I just found a very interesting talk by Sebastian Reichel who works with hardware enablement of the RK3588 at Collabora in this video between 06:52:09 to 07:27:07 which I can recommend for those interested in the Collabora project for Rockchip. Now also available here https://kernel-recipes.org/en/2023/schedule/getting-the-rk3588-soc-supported-upstream/

Thanks @Marco Schirrmeister for confirming my thought. I noticed that problem too! I should probably start building using this option. Not sure why I couldn't find it when running compile.sh though?

@teenytinycactus The current status of the collabora builds for rk3588 (6.5.0..) is it does boot nicely, but it only supports access through the debug serial port and Ethernet. It does not yet have HDMI support. You can use it for headless testing, but not yet for graphics.

PR now merged. Thanks.

Done.

Thanks @Werner

Hmm.. So I assume since my question relates to a board that is not maintained, the question is now moved to a different board? Formally correct. However, my fear is that a side-effect of this might be that I will not get any answers, since there seem to be very little traffic in this board? But hopefully I am wrong... @Werner can hopefully enlighten me? Maybe I should have sent a direct message to the maintainer instead?

I tried hackning the rock-5A.wip file to allow me to build the collabora version, and it worked quite nicely! The board boots into linux and the ethernet port and usb seem to work! so should i try to send up a pull request to the armbian GitHub to include this change, an if so How should i do this? otherwise someone else with experience is wecome to do it too! / Kenneth

Am I right in assuming that bootsize=512 creates a boot partition of size 512 mb? Skickat från min LE2123 via Tapatalk

Yes, true, but on the other hand, shouldn't it be possible to just copy the older dts files and try with those? I have not worked with device tree before, but the device-tree files does seem to be kind-of kernel-version independent...? What would happen if we tried to copy the ones from 4.19 and reuse those together with one of the newer kernels?

Yes I noticed that there seem to patch files for one kernel too but I think that kernel (4.19) might not be used. Someone else can correct me... As far as I've seen the legacy kernel is currently 5.10.

Yes, I agree, I'll look into it further when I have time.

I noticed today that there was no build created yet for Radxa Rock 3C. I found the Rock 3A config file at build/config/boards/rock-3a.conf : # Rockchip RK3568 quad core 1-8GB SoC GBe eMMC USB3 BOARD_NAME="Rock 3A" BOARDFAMILY="rk35xx" BOOTCONFIG="rock-3a-rk3568_defconfig" KERNEL_TARGET="legacy,current,edge" FULL_DESKTOP="yes" BOOT_LOGO="desktop" BOOT_FDT_FILE="rockchip/rk3568-rock-3a.dtb" BOOT_SCENARIO="spl-blobs" WIREGUARD="no" BOOT_SUPPORT_SPI="yes" BOOT_SPI_RKSPI_LOADER="yes" IMAGE_PARTITION_TABLE="gpt" BOOTFS_TYPE="fat" And copied it to build/boards/rock-3c.conf . Then modified it to # Rockchip RK3566 quad core 1-8GB SoC GBe eMMC USB3 BOARD_NAME="Rock 3C" BOARDFAMILY="rk35xx" BOOTCONFIG="rock-3c-rk3566_defconfig" KERNEL_TARGET="legacy,current,edge" FULL_DESKTOP="yes" BOOT_LOGO="desktop" BOOT_FDT_FILE="rockchip/rk3566-rock-3c.dtb" BOOT_SCENARIO="spl-blobs" BOOT_SUPPORT_SPI="yes" BOOT_SPI_RKSPI_LOADER="yes" IMAGE_PARTITION_TABLE="gpt" BOOTFS_TYPE="fat" And was pleasantly surprised when it was able to build an image! 🙂 However, the booting was not so successful I get this on the UART (1500000 bps 8N1): DDR Version V1.10 20210810 ln ddrconfig:0 LP4 MR14:0x4d LPDDR4, 324MHz BW=32 Col=10 Bk=8 CS0 Row=17 CS=1 Die BW=16 Size=4096MB tdqss: cs0 dqs0: 361ps, dqs1: 289ps, dqs2: 313ps, dqs3: 217ps, change to: 324MHz PHY drv:clk:38,ca:38,DQ:30,odt:0 vrefinner:41%, vrefout:41% dram drv:40,odt:0 clk skew:0x58 change to: 528MHz PHY drv:clk:38,ca:38,DQ:30,odt:60 vrefinner:16%, vrefout:41% dram drv:40,odt:0 clk skew:0x78 change to: 780MHz PHY drv:clk:38,ca:38,DQ:30,odt:60 vrefinner:16%, vrefout:41% dram drv:40,odt:0 clk skew:0x5c change to: 1056MHz(final freq) PHY drv:clk:38,ca:38,DQ:30,odt:60 vrefinner:16%, vrefout:29% dram drv:40,odt:80 vref_ca:00000068 clk skew:0x3f cs 0: the read training result: DQS0:0x3b, DQS1:0x3d, DQS2:0x3d, DQS3:0x38, min : 0x9 0xa 0xc 0x9 0x1 0x2 0x5 0x2 , 0x8 0x9 0x5 0x1 0xb 0xd 0xf 0x9 , 0xd 0xb 0xc 0x8 0x4 0x1 0x4 0x6 , 0xb 0x6 0x6 0x1 0xf 0xe 0xd 0xe , mid :0x28 0x29 0x2b 0x28 0x1f 0x21 0x23 0x21 ,0x26 0x27 0x22 0x1f 0x29 0x2b 0x2c 0x27 , 0x2b 0x2a 0x29 0x27 0x22 0x1f 0x21 0x23 ,0x28 0x23 0x23 0x1f 0x2b 0x2b 0x29 0x2b , max :0x48 0x49 0x4b 0x47 0x3e 0x40 0x42 0x41 ,0x45 0x45 0x40 0x3e 0x47 0x49 0x4a 0x46 , 0x4a 0x49 0x46 0x46 0x41 0x3e 0x3f 0x41 ,0x45 0x41 0x40 0x3d 0x48 0x48 0x46 0x49 , range:0x3f 0x3f 0x3f 0x3e 0x3d 0x3e 0x3d 0x3f ,0x3d 0x3c 0x3b 0x3d 0x3c 0x3c 0x3b 0x3d , 0x3d 0x3e 0x3a 0x3e 0x3d 0x3d 0x3b 0x3b ,0x3a 0x3b 0x3a 0x3c 0x39 0x3a 0x39 0x3b , the write training result: DQS0:0x6f, DQS1:0x66, DQS2:0x69, DQS3:0x5c, min :0x95 0x97 0x99 0x97 0x8f 0x92 0x94 0x94 0x94 ,0x88 0x88 0x86 0x83 0x8d 0x8e 0x8e 0x8d 0x89 , 0x92 0x91 0x8e 0x8e 0x89 0x87 0x8a 0x8e 0x8d ,0x86 0x85 0x83 0x7f 0x8a 0x8a 0x88 0x8c 0x85 , mid :0xb2 0xb4 0xb6 0xb3 0xab 0xad 0xaf 0xae 0xae ,0xa6 0xa5 0xa1 0x9e 0xaa 0xaa 0xa9 0xa9 0xa6 , 0xaf 0xae 0xab 0xaa 0xa5 0xa1 0xa3 0xa9 0xa9 ,0xa4 0xa1 0xa0 0x9b 0xa7 0xa7 0xa5 0xa8 0xa2 , max :0xd0 0xd1 0xd3 0xcf 0xc7 0xc9 0xcb 0xc9 0xc9 ,0xc4 0xc3 0xbd 0xba 0xc7 0xc7 0xc5 0xc5 0xc3 , 0xcd 0xcb 0xc8 0xc6 0xc2 0xbc 0xbc 0xc4 0xc6 ,0xc2 0xbd 0xbd 0xb8 0xc5 0xc5 0xc2 0xc5 0xc0 , range:0x3b 0x3a 0x3a 0x38 0x38 0x37 0x37 0x35 0x35 ,0x3c 0x3b 0x37 0x37 0x3a 0x39 0x37 0x38 0x3a , 0x3b 0x3a 0x3a 0x38 0x39 0x35 0x32 0x36 0x39 ,0x3c 0x38 0x3a 0x39 0x3b 0x3b 0x3a 0x39 0x3b , CA Training result: cs:0 min :0x3d 0x35 0x37 0x2d 0x37 0x2c 0x38 ,0x3f 0x34 0x37 0x2c 0x37 0x2a 0x3c , cs:0 mid :0x78 0x79 0x71 0x70 0x71 0x6f 0x63 ,0x79 0x77 0x71 0x6f 0x70 0x6e 0x67 , cs:0 max :0xb3 0xbd 0xab 0xb3 0xab 0xb3 0x8e ,0xb4 0xbb 0xac 0xb2 0xaa 0xb2 0x92 , cs:0 range:0x76 0x88 0x74 0x86 0x74 0x87 0x56 ,0x75 0x87 0x75 0x86 0x73 0x88 0x56 , out U-Boot SPL board init U-Boot SPL 2017.09-armbian (Jun 10 2023 - 09:59:15) unknown raw ID phN unrecognized JEDEC id bytes: 00, 00, 00 Trying to boot from MMC2 ## Verified-boot: 0 ## Checking atf-1 0x00040000 ... sha256(5938a9cdfc...) + OK ## Checking uboot 0x00a00000 ... sha256(d801f0f359...) + OK ## Checking fdt 0x00b2e6f8 ... sha256(3ccee0dc53...) + OK ## Checking atf-2 0x00068000 ... sha256(0965dc8022...) + OK ## Checking atf-3 0xfdcd0000 ... sha256(be991af043...) + OK ## Checking atf-4 0xfdcc9000 ... sha256(695349eb36...) + OK ## Checking atf-5 0x00066000 ... sha256(315a4195a9...) + OK Jumping to U-Boot(0x00a00000) via ARM Trusted Firmware(0x00040000) Total: 237.208 ms INFO: Preloader serial: 2 NOTICE: BL31: v2.3():v2.3-167-g81e0b993a-dirty:xsf NOTICE: BL31: Built : 11:20:08, Sep 6 2021 INFO: GICv3 without legacy support detected.

Any hints on what direction to dig for getting it closer to booting would be appreciated? / Kenneth

Could anyone point me in a good direction if I wanted to start learning how to get the Rock 5B HDMI driver running for the 6.x kernel? I'm looking for where it's located in the Linux file structure, but also documents and possible support files / repositories from Rockchip. /Kenneth

Now it's booting (although it took some time, at least the first boot)! It says efi: EFI: v2.70 by EDK II in dmesg, so that seems promising.
