I spent my weekend (and some evenings) updating the OpenWrt build for the BPi-R2.

What I did:

  • bumped Linux to 5.10.51
  • updated U-Boot to 2021.04, many new features enabled
  • colorful bootmenu and recovery vs. production dual-boot, just like on the R64 (but no PSTORE yet, not sure if that’s even possible with the old preloader)
  • no more external scripts and helpers involved in build, all the magic happens in target/linux/mediatek/image/mt7623.mk now.
  • no more bootfs FAT partition – now that we have support for parsing uImage.FIT in Linux, there is no need to imitate this anti-pattern originating from the IBM PC and MSDOS…
  • just like on the R64, bootdevice is auto-detected when accessing U-Boot environment from inside OpenWrt (fw_printenv now installed by default) and also sysupgrade works on both, eMMC and SD card, depending on what was used for booting.

What is not working yet:

  • HDMI and multimedia features (@frank-w is working on that with upstream afaik)
  • 2nd CPU port connected to MT7530 switch (making use of dsa-tag-protocol could help)
  • on-board IEEE802.11bgn 1T1R WiFi (no driver)
  • Bluetooth (?)
  • some LEDs are not mapped correctly (volunteers?)
  • AHCI driver triggers some MSI related warnings, SATA seems to work nice anyway

It’s going to take a while for the buildbots to generate new snapshot images (ie. we have to wait for build #189 to run through on https://buildbot.openwrt.org/master/images/#/builders/50 ), once it’s ready you can download from https://downloads.openwrt.org/snapshots/targets/mediatek/mt7623/openwrt-mediatek-mt7623-bananapi_bpi-r2-sdcard.img.gz which still gives you Error 404 now, but that’s going to change within the next hours.

In the meantime you can already try when building from source yourself.
