UPDATE for Multitool Finally I managed to let the Opensource OP-TEE work with the rockchip miniloader! This means that the Multitool should now work on any board, without freezes and booting issues! The new version can be downloaded from the first page of this thread. Please report if it works for you, thanks!

I updated to Armbian 26.2.1 on OPi5, and it can't boot from MTD (rootfs at NVMe), and I have to use SD card to boot to NVMe as workaround. After looking into this issue, I found rkspi_loader.img is no longer available for current (6.18.8 kernel) u-boot pkg and armbian-config flashes u-boot-rockchip-spi.bin ( or similar sata version) to /dev/mtdblock0 and I think this is wrong image for MTD bootloader. If I use older vendor image, which u-boot pkg has rkspi_loader.img, system can boot to NVMe rootfs and I notice that /dev/mtdblock0 has several gpt partitions including u-boot one, and flashing u-boot-rockchip-spi.bin erases partitions in SPI flash. I noticed that several related changes were introduced since 25.11, such as https://github.com/armbian/build/commit/e5b845f9432abb0408287599bba5889a86e6d068 , but I couldn't do quick fix to bring back working rkspi_loader.img because I am not familiar with whole armbian build. One thing to note that if board was flashed with old rkspi_loader.img and not updated with 26.2 MTD image, it still boots to NVMe rootfs, but I have other issues such as video playback not working with 6.18 kernel likely due to mismatch u-boot and kernel version leading to wrong HW initialization. BTW, I checked 26.2 u-boot pkg for Rock 5B (similar rk3588 board), and rkspi_loader.img is still included.

@jock Hi, I have updated the build source for the leds overlay files (leds 6 and 7) for both the the rockchip64 H50 tvbox and the T9 tvbox, for kernels 6.12 (old non scrolling driver) and 6.18 (new scrolling driver) the version for 6.18 is also fine for 6.19. Have a look at my fork in https://github.com/gpaesano/build. Some modifications are just refinements other are functional. I have built all the images and variants on a ubuntu linux and are running well. I am not familiar with pull requests and do not want to be impolite, so If you think there is some added value please support it. All the best @GmP

If anyone is still interested, I have a Helios 64 that I assembled, looked at, but never got around to using for more than a couple hours. Works fine, does not yet have the 2.5GB fix but I have the instructions for same. No idea what to ask for it but it certainly isn't doing me any good sitting on my shelf. Have the manual, SATA drive bay adapters for 2.5" drives and the like. Make me an offer and pay shipping from Oregon. Let's talk!

https://github.com/armbian/community/releases/download/26.2.0-trunk.385/Armbian_community_26.2.0-trunk.385_Rk3318-box_trixie_current_6.18.8_minimal.img.xz this is the latest console build compatible with T9. You will need to configure a little bit the environment after booting to enable all the features via ssh and wired lan. If the device is still on android the best is to follow the tutorial from @jock in
