Gen2_6.1 = YK201C 1.0 = MM32SPIN25 #68
Comments
you do not need to identify the brand those does not matter, only the mcu model number is important, the rest of work can be done by autodetect |
only known board that have addressable led is 2.4.1 and 2.4.2 |
I think I may be mistaken on the MCU. It's likely a MM32SPIN like in Issue 38. They put a metallic sticker on this thing with some form of adhesive that is impossible to get off. I've used acetone etc. However, MM32SPIN seems to have the same blue streak and 3 fiducials and this is an earlier rev off that board anyway |
Ah it seems I was mistaken in that it's not addressable, just an rgb |
you will need to make sure your board is mm32spin05 or mm32spin06 your board have 5 led driver, so likely no addressable led is required |
So I'm pretty sure those stickers had some sort of etchant mixed into the adhesive. edit: On second thought, I suspect these were lasered off and the aluminum sticker was put there to avoid EMF/UV interference with normal operation
This board is V2.0 of this so I'd be willing to bet the MCU wasn't what changed. I could be terribly wrong though. At the end of the day whether I brick it or don't do anything with it I have the same outcome. I suppose once I get a power supply I could check some voltages |
the marking is lasered off, i can still see 3 locating dimple in the chip, which match mm32spin, but it could be again a unknown chip |
ah interesting. Thank you for finding that! I will work on getting it powered and if you add support for the spin25, I'll run whatever tests you'd like |
i will compile blink code for mm32spin25 for you |
if it worked ill add spin25 target to main firmware and send you autodetect+normal firmware |
to flash mm32spin25, the step is confirmed to be the same as spin05 incase the firmware i supply is wrong, you may need to unbrick your board at some point because ive certainly done that a couple time and now you will have to test the unstable code directly from me |
if you ready tell me i have firmware now |
blink have been sucessfully tested on mm32spin25 now, but all the main firmware have to be completly rewritten, so you will have to wait a long time |
Ah ok. I'll have to borrow a power supply from my friend to test it. Thank you very much for looking into this so thoroughly! Not only did you identify the mcu with me, you've gone out of your way to write some test firmware, locate a spin25 board, test it yourself, and update me on the issues surrounding this new chip. I really appreciate it! It's very apparent you love what you do AILIFE. |
If this is indeed a new MCU target MM32SPIN25 then this board should be Gen2.6.1 I guess. 2.5 is LKS32 .. Big thanks to @AILIFE4798 for covering the quickly growing MM32 family |
Have added this board as Gen2_6.1 to the "interactive board identifier": https://github.com/RoboDurden/Hoverboard-Firmware-Hack-Gen2.x/wiki |
@TheBestJohn if you barrow a power supply be very careful, because the hoverboard I acquired with a very similar board to this one YK190A the pins on the power supply are opposite of the other boards/power supplied I already had. The positive and negative pins should be labeled on the bottom of the board. |
I'd like to add another to the list, This one looks like YK201C instead of the A version of Issue 44's board. I'll be working on it shortly, I just need access to a power supply.
I can't identify the brand because the exterior has been abused significantly. It does have a bunch of addressable LEDs, a Bluetooth module hot glued to the case and instead of onboard xt60, a spade and barrel connector.
