hello @Manu512, thank you for the advice, we will take it into consideration and refine the documentation

hello @billierios, 1. are the jumper caps attached to the board? (see https://tinker-board.asus.com/download/E22240_Tinker_System_2_EM_V2_WEB.pdf page 17 section 7 'power on header and maskrom jumper') 2. is it possible for you to screenshot the access denied error? 3. have you tried using balenaetcher to flash?

hello @michiksdjfklsdjfl, the steps are correct, is it possible for you to screenshot after every execution of the commands? sudo chmod a+x ./rt_UAC_utility sudo ./rt_UAC_utility --force 0x49F6_ALC4030U_ASUS_Tinker_Board_0x0BDA_V13_20220718.rfw --reset RST_2_ATTACH sudo ./rt_UAC_utility --status --reset RST_2_ATTACH after the driver installation, reboot and use these two command to verify: sudo reboot sudo ./rt_UAC_utility --status --reset RST_2_ATTACH

hello @magixx, yes, still working on it and will keep you posted

hello @michiksdjfklsdjfl, 1. please open the terminal, execute the command below and send us the screenshot: lsusb 2. please provide us steps to duplicate the issue and the audio file used; we have not observed the issue on our side and would like to reproduce the issue 3. does the hissing sound linger when occurs or does it only happen when you play the audio? if it's possible, could you send us the audio record with the hissing sound so we can narrow down the rootcause

hello @michiksdjfklsdjfl, 1. what's the hardware version of the boards? (it's printed on the back of the product e.g. 'Tinker Board S R2.0 REV 0.1') 2. what's the audio firmware version you've updated to? 3. what's the os version you're using? (debian/ android/ ?)

hello @lloydhussell, for more about can-utils: https://github.com/linux-can/can-utils it's supported on android debug build, it's not available on user build

hello @wahaha, bootargs can specify the location of the ramdisk (initrd); however, for initramfs, you need to load the initramfs into memory and pass its address to the kernel. If the initramfs is built into the kernel image, then there is no need for separate loading or bootargs configuration

hello @ryo, since you have sd image ready, you can flash tinker board 3's emmc in ums mode. please keep the sd card in the board and 1. switch all the dip switches to off 2. connect tinker board 3 and laptop with micro usb cable 3. power on, open device manager and see if the board is recognised as 'ASUS Tinker UMS USB Device' 4. use balena etcher to flash it

hello @wahaha, unfortunately there's no specific config to define ramdisk partition. verifying and loading kernel and ramfs both by default start from fit image. to load ramfs only you will need to use a command such as ex2load or fatload manually.

hello @ryo, have you adjusted the dip switches to 1 and 2 so the board is in emmc mode? (on the other hand if you set them to 'on', it would be in sd card mode)

hello @shizimi, no, it will not be able to power since it needs 12v - 19v power via dc jack. please refer to the block diagram ch.1.6.1 on page 12: E22692_Tinker_Board_3_UM_WEB.pdf (asus.com)

hello @shizimi, the user manual/ quick start guide of tinker board 3 & tinker board 3s is released: https://tinker-board.asus.com/download/E22692_Tinker_Board_3_UM_WEB.pdf

hello @wahaha, please add the overlay to /boot/config.txt, save and reboot and see if the overlay comes effective sudo vi /boot/config.txt overlay=console-uart0-overlay

hello @shizimi, we're planning to update the documentation next week, i'll put the link on here once it's ready. sorry for the inconvenience
