Oh, and the docs show the baud rate to be 115200 like normal devices, but no - it's actually 1500000 baud. ---- Reopened serial port /dev/tty.usbserial-3120 ---- DDR 2d653b3476 typ 24/01/20-15:04:19,fwver: v1.21 In LP4/4x derate en, other dram:1x trefi ddrconfig:7 LPDDR4X, 324MHz BW=32 Col=10 Bk=8 CS0 Row=16 CS1 Row=16 CS=2 Die BW=16 Size=4096MB tdqss: cs0 dqs0: 48ps, dqs1: -48ps, dqs2: 24ps, dqs3: -120ps, tdqss: cs1 dqs0: 48ps, dqs1: -48ps, dqs2: 24ps, dqs3: -96ps, change to: 324MHz PHY dr:clk:36,ca:36,DQ:29,odt:0 vrefinner:24%, vrefout:41% dram drv:40,odt:0 clk skew:0x61 rx vref: 30.4% tx vref: 40.0% change to: 528MHz PHY drv:clk:36,ca:36,DQ:29,odt:0 vrefinner:24%, vrefout:41% dram drv:40,odt:0 clk skew:0x58 rx vref: 34.4% tx vref: 40.0% change to: 80MHz PHY drv:clk:36,ca:36,DQ:29,odt:60 vrefinner:16%, vrefout:41% dram drv:40,odt:0 clk skew:0x58 rx vref: 15.6% tx vref: 40.0% change to: 1560MHz(final freq) PHY drv:clk:36,ca:36,DQ:29,odt:60 vrefinner:16%, vrefout:22% dram drv:40,odt:80 vref_ca:00000071 clk skew:0x17 rx vref: 16.6% tx vref: 22.8% cs 0: the read training result: DQS0:0x35, DQS1:0x36, DQS2:0x35, DQS3:0x2f, min : 0xf 0x11 0x12 0x10 0x2 0x6 0x8 0x6 , 0xe 0xb 0x1 0x3 0xe 0xe 0xe 0xa , 0x10 0x10 0xb 0xa 0x2 0x4 0x6 0x6 , 0xa 0x7 0x4 0x1 0xe 0x11 0xc 0xf , mid :0x29 0x2b 0x2c 0x2a 0x1d 0x20 0x22 0x21 ,0x26 0x26 0x1 0x1e 0x28 0x28 0x28 0x25 , 0x2b 0x2b 0x24 023 0x1b 0x1d 0x1e 0x1f ,0x24 0x20 0x1e 0x1a 0x27 02a 0x25 0x28 , max :0x43 0x45 0x47 0x44 0x38 0x3a 0x3c 0x3d ,0x3e 0x41 0x38 0x39 0x42 0x43 0x43 0x41 , 0x47 0x4 0x3e 0x3d 0x34 0x36 0x36 0x39 ,0x3e 0x3a 0x38 0x34 0x40 0x43 0x3e 0x41 , range:0x34 0x34 0x35 0x34 0x36 0x34 0x34 0x37 ,0x30 0x36 0x37 0x36 0x34 0x35 0x35 0x37 , 0x37 0x37 0x33 0x33 0x32 0x32 0x30 0x33 ,0x34 0x33 0x34 0x33 0x32 0x32 0x32 0x32 , the write training result: DQS0:0x20, DQS1:0xe, DQS2:0x1b, DQS3:0x4, min :0x6f 0x73 0x74 0x71 0x63 0x68 x6a 0x6a 0x68 ,0x5c 0x59 0x52 0x52 0x5d 0x5d 0x5d 0x5b 0x58 , 0x6c 0x6d 0x68 0x68 0x5f 0x5e 0x5d 0x61 0x64 ,0x55 0x51 0x4e 0x4a 0x57 0x59 0x51 0x59 0x4e , mid :0x8b 0x8e 0x8f 0x8b 0x7c 0x82 0x84 0x82 0x81 ,0x76 0x75 0x6d 0x6c 0x78 0x76 0x76 0x75 0x71 , 0x88 0x89 0x81 0x81 0x79 0x76 0x77 0x7a 0x7d ,0x6f 0x6b 0x68 0x62 0x71 0x72 0x6c 0x73 0x68 , max :0xa7 0xa9 0xaa 0xa6 0x96 0x9c 0x9e 0x9a 0x9a ,0x910x91 0x89 0x86 0x93 0x90 0x90 0x8f 0x8b , 0xa5 0xa5 0x9b 0x9a 0x93 0x8f 0x92 0x93 0x97 ,0x89 0x86 0x83 0x7b 0x8c 0x8c 0x87 0x8d 0x83 , range:0x38 0x36 0x36 0x35 0x33 0x34 0x34 0x30 0x32 ,0x35 0x38 0x37 0x34 0x36 0x33 0x33 0x34 0x33 , 0x39 0x38 0x33 0x32 0x34 0x31 0x35 0x32 0x33 ,0x34 0x35 0x35 0x31 0x35 0x33 0x36 0x34 0x35 , cs 1: the read training result: DQS0:0x35, DQS1:0x36, DQS2:0x35, DQS3:0x2f, min : 0xf 0x11 0x12 0x10 0x2 0x6 0x8 0x6 , 0xe 0xb 0x1 0x3 0xe 0xe 0xe 0xa , 0x10 0x10 0b 0xa 0x2 0x4 0x6 0x6 , 0xa 0x7 0x4 0x1 0xe 0x11 0xc 0xf , mid :029 0x2b 0x2c 0x2a 0x1d 0x20 0x22 0x21 ,0x26 0x26 0x1c 0x1e 0x28 0x28 0x28 0x25 , 0x2b 0x2b 0x24 0x23 0x1b 0x1d 0x1e 0x1f ,0x24 0x20 0x1e 0x1a 0x27 0x2a 0x25 0x28 , max :0x43 0x45 0x47 0x44 0x38 0x3a 0x3c 0x3d ,0x3e 0x41 0x38 0x39 0x42 0x43 0x43 0x41 , 0x47 0x47 0x3e 0x3d 0x34 0x36 0x36 0x39 ,0x3e 0x3a 0x38 0x34 0x40 0x43 0x3e 0x41 , range:0x34 0x34 0x35 0x34 0x36 0x34 0x34 0x37 ,0x30 0x36 0x37 0x36 0x34 0x35 0x35 0x37 , 0x37 0x37 0x33 0x33 0x32 0x32 0x30 0x33 ,0x34 0x33 0x34 0x33 0x32 0x32 0x32 0x32 , the write training result: DQS0:0x20, DQS1:0xe, DQS2:0x1b, DQS3:0x4, min :0x6f 0x73 0x74 0x71 0x63 0x68 0x6a 0x6a 0x68 ,0x5c 0x59 0x52 0x52 0x5d 0x5d 0x5d 0x5b 0x58 , 0x6c 0x6d 0x68 0x68 0x5f 0x5e 0x5d 0x61 0x64 ,0x55 0x51 0x4e0x4a 0x57 0x59 0x51 0x59 0x4e , mid :0x8b 0x8e 0x8f 0x8b 0x7c 0x82 0x84 0x82 0x81 ,0x76 0x75 0x6d 0x6c 0x78 0x76 0x76 0x75 0x7 , 0x88 0x89 0x81 0x81 0x79 0x76 0x77 0x7a 0x7d ,0x6f 0x6b 0x68 0x62 0x71 0x72 0x6c 0x73 0x68 , max :0xa7 0xa9 0xaa 0xa6 0x96 0x9c 0x9e 0x9a 0x9a ,0x91 0x91 0x89 0x86 0x93 0x90 0x90 0x8f 0x8b , 0xa5 0xa5 0x9b 0x9a 0x93 0x8f 0x92 0x93 0x97 ,0x89 0x86 0x83 0x7b 0x8c 0x8c 0x87 0x8d 0x83 , range:0x38 0x36 0x36 0x35 0x33 0x34 0x34 0x30 0x32 ,0x35 0x38 0x37 0x34 0x36 0x33 0x33 0x34 0x33 , 0x39 0x38 0x33 0x32 0x34 0x31 0x35 0x32 0x33 ,0x34 0x35 0x35 0x31 0x35 0x33 0x36 0x34 0x35 , CA Training result: cs:0 min :0x55 0x50 0x47 0x42 0x48 0x3f 0x4a ,0x53 0x4a 0x49 0x3f 0x47 0x3e 0x4c , cs0 mid :0x92 0x91 0x84 0x82 0x85 x80 0x78 ,0x8f 0x8c 0x84 0x80 0x83 0x7f 0x7a , cs:0 max :0xcf 0xd2 0xc1 0xc3 0xc2 0xc1 0xa7 ,0xcb 0xce 0xc0 0xc2 0xbf 0xc1 0xa9 , cs:0 range:0x7 0x82 0x7a 0x81 0x7a 0x82 x5d ,0x78 0x84 0x77 0x83 0x78 0x3 0x5d , cs:1 min :0x52 0x54 0x47 0x47 0x47 0x44 0x4e ,0x54 0x4f 0x48 0x47 0x45 0x45 0x4b , cs:1 mid :0x92 0x91 0x86 0x84 0x85 0x81 0x7d ,0x94 0x8d 0x87 0x84 0x84 0x82 0x7b , cs:1 max :0xd3 0xce 0xc6 0xc2 0xc4 0xbe 0xad ,0xd5 0xcc 0xc6 0xc1 0xc3 0xc0 0xab , cs:1 range:0x81 0x7a 0x7f 0x7b 0x7d 0x7a 0x5f ,0x81 0x7d 0x7e 0x7a 0x7e 0x7b 0x60 , out U-Boot SPL board init U-Boot SPL 2017.09_armbian-2017.09-S93fe-P9666-Hbdb5-Vec91-Bbf55-R448a (Nov 06 2025 -

Ya, I know, but I haven't figured out how to work with these devices that have "built in" serial->USB adapters. The USBC becomes a serial port when connected to my computer, but that also powers it on, and it's not actually a port until the e25 has power. It's a catch-22. It needs power for the port to appear, and by the time the port appears and you've already missed part of the log. The e20c is much better, it has a separate power and debug port. 🙂 https://www.dropbox.com/scl/fi/u27poqubrg4rywz1xfjo5/IMG_3840.jpeg?rlkey=1mbl58bl8cy0b9i1s3xxjuh6y&dl=0

I connected UART today and did some debugging, and it looks like that this u-boot 2025.10 for Armbian 26.02 doesn't see NVMe drive, i.e. 'nvme scan' returns nothing. Is OPi5 NVMe support included in upstream mainline u-boot?

I've been trying to get the LCD working on my box. I've used Nicks image - Armbian-unofficial_25.05.0-trunk_X98h_bookworm_edge_6.12.11_xfce_desktop I've followed instructions for OpenVFD and tm16xx on these forums but both result in an Exec Format Error when I try to install the compiled module. From what I have read this is a version mismatch between the kernal and what the module was built with but when I compare uname -r with the vermagic of the module they match. I initially installed the linux headers from Nick's Github: linux-headers-edge-sunxi64_25.05.0-trunk_arm64_6.12.11. After I got the format error I tried installing headers from Armbian-config but get the same result. Make wouldn't work at all initially until I did a symlink between the relevant folders in usr/src and lib/modules. Maybe that stuffed something up?

@NicoD Hi! "FarmingSimulator 17" okay, I will try it.

@marcosdsdba I would compile this on the box. Install kernel headers. Post the errors you are getting. https://github.com/NickAlilovic/build/releases/download/20250306/linux-headers-edge-sunxi64_25.05.0-trunk_arm64__6.12.11-S62b2-Da873-P8a5c-C1abcH02eb-HK01ba-Vc222-B9bbb-R448a.deb

@Nick A Is it possible to create an image using the driver that Kevin posted? Because I tried to compile it and couldn't, several errors with .h file paths and C language function errors. Even importing the include linux/timer.h, etc., several errors occurred and I couldn't compile it on the SD card running Armbian. I don't know if I did something wrong or if I need to do it differently.

The Radxa bullseye image looks to boot fine, but Armbian forky does not boot at all.

@sicxnull

DTB extracted. Thanks! I should have some time this weekend to dig into getting wifi to work. @Nick A mentioned it might only work on kernel 4 so im unsure now but will see what i can do

@sicxnull I'm uploading it now and it will soon be available on my Google Drive at this link: https://drive.google.com/drive/folders/14Imqiz3u0qjLbLyDGkB0ratNn7k7-p6Z?usp=sharing

boot up armbian. check the /dev partition You will see mmcblk0 mmcblk2,etc The android image likely has many partitions. so you will see mmcblk2-9 etc, thats what we want Go ahead and dump the first 250mb (probably more than needed but just in case) into an image file and upload it, i can extract the dtb from that assuming mmcblk2 is what we want, you would run sudo dd if=/dev/mmcblk2 of=mmcblk2-first250mb.img bs=1M count=250 status=progress then upload that.

@brunorro What a read! That's cool stuff - hopefully those guys'n'gals visit the next station on their journey soon: from TH1520, via JH7110, then (hopefully) X1. At least that mailbox communication sounds similar with the SpacemiT SoC: power management via extra rCPU is also a thing here. Thank you for the link // Sven-Ola

@cal5582 Hav you plugged in your Oculink/Intel Arc combination to a standard PC's M.2 slot? Just to make sure, it's not the power supply for our power hungry graphical friends. If it is not the power supply (5V, 12V) then there is one difference from PC to OpiRV2: the OpiRV2's M.2 slot has only 2 PCIe lanes connected, while a standard PC has M.2/M-key connectors with 4 lanes normally. A graphics card may be used to a high number of lanes, so not only hungry for power but also for lanes. Also: there seems to exist Oculink adapters with an optical link between PC/board and card. In that case, I would expect an extra PCIe bridge to be shown with lspci.

I'm trying to enable UART6, UART7, and UART10 via overlays on a sige5 board. UART6 AND UART7 are working fine but I'm not seeing UART10 in the /dev directory. Could someone help me debug this?

@KhanhDTPHi. First off, great job with all these games. Would it be possible to test FarmingSimulator 17 please? I got the game working, but the image is offset a lot. Mouse also. I needed to set wine to win7 and use the x86 FarmingSimulator2017.exe in the x86 folder. I've got no clue how to fix this issue, maybe you have more tips and tricks. In windowed mode I can see everything, but mouse goes out of the window and stops working. Otherwise it looks playable if it was outputting correctly. Cheers, NicoD

@gabriel_altoe Try this: https://brandolamarck.substack.com/p/como-extrair-e-decompilar-a-device. I'll take some time to try and follow the tips. I'll post any updates here.

@sicxnull Yes, I can try to extract the DBT. How can I do that?

@Nick A Thank you very much, I'll try using it and get back to you if everything is okay.

Thank you, @sven-ola , your work is amazing About the GPU, I suppose that spacemit can do something like what this guy did to make work the BXM-4-64 on the TH1520 https://mwilczynski.dev/posts/riscv-gpu-zink/ Anyways, my hardware knowledge is way far away from this...

nvme drive is in the bottom slot, oculink adapter going to a powered external pci-e adapter in the top nvme slot. i was able to plug a non-gpu in it and get a device to detect. just both my intel arc gpus failed to detect. edit, new discovery, when the fpga device is active on the 2nd nvme slot i can no longer see my original nvme drive if booting off the sd card. very strange. almost like its a lane bifrucation issue. ignore that, misconfig on my end.
