Mortis1369 0 Posted February 21, 2023 I have no idea how active this community is, but I chose the Tinker Board 2s as a platform for one of my projects. The github repo link is dead. I managed to find a fork that was functional, but it isn't complete. Is there some other source where I can draw all of the files necessary (minus the source code for AOSP as I already have it) in order to begin developing my operating system for this board? Or should I just resort to brute force and make a blob? Share this post Link to post Share on other sites

MarciS 0 Posted January 4 Hello all, is there a reference page with build instruction? I just found the reference page with the download instruction here manifest . Nevertheless, I couldn't find any guide with a procedure that describes it. Share this post Link to post Share on other sites
tooz 47 Posted January 5 hello @MarciS, the build instruction for tinker board 2s: https://github.com/TinkerBoard/TinkerBoard/wiki/Tinker-Board-2-&-2S#21-build-image there are quite a lot of versions so be sure to use the right one when you do repo init -u (manifest) -b -m 1 Share this post Link to post Share on other sites
MarciS 0 Posted January 14 Hello, thank you for the feedback. The link was very useful, nevertheless I had some issues when building u-boot and the kernel (for the moment I tests these). For u-boot I get Error: arch/arm/dts/.rk3036-sdk.dtb.pre.tmp:77.1-10 syntax error FATAL ERROR: Unable to parse input tree make[2]: *** [scripts/Makefile.lib:319: arch/arm/dts/rk3036-sdk.dtb] Error 1 make[2]: *** Waiting for unfinished jobs....

This allowed me to discard all other board and build only for rk3399. @tooz Do you know if this may cause future issue or it can be accepted? About the kernel instead: I was never able to build the kernel with clang.

It is like they are not compiled at all so they cannot be added during the build process. I've also tried to use only one job to build but nothing changed. The only thing I've found to have the kernel compilation working was by changing the file kernel/drivers/media/i2c/cam_sensor/Makefile with the content: #cam_sensor-objs := \ # cam_sensor_core.o \ # cam_imx219.o \ # cam_ov5647.o cam_sensor_objs := #obj-$(CONFIG_VIDEO_CAM_SENSOR) += cam_sensor.o obj-$(CONFIG_VIDEO_CAN_SENSOR) += Nevertheless this means that no camera sensor are added at all. @tooz do you know if this is due to the missing step with clang? Do you know if there is a way to fix it? Thank you! Share this post Link to post Share on other sites
tooz 47 Posted January 16 hello @MarciS, what are the commands you used for downloading source codes/ compiling? are you using the codebase from: https://github.com/TinkerBoard2-Android/kernel/tree/android11-rk3399/drivers/media/i2c/cam_sensor ? cam_imx219.c, cam_ov5647.c, cam_sensor_code.c are only available in android 11 Share this post Link to post Share on other sites
MarciS 0 Posted February 12 Hell @tooz, to download I used $ repo init -u https://github.com/TinkerBoard2-Android/manifest.git -b android11-rk3399 -m tinker_board_2-android11-2.0.1.xml $ repo sync and to build I used the these instruction from 2.1 Build image source build/envsetup.sh lunch WW_Tinker_Board_2-userdebug ./build.sh -UKAu Note that I removed the option C build kernel with Clang because it was failing and I wasn't able to fix it.

tooz 47 Posted February 16 hello @MarciS, ./build.sh -UCKAu not working is not an expected result, what is your build environment? Share this post Link to post Share on other sites
