BPI-R3: bricked SPI-NOR, looking for factory SPI_NOR image

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

Hello, an update from within OpenWrt made from SPI-NOR booting impossible. I’ve tried to flash SPI-NOR several times but apparantly I cannot get hold of a good file.

From OpenWRT I saved the mtd[0-4] files, can can boot from SD using an ImmortalWrt image.

I’m looking for the factory SPI-NOR image for BPI-R3 so I can

mtd erase /dev/mtd0 dd if=mtk-bpi-r3-NOR-WAN1-SFP1-20220619-single-image.bin of=/dev/mtdblock0

Can anyone provide me with this file? Building gives an error, looking into that now.

current mtd contents: root@ImmortalWrt:~# cat /proc/mtd dev: size erasesize name

  • mtd0: 01400000 00010000 “fit”
  • mtd1: 00a80000 00010000 “recovery”
  • mtd2: 00080000 00010000 “fip”
  • mtd3: 00080000 00010000 “reserved2”
  • mtd4: 00040000 00010000 “u-boot-env”
  • mtd5: 00040000 00010000 “bl2”

while the backup provided me with:

jstoorvo@HiGole2:~/Downloads/bananapi> cat backup/spi_nor/readme.txt

  • 262144 28 OpenWrt.mtd0.bin → BL2
  • 65536 28 aug 22:19 OpenWrt.mtd1.bin → u-boot-env
  • 720896 28 aug 22:19 OpenWrt.mtd2.bin → Factory
  • 524288 28 aug 22:20 OpenWrt.mtd3.bin → FIP
  • 14680064 28 aug 22:21 OpenWrt.mtd4.bin → firmware

I’m looking for the file mtk-bpi-r3-NOR-WAN1-SFP1-20220619-single-image.bin as referenced in Getting Started BPI-R3 | BananaPi Docs

Did you try to change Bootstrap switch to SD card and in the u-boot menu use option 7. Install bootloader, recovery and prodution to NAND? Similar option to eMMC is when you switch the bootstrap switch to use NAND memory.

Old screenshoot from BPI-R4.

I do not have this usb/uart cable yet, i’ve been using ssh only. I’ll try to get one as soon as possible. But it’s not my NAND that’s corrupted but my NOR.

I can boot from SD card however!

The reason why I’m not touching my NAND yet because I cannot boot from NOR anymore…

But thanx for your comment!
