Support for Banana Pi BPI-CM4? #15
Comments
I am creating an H616 based image using the Armbian system. After this image, some hardware using Armbian images will be easier to port again. |

There are btw third party images for the BPI-CM4 available, see: https://wiki.banana-pi.org/Banana_Pi_BPI-CM4#Armbian @ThomasVon2021 Just wondering if that would mean your image will support this banana chipset as well? So anyway, do you think I can try to do a estimated bet by buying the banana pi cm4? Ps. I did bought your Blikvm Pcie card. So in theory hardware wise it should be compatible. Assuming you used only the first hdmi pin connector. (BPI-CM4 only support 1 hdmi instead of 2 hdmi connections with the Raspberry Pi cm4) |
Yes or no? Should I try to order the BPI-CM4? Assuming the new image will support it? |
The new mirror is launched with an Armbian system based on the H616 chip. |
Uh ok.. sure, but the Banana Pi BPI Compute Module 4 is using the Amlogic A311D chip. But hopefully it will support that chip as well as you try to mention earlier I guess. What do you mean with "New mirror is launched"? |
Hmmm I think I will just buy a Rasp CM4.. That works at least. EDIT: Nevermind, I can't buy a Raspberry CM4 anymore.. It's ALL SOLD OUT! |
We have created a new hardware based on H616, called blikvm V4, which is still under testing. You can join Discord to see more information. |
But I already bought Blikvm Pcie version v3.. Which needs a CM4 module... I really think we are still talking past each other. I want to use a Banana Pi BPI inside the Blikvm Pcie card. Unless this card isn't shipped yet, you want to sent me the v4? See order number: 8138090434501280 |
The PCIe version is designed specifically for CM4 and cannot be replaced with other modules. Because different chip pin definitions are different. |
Maybe you should better look into the Banana Pi BPI-CM4 ... It's pin compatible. It's compatible with cm4 from raspberry. This whole github issue is about to support that module, the pin layout isn't the problem at all. It's only a different cpu chip you might need to support in the image. |
So in order to have HDMI input, we use CSI, so far so good. CSI is actually supported by the Banana Pi BPI-CM4 as well.. but only 1 port (CAM1). And the 2nd CSI (CAM0) is not connected. So I hope you are not using 128-138 pins for CSI. But instead you use one of the ports in the pins 115-141? EDIT: We talked on the chat (Discord), be we sorted it out. CSI is connected to CAM1. Which is luckily pin 115 until 141, since CAM0 is not connected on the Banana Pi variant. |
Small update, I received the Banana PI CM4 module. I first tested the default Ubuntu Mate provided image from Banana Pi, which is booting from SD card. SO far so good, next will be trying to boot the BliKVM image from this hardware. Finally, I need to try to boot the image eventually from the SD card inside the BliKVM PCIe hardware. |
I think you need build blikvm software on a armbian os or Ubuntu Mate. You can refer to https://github.com/ThomasVon2021/blikvm/blob/master/dev-readme.md. If you have any questions, we can discuss them at any time. |
I think so as well. Raspberry Pi OS Lite is actually already Debian. But it might need the additional linux device trees files. That's it. |
If you use Armbian, it should be relatively smooth. Currently, I have been completely successful in using Armbian on H616 |

Sorry, I missed this message. I'll ask my hardware colleague for a response later. |
You need fan、oled、atx gpio number, right? |
I need the Banana Pi CM4 GPIO pin numbers as a Linux device tree file. In order to use ArmbianIO. ArmbianIO is used by BlikVM (which I hope you know). Therefore, the following file also need to be extended for Banana Pi CM4 as well: https://github.com/ThomasVon2021/blikvm/blob/master/third_lib/GPIO/armbianio.c#L55 (if you know what the int values are in the array for Banana Pi then I could also create a PR upstream project). And you are correct, without GPIO.. the fan, oled, atx but also simple things like a LED will NOT work... And blikvm software will not start. |
Banana Pi has released a wonderful BPI-CM4 hardware module compatible with the Raspberry Pi cm4...
Could you verify if your image works on this device? If not. Would you please consider supporting this nice piece of cm4 hardware as well with your images?
