    could you guys release 1 for kernel 5.15.x please? or share how we can compile our own kernels?

    Hi guys. Let me share Android 11 for Tinkerboard / Tinkerboard S 1-st revision (not R2.0) which Asus marked as outdated/legacy. You can find download link below: Download Android 11 ROM Tinkerboard (not R2.0) Bug reporting are welcome. Release is based on official Asus firmware for Tinkerboard S R2.0.

    Hi everybody, Recently, I have been trying to run some bare metal code on my Tinker Board 2. I managed to compile ARM Trusted Firmware - A successfully with these commands: % git clone https://github.com/ARM-software/arm-trusted-firmware.git tf-a % cd tf-a % export CROSS_COMPILE=~/Developer/Toolchains/aarch64-none-elf/bin/aarch64-none-elf- % make PLAT=rk3399 After that, I tried to build U-Boot with these commands (the CROSS_COMPILE variable is set from previous commands): % git clone https://github.com/TinkerBoard2/u-boot.git uboot % cd uboot % export BL31=../tf-a/build/rk3399/release/bl31/bl31.elf % export KBUILD_OUTPUT=build % make tinker2_defconfig % make This, unfortunately failed with this error: DTC arch/arm/dts/rk3036-sdk.dtb Error: arch/arm/dts/.rk3036-sdk.dtb.pre.tmp:77.1-10 syntax error FATAL ERROR: Unable to parse input tree I tried to fix the problem, and I thought removing 'rk3036-sdk.dtb' from 'arch/arm/dts/Makefile' could work since it seemed to be the device tree of another board that I was building for, which happened to be ill formed. That made the problem disappear, but the same thing happened for 'rk3368-lion.dtb', 'rk3368-sheep.dtb' and a couple of other device trees. I removed them all (7 in total) and the build finally succeeded. I then created a GPT disk image, with a single FAT32 partition with my code compiled, in it. The partition started at sector 18405, so there should have been plenty space for U-Boot. I verified with gdisk that my disk image is not corrupt, so that is clearly not the problem. I tried writing U-Boot into the SD card with the instructions in https://github.com/u-boot/u-boot/blob/master/doc/README.rockchip and https://github.com/u-boot/u-boot/blob/master/doc/board/rockchip/rockchip.rst. Packaging with rockchip miniloader did kind of work, but it printed some unusual characters (Chinese or Japanese?) and a lot of diamonds with single question mark in them at the beginning, and I had to set the baud rate to 120000 to view the output properly. Using U-Boot SPL and U-Boot TPL + SPL only printed one diamond with a question mark in it. I also tried the method provided as an answer to this post, but that did not work, probably because it was for eMMC. I used this command to see if it worked: minicom -D /dev/cu.usbserial-1440 -b 115200 -o I connected my serial to USB cable as instructed in this post I am sure my board is not broken as I was able to run the official Debian image without U-Boot printing any weird characters or problems with baud rate. I wonder, if any Tinker Board engineers could share how U-Boot is built when preparing the official image. Any help is appreciated.

    I was able to update Asus's debian to latest version by adding deb http://ftp.us.debian.org/debian testing main contrib non-free to /etc/apt/sources.list.d and then run "sudo apt update" "sudo apt upgrade" but... Disappointed with support level, Asus almost no activity, several questions not answered, software outdated etc

    hello @Tolga, please refer to the setting below. It’s not necessary to use uart1, uart2 or uart4 can be used, too. Using uart3 however is not suggested, since it’s used for uart log output https://github.com/TinkerBoard/TinkerBoard/wiki/User-Guide#gpio-config-table-for-tinker-board-and-tinker-board-s First, modify the /boot/config.txt file as follows, and then reboot to enable I2C1 and I2C4. ##### Hardware Interface Config ####### Note: fiq_debugger and uart3 use the same pin.

    Kernel Build Questions in Tinker Edge T I installed Mendel 5 Eagle V3.0.2 on Tinker Edge T. I want to change Boot Logo of Tinker Edge T, and I want to communicate with UART device in Mendel Linux. To change the Boot Logo, Kernel must be compiled. Where can I download the kernel source for Mendel 5 Eagle V3.0.2? And, what do I need to do to communicate with the UART device in mendel linux? Guid documentation says /dev/ttymxc0 and /dev/ttymxc2 should exist, but I see /dev/ttymxc0 and /dev/ttymxc1. If /dev/ttymxc1 is checked, it is said to be incorrect. I need help with the above two. regards.

    Hi @Excel Tinker board 2 supports 3x USB 3.2 Gen 1 TYPE-A ports and 1x USB3.2 Gen 1 TYPE-C OTG port. The TYPE-A and TYPE-C ports are each in a separate USB 3.2 Gen 1 group. Since the three TYPE-A ports of Tinker Board 2 are implemented by USB HUB. When each TYPE-A port is used individually, each port can support up to 5Gbps; however, when all 3 TYPE-A ports are used simultaneously, they will share 5Gbps of bandwidth. If you have a requirement for two 5Gbps USB ports, it is recommended that you use TYPE-A and TYPE-C to implement your requirement, respectively. Thanks.

    Hi @CyberT: The config table's naming of asus gpio input and output node are for Tinker Board S. And, the packages are development by third party member(https://github.com/tinycore-hisanori/node-red-contrib-tinkeros-gpio). But, i think it is compatible with Tinker Board 2 about gpio pin number. You can replace the attachment file to /home/linaro/.node-red/node-moduels/red-contrib-tinkeros-gpio/nrgpio.sh file and asus output node would work by add sudo permission for Tinker Board 2. Please help to try and verify it. Thank a lot! nrgpio.sh

    I was a bit busy lately, but after some investigation I managed to find the reason some device trees failed to compile. I realized that "make" invokes the part that causes the error like this in a linux VM: (cat ../arch/arm/dts/rk3036-sdk.dts; echo '#include "rk3036-sdk-u-boot.dtsi"') > arch/arm/dts/.rk3036-sdk.dtb.pre.tmp; while in macOS it is invoked like this: (cat ../arch/arm/dts/rk3036-sdk.dts; echo '\#include "rk3036-sdk-u-boot.dtsi"') > arch/arm/dts/.rk3036-sdk.dtb.pre.tmp; It seems to be caused by the hash character having a special meaning in shell. I managed to fix, and here is the patch: diff --git a/scripts/Makefile.lib b/scripts/Makefile.lib index 12d1123a07..9e419a0890 100644 --- a/scripts/Makefile.lib +++ b/scripts/Makefile.lib @@ -6,6 +6,8 @@ asflags-y += $(EXTRA_AFLAGS) ccflags-y += $(EXTRA_CFLAGS) cppflags-y += $(EXTRA_CPPFLAGS) ldflags-y += $(EXTRA_LDFLAGS) + +hash = \# # # flags that take effect in sub directories @@ -308,7 +310,7 @@ quiet_cmd_dtc = DTC $@ # Modified for U-Boot # Bring in any U-Boot-specific include at the end of the file cmd_dtc = mkdir -p $(dir ${dtc-tmp}) ; \ - (cat $<; $(if $(u_boot_dtsi),echo '\#include "$(u_boot_dtsi)"')) > $(pre-tmp); \ + (cat $<; $(if $(u_boot_dtsi),echo '$(hash)include "$(u_boot_dtsi)"')) > $(pre-tmp); \ $(CPP) $(dtc_cpp_flags) -x assembler-with-cpp -o $(dtc-tmp) $(pre-tmp) ; \ $(DTC) -O dtb -o $@ -b 0 \ -i $(dir $<) $(DTC_FLAGS) \ I tested the patched version in my macOS machine and a linux VM and I was able to compile successfully in both (with appropriate KCFLAGS).

    Hi Pirate, For Tinker Board 2, the max loading (all connectors been connected) power is around 30W. So considering the degradation of conversion efficiency of some power supplies, we provided a conventional 19V's 45W for reference. (You can check with our user manual, https://tinker-board.asus.com/doc_tb2.html#user, page. 18.) So, if your would not connect with power-hungry USB devices, 15~20W should meet most of the usage. (without others, board only, max stress around ~10W.) And the website, it is should be the maintenance error, written too large as a reference value, which we will arrange to revision. Is 12V or 19V better? My understanding is 12V leads to more amps, so should I go 12v? --> No, 12~19V all would re convert to board used voltage, so you can just make sure the totally watt. Is it max 45W or 65W because both websites say a different thing. --> Like above, you can reference 45W or depends on real usage needs. Does anyone have a link to a compatible power supply, preferably on Amazon.ca? --> All safety compliant, and 5.5/2.5mm DC plug, 12~19V +-5% adapters should be fine. (You can find follow info from our user manual too, https://tinker-board.asus.com/doc_tb2.html#user, page. 18.) Thanks.
