NEW BPI-R3 - How to load image on eMMC

[gilmotta (Gilson Motta Jr)]

Hello All,

I received my R3 board and I would like to start loading the software. Where can I find instructions to load the software on the eMMC? The section “Getting Start” from Banana Pi BPI-R3 - Banana Pi Wiki is empty . I have SW1 set to 1 and SW2 set to zero. I downloaded the image from Google Drive mtk-bpi-r3-image-20220601.zip - Google Drive

What I need is step by step instructions how to load the software on the eMMC.

Thanks much.

I appreciate your help.

thanks, Gil

You have to get spim-nand/nor bootable and flash from this.

https://wiki.fw-web.de/doku.php?id=en:bpi-r3:uboot

But i’m not sure the image is emmc capable

[gilmotta (Gilson Motta Jr)]

Thanks for the tip. I would need instructions for the following:

BPI-R3 u-boot

• create bootable sdcard (How?)
• bootup with sdcard and with bl2+fip for spi-nand on card or usb-stick (what is bl2+fip? I need more details)
• flash bl2+fip to spi-nand (How?)
• powerdown and change sw2 and sw6 to emmc
• bootup from spi-nand and flash gpt+bl2+fip to emmc (how to flash gpt+bl2+fip?) I need a video or a step by step guide please
• optional: load a linux-kernel with initrd and emmc-fdt to unpack rootfs+kernel to emmc rootfs
• change back sw2 and sw1 to do next boot from emmc (looks like that you go from SD to SPI/NAND to eMMC, this is not straight forward for me as I am not familiar with these tools)

I appreciate your help. I will pay a bounty to anyone who can create a step-by-step guide and publish to the community.

thanks, Gil

Bl2 and fip are created by build.sh in atf branch. You can download them from github releases too.

The build.sh on my atf branch contains a createimg function to create an sdcard image (do not change device). Compile uboot first,then atf then do createimg. Flash this image to sdcard (dd command in linux).

With this you can boot the board if bootswitches defined for sdcard boot (see table on page or board).

Steps for flashing spi-nand and for emmc are described in the sections of uboot page above.

R3 is not end-user ready yet,i’ve managed to get it booting from sd/spi-nand/emmc and wrote steps down and working to get other things working.

[gilmotta (Gilson Motta Jr)]

Hello Frank, Thanks for your help. I will try to follow the steps you wrote above, let’s see how far I can go. I still have thousands of questions, Are you booting OpenWrt? My end goal is to run OpenWrt. Thanks, Gil

[frank-w]

No,i’m working on mainline linux,but daniel does openwrt support in his staging tree

[BPI-R3] information

I started working OpenWrt support for the R3 and got most things working. Drivers still need more love for SFP cages to be fully functional, but apart from that things look pretty good already. See r3-mt7986 branch of my staging tree on git.openwrt.org: https://git.openwrt.org/?p=openwrt/staging/dangole.git;a=shortlog;h=refs/heads/r3-mt7986 Feedback and questions are very welcome!

[gilmotta (Gilson Motta Jr)]

This is where it is becoming difficult for me to follow. So, Can I use your uboot with his OpenWrt? I think someone needs to write a guide we have too much information that is scattered.

[frank-w]

As i said we currently trying to getting things working,so i write down steps in shortest way due to time…i wonder you have got a board in this early phase.

If all is working we can expand the guides for end user.

Why using my uboot with openwrt? Openwrt has its own (based on my patches,more cleaned by daniel)

[gilmotta (Gilson Motta Jr)]

Hi Frank,

I received an R3 board. I want to load OpenWrt. Should I talk to you or Daniel for help with OpenWrt? I would pay for your time or whoever helps me to bring this up. I want to launch OpenWrt and connect some devices to the R3 ethernet ports, get IP address, set DNS, basic networking stuff and after that I want my devices to transfer data back and forth from wire to wire and wire to WiFi an vice versa…

Thanks, Gil

[frank-w]

For openwrt daniel is the better person. We have not yet got sfp slots working. Maybe you can help here.

The rj45 ports working so far,so it’s only bootup system and configuration. Afair network needs some tuning (remeber some retransmitts in iperf),but it is usable.

[gilmotta (Gilson Motta Jr)]

Hello Frank,

I am not able to boot OpenWrt on my R3 board. Daniel sent me his image file and I was able to boot one time but then I tried to boot my build and after several failures I went back to Daniel’s build and it is failing to boot that also.

Below is the serial port dump, can you please take a look and see if you recognize anything and if you can tell me how to fix? I shared this with Daniel and he is looking into it also. I just thought that maybe you could add some value to help us.

All the switches are in the correct position to boot from the SD card. Thank you!

Seems like gpt on your sdcard is broken,bootup itself is working,but access to it brings errors

[gilmotta (Gilson Motta Jr)]

is there a way to verify the SD card partitions when it is writing or after writing? something like a CRC error check or something that will compare the .img file with the contents of the SD card?

Also, Can I make the SD card safely read-only?

[frank-w]

You can read the content of card back to an image (same size!) And compare this with original image using a hash algorithm (md5,sha256,sha512)

Imho read only is not possible as you may need write access to it for booting the system correctly

Thank you! I will see what I can do. This issue is driving me crazy!

[frank-w]

Just flash image to sdcard again is easier

[gilmotta (Gilson Motta Jr)]

Hi Frank, I already did it so many times but there is something that isn’t working right in my case. I need to come up with a way to consistently verify the dd command is doing its job. This is not going to be a hobby, I am a garage company but I am creating a product that will require consistency in the assembly process. I will also need to protect the boot loader against data corruption. I will need your help to protect the boot and the OS in the field. I will not be able to reprogram boards in the field.

[frank-w]

Make sure switches are really snapped in. We noticed that sometimes they do not completely connect

The only way i see is using sd readonly is booting the rootfs from another storage or using a.ro rootfs with overlay-root in ram only…only leave bootchain till uboot on sd. This does not require write access if no env needs to be written in uboot.

[gilmotta (Gilson Motta Jr)]

Hello Frank, After pushing the SD card into the slot with force, I was able to reboot again. The guys at Banana Pi aren’t taking me seriously and I am starting to get upset. I am designing a product that needs reliability this is not a hobby for me.

I sent an email to Banana and they replied with the following:

Hi, Gil ] Are you using our image? Does it work properly? Banana Pi products must use the Banana Pi image.Please use our image when you Burn-in board.

** I asked them for the instructions but they never gave me. I opened their zip files and I see a number of .bin files that I don’t know what to do** I am not happy with their support. It took me two weeks to be able to get just a part number for one simple connector. unbelievable!
