  1. Update: a working Armbian image (both SD card and eMMC) has been made available from c0rnelius / pyavitzhttps://github.com/pyavitz/binary/releases/download/images/rk3399-nanopi-r4se-debian-bullseye-5.19.11-arm64-2022-09-27.img.xz

     

    Boot using an SD card (either the image above or the Armbian R4S image with my dtb file above) and run the following to image the eMMC:

     

    wget https://github.com/pyavitz/binary/releases/download/images/rk3399-nanopi-r4se-debian-bullseye-5.19.11-arm64-2022-09-27.img.xz

    xz -dc rk3399-nanopi-r4se-debian-bullseye-5.19.11-arm64-2022-09-27.img.xz | dd of=/dev/mmcblk2 status=progress

     

     

    Note: if booting using pyavitz image from an SD card, you'll need to use a toothpick to press in the MASK button on the R4SE for 3 seconds during power on to use the SD card bootloader.

  2. Armbianmonitor:

    I loaded both the Raxda Debian OS and the Armbian OS on the Rock Pi 4A+ (4GB RAM / 32GB eMMC) integrated eMMC chip and both boot fine. I then ran the Phoronix pts/scikit-learn benchmark and got a big discrepancy in performance: https://openbenchmarking.org/result/2112285-NE-2112281NE08

     

    The Raxda Debian OS (noted as rockpi4a+raxdadebian in the benchmark) performs basically the same as the Rock Pi 4A version (noted as rockpi4-rk3399 running Armbian), as expected. The Armbian OS (tested multiple times as rockpi4a-emmc, rockpi4a+, rockpi4a+governor, and rockpi4a+armbian) all perform terribly.

     

    Thoughts?
