Banana Pi R3 mini........I'm lost

Banana Pi Router design BPI-R3/R3 Mini(MT7986)
81

I’m waiting to find out the next steps.

82

Just read the next section of the instructions i’ve posted

https://openwrt.org/toh/sinovoip/bananapi_bpi_r3_mini#installation

https://openwrt.org/toh/sinovoip/bananapi_bpi_r3_mini#installation_instructions_for_nand_done_via_lan_port_ssh

But just do it from serial and for bl2 se PS with mtd-rw

83

OpenWrt 24.10.5, r29087-d9c5716d1d

  • root@Home2:~# mtd write /tmp/openwrt-24.10.5-mediatek-filogic-bananapi_bpi-r3-mi ni-snand-preloader.bin /dev/mtd0
  • Could not open mtd device: /dev/mtd0
  • Can’t open device for writing!
  • root@Home2:~#

root@OpenWrt:~# cat /proc/mtd
dev: size erasesize name
mtd0: 00200000 00020000 “bl2”
mtd1: 07e00000 00020000 “ubi”

…for bl2 see PS with mtd-rw

  • OpenWrt 24.10.5, r29087-d9c5716d1d

  • root@Home2:~# cat /proc/mtd

  • dev: size erasesize name

  • mtd0: 00200000 00020000 “bl2”

  • mtd1: 07e00000 00020000 “ubi”

  • root@Home2:~#

86

Post is unrelated to my guidance…just recall my information about mapping mtd numbers to partition names

And atill without code tags…

I refer to this section in the openwrt wiki aka PS section

P.S.: in case write to MTD results in error, apply the following:

insmod mtd-rw.ko i_want_a_brick=1

87

  • opkg update

  • opkg install kmod-mtd-rw

  • insmod mtd-rw i_want_a_brick=1

  • mtd write archivo.bin bl2

It didn’t give any errors this time.

Still same error and still no code tags…

This is what I’m putting and it keeps going in an infinite loop.

You are right — that error is expected.

archivo.bin was only a placeholder in the example. The real command I used (and that works) is:

mtd write /tmp/openwrt-24.10.5-mediatek-filogic-bananapi_bpi-r3-mini-snand-preloader.bin bl2

After loading kmod-mtd-rw and running: insmod mtd-rw i_want_a_brick=1

the write to the bl2 partition succeeds.

So the error shown above is simply because the file archivo.bin does not exist, not because of an MTD or permission issue.

Thanks for pointing out the importance of mapping MTD names correctly and for the reminder about using code tags.

But you still not follow it…

For the crash you have to flash the phy firmware to the right ubi volume…

https://openwrt.org/toh/sinovoip/bananapi_bpi_r3_mini#remove_the_device_from_power_set_boot_switch_to_nand_power_up_and_boot_into_openwrt

Followed by

ubimkvol /dev/ubi0 -N en8811h-fw -n 1 -s 147456 -t static
cd /lib/firmware/airoha
cat EthMD32.dm.bin EthMD32.DSP.bin > /tmp/en8811h-fw.bin
ubimkvol /dev/ubi0 -N en8811h-firmware -n 1 -s 147456 -t static
ubiupdatevol /dev/ubi0_1 /tmp/en8811h-fw.bin

Possibly you have to delete partition 1 if you created with the other name before doing above commands

ubirmvol /dev/ubi0 -N en8811h-firmware

Solved: U-Boot loop caused by wrong EN8811H UBI volume name

The issue was not a broken NAND, OpenWrt bug, or temporary firmware loss.

The boot loop and crash:

  • Volume en8811h-fw not found!

  • [Airoha] read firmware from UBI failed.

  • Synchronous Abort

were caused by a wrong UBI volume name for the EN8811H PHY firmware.

I originally created the volume as:

  • en8811h-firmware

but U-Boot 24.10.x expects the volume name to be exactly:

  • en8811h-fw

Because of this mismatch, U-Boot could not load the PHY firmware and crashed during early boot.

:white_check_mark: Fix (booted into OpenWrt with NAND selected)

  • cd /lib/firmware/airoha

  • cat EthMD32.dm.bin EthMD32.DSP.bin > /tmp/en8811h-fw.bin

  • ubirmvol /dev/ubi0 -N en8811h-firmware 2>/dev/null

  • ubimkvol /dev/ubi0 -N en8811h-fw -n 1 -s 147456 -t static

  • ubiupdatevol /dev/ubi0_1 /tmp/en8811h-fw.bin

  • sync

  • reboot

:heavy_check_mark: Result

  • U-Boot successfully loads the EN8811H PHY firmware
  • Boot loop is gone
  • System boots normally from NAND
  • NAND and eMMC are both in a good state

Root cause: incorrect UBI volume name for the PHY firmware.

94

Now the NAND and eMMC are working. I’d like it to have the 8GB on the eMMC

What should I do now?

95

Hi everyone,

I’m trying to get 2.5Gb/s speed on my BPI-R3 Mini running OpenWrt 24.10.5.

  • PHY: Airoha EN8811H
  • Driver: mtk_soc_eth
  • Using Cat8 cables
  • Connected to a 2.5Gb/s switch

Right now, the link only reaches 1Gb/s, even though the hardware supports 2.5Gb/s. I tried using ethtool to force it, but it still shows 1Gb/s.

Has anyone successfully enabled 2.5Gb/s on the EN8811H with OpenWrt? Is there a driver update or workaround?

Any help or guidance would be greatly appreciated!

96

For 8gb there are many threads for each board…just read there. It is not recommended to increase rootfs to 8gb because it may break sysupgrade. Add an additional partition and mount it for data.

For speed 2500 i have no idea, you can look with ethtool what is advertised local and from remote side…
