NPU is functional on https://github.com/ut-slayer/orangepi-4a-mainline https://github.com/defencedog/orangepi4A/tree/main/NPU_modules_opi4a_6.18.44 https://github.com/defencedog/orangepi4A/tree/main/NPU_proj_opi4a_6.18.44 Many inference functions are missing from mainline NPU support (many works though which were exploited in x3 NPU projects) However I do use NPU for pdf OCR which I cannot do here https://github.com/defencedog/orangepi3b_v2.1/tree/main/apps/NPU_OCR

v0.3 is out wuth VPU_GPU support https://github.com/ut-slayer/orangepi-4a-mainline/releases/tag/v0.3 Testers needs with to test NVME boot

a very exciting development on mainline with VPU_GPU acceleration enabled https://github.com/ut-slayer/orangepi-4a-mainline/issues/2#issuecomment-5030458197

Anyone has a working image with GPU / VPU support? In the official Jammy I am using VPU is supported via gstreamer / CEDRA https://github.com/defencedog/orangepi4A/tree/main/GPU_VPU

Any Ubuntu Noble release?

I further expanded kernel because VPN clients like twingate needed a module `tun` more on this here https://github.com/defencedog/orangepi4A/tree/main/kernels#update-2

Regarding the VPU under jammy I have compiled a guide here https://github.com/defencedog/orangepi4A/tree/main/GPU_VPU Gstreamer players like clapper do use HW acceleration for H264 & H265 (however 10bit HEVC) are not working ad per my tests Version 1.0 of `libcedarc` is used. In v2.0 HEVC 10bit support is added. If anyone can provide git links & some help to compile I am ready to spend time on it In whole internet I only got x1 git for this https://gitlab.com/tina5.0_aiot/media/cedarc-release/libcedarc_v2.0

I think this OS for T527 Allwinner should work on 4A. Official 4A releases are stuck at jammy while this has Noble https://github.com/AvaotaSBC/AvaotaOS/releases If you observe the contents inside `linux-dtb-sun55i-t527-bsp_0.3.0.4_arm64.deb` you will realise it's doesn't have 4A `dtb` So after burning image copy `dtb` File from jammy. Kernel is same so I belive it should work

I am a new user to Allwinner T527 SOC in OrangePi 4A.... The SBC is great for general purposes but VPU really sucks. On the other hand my RK3566 SOC in OPi3b & Radxa Zero 3E shines when using JellyFin or Chrome

OrangePi 4A Bluetooth Mouse Keyboard connectivity issue Solved The solution to the problem when mouse pairs / connects with BT but doesnt work Prebuilt kernel files are available https://github.com/defencedog/orangepi4A/blob/main/Bluetooth%20Mouse%20Not%20Working%20Solved.md

I have having the same issue as discussed here & it also provided solution for it https://github.com/IceWhaleTech/CasaOS/issues/1136 I have added cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1 to armbianEnv.txt The dmesg logs indicate that these arguments are failing [ 15.630904] Kernel command line: root=UUID=eb6a27ef-3932-431f-92fd-e61fea75356c rootwait rootfstype=ext4 splash=verbose console=ttyS2,1500000 console=tty1 consoleblank=0 loglevel=1 ubootpart=f3aeb909-d11b-ec42-a52c-4507e474335c usb-storage.quirks=0x2537:0x1066:u,0x2537:0x1068:u,0x1058:0x25a2:u cma=256M cgroup_enable=cpuset cgroup_enable=memory cgroup_memory=1 cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory [ 15.631910] Unknown kernel command line parameters "splash=verbose ubootpart=f3aeb909-d11b-ec42-a52c-4507e474335c cgroup_enable=memory cgroup_memory=1", will be passed to user space. . . .

@Fajar Muttaqin Can you share your compiled kernel & headers `.debs` In default kernel support for filesystems `cifs` & `nfs` were not included. I compiled with these support as well https://github.com/defencedog/orangepi4A/tree/main/kernels

@Angel Luis Pérez Can you please upload your debian image. Plus kindly explain which hardware part is not working?
