Update wiki for new Ploopy Lefty Classics shipping with rev 1.005

[dongle]

Thank you for all of your work making a durable, reparable, customizable, libre trackball. I'm absolutely loving my Ploopy Classic Left-handed trackball, but I almost flashed it according to the wiki using the rev1 configuration before remembering that the black PCBs you showcased on reddit had rev 1.005 printed on them. It would be helpful to put a new caveat in the wiki for that and mention that you can assign a reset key in via to try to recover in the event of a mistake. I'd do it myself as a PR but I figure you have better info re: which Lefties shipped with which revision and if there are tricks to tell them apart without opening up the Ploopy.

I made the mistake of flashing the rev1 drag_scroll, and even sillier, with drag scroll on at boot. Is there any way to enter the bootloader now? Holding the left-most button (or any other one) while plugging in doesn't work anymore 😭

What revision of ploopy do you have? You'll need to get access to the PCB to be able to use a hardware means to get into bootloader.

What revision of ploopy do you have?

The PCB say L1.005.

Thanks, could you please elaborate on this?

On the corner of the pcb near the MCU there are these holes you can bridge with tweezers whilst plugged in, to
Get to bootloader mode.

Unfortunately the new lefty PCB doesn't have that: https://redd.it/purfmg

I tried bridging pairs near the XY mark both during and after plugging in and neither worked. The new lefty semantic haven't seemed to be uploaded either.

I'll wait for crop octagon to chime in with the correct answer, but the brute force way may be to short (carefully!) the ground and reset pins on the atmega:

Thanks, what's the worst thing that can go wrong while trying to short those pins?

Well they have VCC in between, so there's a possibility of shorting GND to VCC, which might kill the voltage regulator. It's also probably possible to kill the chip.

I'd recommend trying emailing "contact (at) ploopy [dot] co" if you haven't already, they might not have seen this issue.

I contacted support and the solution was to flash a new bootloader, and I could finally enter bootloader mode again. The wiki doesn't seem to be updated yet though.
