rte/v1.1.0/specification.md: Describe GPIO pins purpose

No description provided.

We will have some duplication with: https://docs.dasharo.com/unified-test-documentation/generic-testing-stand-setup/

Maybe we should link from generic test setup to the document you have just modified?

Especially that you are adding now info on power LED, which is not yet covered in generic test setup at all I think.

Ohh didn't know that it is already described elsewhere. But still the generic testing stand does not include all the pre-defined OC GPIOs. It is a duplication to some extent, however not entirely.

Sounds like a good idea.

It is not covered, but it should be. I will update the PR.

@macpijan Now that I look at it again, we have swapped RST and PWR_BTN pins. Per schematics (and my changes in the PR):

PWR_BTN is pin 6 and RST is pin 5, while we use the following in the testing stand setup:

J11 pin 5 PWR_ON#
J11 pin 6 RST#
J15 pin 1 GND

Per the config https://github.com/3mdeb/RteCtrl/blob/master/config/RteCtrl.cfg#L69 we also have the RST first (409 / GPB1) the PWR_BTN (410 / GPB2). osfv_cli seems to use good pins, because it uses IDs as in RteCtrl.cfg:
https://github.com/Dasharo/osfv-scripts/blob/main/osfv_cli/src/osfv/libs/rte.py#L20

Now I wonder how many setups got it wrong...

f60178d add the links to RTE spec and add PWR LED signal connection.
9151138 fixes the PWR and RST pin numbering.

@macpijan please review again
