August 22, 20251 yr This is a sidebar/urgent request for help. I was previously able to install Armbian noble on my YY3568 board thanks to instructions from these forums (https://forum.armbian.com/topic/49775-board-bring-up-youyeetoo-yy3568-rockchip-rk3568/). I now need to use the board for a Debian project to help a friend that lost their backup, and am unable to reproduce the instructions in that post to empty the eMMC and enable SD boot. The poorly written/flawed instructions in this post involve loading a config file into RKDevTool, writing loader, parameters and uboot, then there is a line about "destroying partitions by writing wipe_part" (a file you can download in the post), with no clarity or description of how to do this. The steps then move onto flashing another loader to the board. I have done all of these steps in MANY different adaptions and versions and it is always unsuccessful because whatever portion involving the "wipe_part" is missing from the original steps. I am hoping that someone else whose board uses similar procedure sees this and can correct the instructions and make SD boot possible again. It's really aggravating that my board is being held hostage to this - the person who wrote the instructions has worked on other projects with similar steps and others have had the same issue with their incomplete/incorrect instructions in those posts, and so far will not reply regarding this. I've tried 4 different versions of RKDevTool and worked for around 7 hours on this so far with no success. I'm hoping someone else can come save me!
August 22, 20251 yr I never used RKDevTool because I'm on Linux. I understand the instructions as follows: Download RKDevTool, Wipe_part and Clear_EMMC_yy3568.zip from the links in the original post. The zip contains the config for RKDevTool from Nicolas. The included file path will not work on your system. You have to adjust these that uboot.img, miniloader.bin and parameter.txt from the Clear_EMMC_yy3568 are used and the separately downloaded wipe_part. I assume that at the next boot some partitions on EMMC are cleared and in consequence booting from SDcard is activated.
August 22, 20251 yr Author That part of the instructions is clear. It's the steps involving the "wipe_part" file that supposedly erases partitions on the eMMC and the flashing of the second loader file that I can't make out. It looks like the instructions were edited to make them unusable. Nicolas has had the same issue in the H96 subforum with bad instructions and people asking for help due to the lack of clarity. I was able to make the board boot from SD card after flashing it with the YYT provided Debian 11 image, but only to Armbian Noble. No Debian distros work. When a Debian SD is inserted, the board boots then enters a systemd-devd shell with error messages about a UUID not being found. All Debian images do the same, I think it has to do with the eMMC memory not being seen because it is still formatted and not cleared. I have never seen a shell like this. Armbian Noble still boots properly, but only Noble. I need a Debian minimal distro in order to install OpenMediaVault and save my friend's files.
September 3, 20251 yr You will need to flash an android "Update image" first, into EMMC, to go back to factory defaults. https://wiki.youyeetoo.com/en/YY3568/unpack https://drive.google.com/drive/folders/11BrqafnkEyFaM-D0gaPFhrmnRM47JAEU MaskRom mode upgrade firmware First of all, make sure that you have entered the MaskRom upgrade mode, and then perform the following firmware upgrade operations. Upgrade firmware in loader mode Open the AndroidTool tool, the board enters the upgrade mode, and a LOADER device will be found on the AndroidTool. Then perform the following upgrade firmware operation.
