WBUS-DIP28 reset pin does not reset the Pyboard

[pythoncoder]

I can't get the reset pin to work. In case I'm missing something please could someone try momentarily linking it to Gnd to see if the Pyboard is reset (brief flash of the green LED).

I've tried it on two units and nothing happens. The reset pin on the Pyboard D itself works fine, as does the reset button. I've checked the schematics: the pin on the DIP28 should work.

If this is confirmed I'll raise an issue.

Confirmed.

It's connected to the reset line on the Tile header, but surprisingly not to the WBUS header (pin 48). I don't know if that's deliberate or not -- definitely worth raising an issue, like you say it's connected in the schematic.

Thank you for confirming - I thought I was going bonkers Issue #5250 raised.

NRST isn't connected to WBUS-DIP28 by design (and the route should not be in the schema).
It might be a bit inconvenient but DIP28 NRST can be connected to PYBD NRST by a bodge wire or, and this made more sense to the designer, handle DIP28 NRST through another GPIO.
With NRST being hard wired between PYBD & DIP28 hot plugging tiles was too unreliable.

Since the Pin on the DIP28 is la belled RST, what function does it have and where is it connected to. In any case, the Pin should be labeled properly. If it isn't the reset pin, it should not be called as such.
b.t.w.: I cannot imagine that hot swapping tiles is a common operation.

It seems that its purpose is to reset the tiles. A different name would avoid this confusion.

@jimmo I'm looking forward to the adaptor board we discussed which would fix this!
