BPI-R4 Openwrt 21.02 Build

Banana Pi Router design BPI-R4/BPI-R4 Pro(MT7988)
1

I am going to build the BPI-R4 Openwrt NAND image manually as I consider building the R8169 driver for RTL8125 module.

Does anyone know:

  1. Is BPI-SINOVOIP/BPI-R4-OPENWRT-V21.02 the source code of the official images in Banana Pi BPI-R4 | BananaPi Docs?

  2. Continue, if so, git clone it and run “make” directly to generate the NAND, EMMC & SD images like the ones provided on above official site?

  3. Continue, if not, how can I generate the NAND, EMMC & SD images like the official ones?

  4. Two other BPI-R4 BSP repos are found. Do they build uboot, kernel and pack them into Openwrt eMMC image only?
    BPI-SINOVOIP/BPI-R4-bsp-5.4
    BPI-SINOVOIP/BPI-R4-bsp-6.1

Thank you.

  1. GitHub - BPI-SINOVOIP/BPI-R4-OPENWRT-V21.02 the OpenSource MT76 wifi driver OpenWRT BSP.
  2. make, it will generate one whole nand image. it will include all.
  3. GitHub - BPI-SINOVOIP/BPI-R4-bsp-5.4 , GitHub - BPI-SINOVOIP/BPI-R4-bsp-6.1, the two BSP source code is for ubuntu and debian OS.

is there a reason why you go with sinovoip’s openwrt instead of the official one?

Isn’t BPI-SINOVOIP/BPI-R4-OPENWRT-V21.02 the official code base?

I just think it can produce the Openwrt images listed on BPI-R4 site above.

Good. I can build it and flash the NAND at least.
