I forked the repo and the build worked. The previous build, there was an issue with the .patch file I wrote. I've also added Heltec HC01P support. |

@andrewsuggs465 do you also have a Seeed Studio board and Pi hat? An unknown here is if your changes to the linux patches would break the existing support for the Seeed Studio board and the Pi4 |

- Add package/utils/persistent-vars-storage-bcm2712 for RPi5 EEPROM storage (mirrors bcm2711 variant with @TARGET_bcm27xx_bcm2712 guard) - Fix boards/ekh-bcm2712/target_diffconfig: use bcm2712 package instead of bcm2711 which has a hard @TARGET_bcm27xx_bcm2711 dependency - Add .github/workflows/build-pr-bcm2712.yml to CI-validate the new board on every PR touching boards/ekh-bcm2712/ or target/linux/bcm27xx/
The openwrt/actions-shared-workflows formal.yml requires pull-requests: write to post check summaries as PR comments. Without this the caller workflow fails at startup when triggered from a fork PR.
- Add build-ekh-bcm2712 job using cpu_arch aarch64_cortex-a76 - Add ekh-bcm2712 to needs arrays in publish-packages and release jobs so RPi5 firmware is included in official releases
Superseded by build-release.yml which handles the same v* tag trigger but also builds all firmware, publishes packages, and creates a proper release with artifacts. Having both caused duplicate competing draft releases on every tag push.
BCM2712 does not use the VPU start.elf/fixup.dat boot model; the EEPROM bootloader loads the kernel directly. Copying start4*.elf and fixup4*.dat into the RPi5 boot partition is unnecessary and diverges from the stock Device/rpi-5 recipe (boot-common | sdcard-img). Remove Build/boot-2712 and use boot-common | boot-rpi5-morse instead.
The firmware overlay loader fails the entire overlay if any fragment target label is unresolvable. Mixing RP1 fragments (&rp1_mmc0, &rp1_spi0, &rp1_gpio) into the shared mm_wlan/mm610x-spi/mm810x-spi overlays would therefore break overlay application on Pi 3/4 and Seeed boards, which lack those labels. - Restore 991-0001 and 991-0003 to their upstream (Pi 1-4 only) form - Add 991-0008 creating mm_wlan-pi5, mm610x-spi-pi5, mm810x-spi-pi5 overlays with the RP1 fragments - Register the -pi5 dtbos in the overlays Makefile patch - Point the rpi5 distroconfig files at the -pi5 overlay names and add missing trailing newlines (boot-rpi5-morse concatenates these files; a missing final newline merged two config lines into one)
