Note: The above screenshot only has a few of the labels highlighted, in fact all of the component values on the silkscreen are not with their schematic values.

Yes, this is a mess, - as there also 'real' errors like https://github.com/openvizsla/ov_ftdi/issues/42 . I'll discuss this with laforge , let's postpone this ticket towards the end and at least not before #5068.

• removing all values (like 12Mhz, 120 Ohms) from the silk screen.
• keeping only the designators (R12, C55, ...) whihc hopefully are automatically generated

This reflects what we do in the "native, non-inherited" osmocom designs, too.

• [martin?] checking + [cibomahto] fixing all the labels next to pins/gpios, where we also know of at least one error (1V2 vs 5V)

affirmative.

Me still searching for further errors on the pin header like the one known (see above).

To aid in your search, here are snaps of all the text labels that are on the board, which are not linked to a component.

Addressed here: https://github.com/openvizsla/ov_ftdi/pull/46/commits/c375a9521479726700d115124904ca306fbb89ec

• Remove component values from silkscreen
• Remove pin # labels and tick marks from silkscreen
• Verify that component designators are located next to the correct
  parts
• Fix 1v2 and 5v labels on P4

mschramm if you find any more errors, please let me know.

Thanks, looks good so far!
But somewhat even before the pin numbers on the THT headers went to ... erm, Arial ?! ;) Let them become calibri again (or a simple vector font).

It looks like they were previously vector font, and got switched to the default truetype font (Arial). Updated here (and corrected the orientation of the ones on P3):

https://github.com/openvizsla/ov_ftdi/pull/46/commits/c6dcce2190937fdf3b5a1fd5100a4f517a3d7eca

These pin numbers do happen to be attached to the header footprints

All THT header checked, only one error remaining:

Pin 19 of P3 is designated on the bottom side as TDI, which is wrong, it rather is connected to TDO. Please change this label on the bott side to TDO (lower case: "tdo").

Corrected here: https://github.com/openvizsla/ov_ftdi/pull/46/commits/eb9e5777476d5e0926ac9fa4d2bf60baa5e07f6d

solved, thanks
