If you think about this: I'd say this is release notes for the Debian OS release, not for hardware revision. I've also found this: But this is drawing and schematics, again without release notes about the differences between the hardware revisions. Thanks @tooz

@tooz We've: * installed software from official debian repository * updated default network netplan configuration * copied our binaries Nothing that would affect boardinfo. btw, /proc/boardinfo content on both boards is: Tinker Board 2S - 16GB however, /proc/boardid on "master" board is "1", but on new board is "3". Just to mention, restoring "master" image to TInkerBoard R1.02 still works properly.

During the production, we create the master image (based on Debian 11, v3.0.20) on one tinkerBoard 2S, and then clone it on other boards. That worked for some time, until recently it stopped working, meaning that restoring the same image does not end up in working/bootable TinkerBoard 2S device. Only thing we found is that new boards are TinkerBoard 2S R1.03, but the master image was created on TinkerBoard 2S R1.02. @tooz Is there a way to make the image work on all hardware revisions? Please check the photos below for revision info:

@tooz thanks for quick responses and valuable support you're providing. Maybe I'm checking it on wrong place, but those are release notes for Software OS releases, right? I was asking for release notes for hardware revisions, ie. changes in hardware between the different revisions of PCB.

Hello, Are there release notes available for TInkerBoard 2S board, to check what was updated/upgraded/fixed between the revisions. We have in production boards, some of them are marked as R1.02 and some of them are R1.03, and we were wondering about the difference now. Thanks @tooz (or anybody else of course)

@tooz thanks for the prompt response. Tried and tested it, and yes, it solved our issue. ?

Hello, We're having issues with reading date&time from RTC clock. Battery is connected, voltage is measured and is ok. We can set the date&time in RTC clock using command "hwclock --systohc" as you can see in screenshot below: But our issue is that after the reboot, only the date is read from RTC clock. After the reboot, time starts every time at 00:00:00 even though it was written to RTC before the reboot. This is plain vanilla Debian OS and we're having this issue consistently on more than one device. Any ideas? Thanks a lot.

Hello, Is there any way to read voltage level of the installed CMOS battery within the Debian OS? Purpose is to signal the operator when there is a need for battery replacement before it becomes dead and unusable. Thanks

I can, just to know the behaviour, but in production we deliver it to customer without the SD Card with the OS on the eMMC ?

I just got and tried a new, second one (same model, Tinker Board 3N). Removed the jumper cap, plugged into the mac and it immediately recognized and works like a charm. Looks like the first one needs to be RMA. Thanks

Thanks for all the great feedback. There is always an option it's a faulty one.

I'm not sure I understand the last question, but I've never "used" the board in term of booting the OS. As soon as I plug in the power supply, red led turns on. It was on also before I've removed the mask2 jumper. So, it's always on when I connect the power supply, no matter if USB cable is connected or not.

I've attached the latest setup photo for reference. Red light is there, USB-C -> USB-A, but nothing detected by Win, and nothing in device manager.

I've done all that, both jumper caps removed, except Macbook does not have USB-A port, so have to use USB hub for that. Also tried on Windows, which now does not recognize anything at all ?

Thanks for really fast answers. Unfortunatelly... still nothing. So, I've removed jumper from Mask2 pins. What about the Recovery pins, should I have the jumper there ON or no)? And also the Mask1 dip-switch?
