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/

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.
