the pins are ok, pins = "PC5\0PC6\0PC7\0PC8\0PC9\0PC10\0PC11\0PC12\0PC13\0PC14\0PC15\0PC24";

vmmc-supply = < 0x0c >; to vcc-3v0 is ok too.
vqmmc-supply = < 0x0c >;  to vcc-3v0 is ok too.

 

I don't have any idea where to look. Any help will be much appreciated.

 

Thanks and best Regards,

 

Mauricio F.

Holy Mother of God, i found the problem.

 

I found on web blog that for eMMC as they are DDR they need a drive-strength of 40 instead of 30 like it was.

 

            mmc2-pins {
                pins = "PC5\0PC6\0PC7\0PC8\0PC9\0PC10\0PC11\0PC12\0PC13\0PC14\0PC15\0PC24";
                function = "mmc2";
                drive-strength = < 0x28 >; => equual to 40 in decimal
                bias-pull-up;
                phandle = < 0x12 >;
            };
 

So, i guess that now somebody has to update the DTB with a patch.

 

Thanks.

 

Mauricio F.
