wahaha 4 Posted January 3 I am referring to https://github.com/TinkerBoard-Linux where the newer kernel 5.10 is found. I want to build the uboot.img and trust.img and flash them onto an empty SD card. meaning, there's no partition on it yet. How should i do it? Note: I am familiar with how to build a kernel. but not sure how to flash it onto empty sd card also. I found the partition list here http://opensource.rock-chips.com/wiki_Partitions --> should i just sudo dd and write them into the respective locations and thats it?

wahaha 4 Posted January 3 FYI - I am trying to install Fedora server on the tinkerboard 2s. not debian. Share this post Link to post Share on other sites
tooz 52 Posted January 4 hello @wahaha, to generate uboot.img for sd cards: 1. please compile the .img with command (aka 'the normal way' to compile .imgs) ./build.sh 2. use sdboot.sh to overwrite the device/rockchip/common/scripts/sdboot.sh in the sources sdboot.sh can be downloaded here: https://www.asuswebstorage.com/navigate/a/#/s/8D32B97F2E6D428A9344DB456B2CC5464 3. generate sd_uboot.img with command sudo ./device/rockchip/common/scripts/sdboot.sh -t uboot the sd_uboot.img will be located in rockdev directory 4. flash sd_uboot.img to sd card -- you can either use tools like balenaetcher or the sudo dd command Share this post Link to post Share on other sites
wahaha 4 Posted June 2 (edited) Hi @tooz, Sorry I missed your reply..! I was revisiting this again, but i don't see where ./build.sh is. I cloned https://github.com/TinkerBoard-Linux/rockchip-linux-u-boot which is for kernel 5.10 uboot it seems. but can't seem to build the uboot. 2nd qns: the guide you posted above is purely to build the uboot right? I still have to build the kernel separately, and the OS image? Can you share how the OS image can also be flashed onto the sdcard please? Thank you, Edited June 2 by wahaha Share this post Link to post Share on other sites
tooz 52 Posted June 3 hello @wahaha, you still need to download all the sources and build a complete os image in order to make the sd card work; unfortunately only building u-boot image is not enough. the easiest way is to compile the complete .img and then change the rootfs to compile u-boot: git clone https://github.com/TinkerBoard-Linux/rockchip-linux-rkbin.git mv rockchip-linux-rkbin rkbin git clone https://github.com/TinkerBoard-Linux/rockchip-linux-prebuilts-gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu.git git clone https://github.com/TinkerBoard-Linux/rockchip-linux-u-boot.git cd rockchip-linux-u-boot ./make.sh tinker_board_2 CROSS_COMPILE=/path/to/rockchip-linux-prebuilts-gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- *please change the path of CROSS_COMPILE=/ to where rockchip-linux-prebuilts-gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- is located Share this post Link to post Share on other sites

wahaha 4 Posted June 25 (edited) Hi @tooz, I've successfully ran ./make.sh tinker_board_2 CROSS_COMPILE=/path/to/rockchip-linux-prebuilts-gcc-arm-10.3-2021.07-x86_64-aarch64-none-linux-gnu/bin/aarch64-none-linux-gnu- I noticed that in the make.sh file, it says -> board built okay, there are uboot/trust/loader images in current directory. From this below image, I understand that uboot and trust image can be written into the sd card via the sudo dd command. Curious, what do I need the loader that was created also? I also understand that boot is the kernel. But what about misc, recovery, backup? How do they get generated? Edited June 25 by wahaha Share this post Link to post Share on other sites
