OpenWRT for Banana Pi BPI-R4 8GB device

[KlausStoertebeker]

Hello to the forum,
the Banana Pi BPI-R4-Router is sold in two versions:
4 GByte RAM
8 GByte RAM
But in the OpenWRT Firmware Selector you can only download versions for the 4 GByte version.
Unfortunately I'm not a programmer, so I would be very happy if someone could compile OpenWRT 24.10.3 for the Banana Pi BPI-R4 8 GByte RAM-Router and make it available via the OpenWRT Firmware Selector?
Thanks in advance
"Klaus"

Hello frollic,

thank you for your prompt reply. However, the download links on the page

[OpenWrt Wiki] Sinovoip BananaPi BPI-R4

unfortunately do not lead to the desired OpenWRT versions:

For the factory image (https://downloads.openwrt.org/releases/ 24.10.2/targets/mediatek/filogic/openwrt-24.10.2-mediatek-filogic-bananapi_bpi-r4-sdcard.img.gz) is a 24.10.2 version for the 4 GB version of the BPI-R4.

And version 24.10.3 (https://downloads.openwrt.org/releases/24.10.3/targets/mediatek/filogic/openwrt-24.10.3-mediatek-filogic-bananapi_bpi-r4-sdcard.img.gz) is unfortunately also not for the 8 GB version, because I installed that yesterday and successfully put it into operation. However, only 4 GB of available RAM is displayed there.

However, I found a bootloader eMMC version for the 8 GB version.

I would like to install it via U-Boot, but I don't know how to do that.

I guess I have to do it via TFTP – but how?

where does it say you need an 8GB image ?

@KlausStoertebeker

However, only 4 GB of available RAM is displayed there.

you did read the page I provided, right ?

[KlausStoertebeker]

Yes, I have read the page you provided. And there you can read that the bootloader that frank-w created for the BPI-R4 was NOT tested with OpenWRT. I also tried some other bl2.img from that page marked for the 8 GByte version - also without success.
And if I boot from the stock image provided by the OpenWRT Firmware Selector it detects only 4 GByte of the installed 8 GByte of DRAM.
So, to answer your question: YES, I need an 8 GByte image to use the full power of my 8 GByte BPI-R4. And I think I'm not the only one...

I think you are:

BPI-R4-8G can`t use 8G RAM

you need to flash patch bl2 img for BPI R4 8GB The second option works with any OpenWrt version and allows to use the full 8GB: I used the official OpenWrt Firmware Selector and picked the latest stable release, 24.10. After selecting the packages I needed, I wrote the image to an SD card and used it to install OpenWrt to the NAND using U-Boot, and from NAND to eMMC. This results in OpenWrt 24.10 being installed to eMMC (also on SD and Nand) but initially, only 4GB of RAM is detected. To fix t…

[Banana Pi R4 - 8GB RAM] No Internet Access After Installing bl2_emmc_8g.img

Hello everyone, I’m using a Banana Pi R4 with 8GB of RAM, and I’ve been trying to get OpenWrt to properly recognize all the available memory. To achieve this, I installed the BL2 patch that includes the specific bl2_emmc_8g.img for the 8GB version. After flashing the bl2_emmc_8g.img to the eMMC, OpenWrt boots correctly and shows 8GB of RAM, but from that point on, I have no Internet access, even though: The PPPoE connection comes up successfully. I get a public IP address assigned. ip route…

Disregard all I've written - they sold me a 4GByte version...

I also tested the openwrt 24.10.x with the bl2-image from frank_w.
8GB RAM is recognized.
But my fan is not running on the 8GB RAM board.
Did someone have the same problem?
