Ox64 documentation mismatches - ukoda - 11-28-2022

Hi guys,
  I am developing a board to use the Ox64 for a commercial application and while mapping out the planned pin usage and creating a KiCAD part I found a mismatch between the four documents I was referencing:
  • PINE64_Ox64-Schematic-202221007.pdf from the wiki.
  • PINE64_Ox64_placement-Bottom-202221007.pdf from the wiki.
  • BL808_DS_en_1.1(open).pdf from the wiki.
  • Ox64 Pin Assignments spreadsheet, probably from the original announcement blog.
The last one can probably be ignored as nothing on it matches anything else but if anyone see it posted anywhere they should probably have it pulled down to avoid confusion.

I have found five issues so far:
  1. Pin 4 on the schematic is labelled as GPIO12 but on the bottom placement is labelled as GP21.
  2. Pin 5 on the schematic is labelled as GPIO13 but on the bottom placement is labelled as GP31.
  3. Pin 6 on the schematic is labelled as GPIO41 but on the bottom placement is labelled as GP14.  There is no GPIO41 pin on the BL808C datasheet.
  4. Pin 7 on the schematic is labelled as GPIO40 but on the bottom placement is labelled as GP4.  There is no GPIO40 pin on the BL808C datasheet.
  5. Pin 12 on the schematic is labelled as GPIO20 but on the bottom placement is labelled as GP2.

I am guessing that:
  1. Pin 4 is actually GPIO12.
  2. Pin 5 is actually GPIO13.
  3. Pin 6 is possibly GPIO5.  Low confidence in this guess.
  4. Pin 7 is possibly GPIO4.  Low confidence in this guess.
  5. Pin 12 is actually GPIO20.

Couldn't find anywhere official to report these issues to so posting here in the hope the right people see this and can update the files on the wiki.

The current Ox64 info posted on wiki page is the prototype board version. The production version will be posted up on this week. The GPIO40 and GPIO41 are 32KHz xtal pins that can also be used as GPIO.
