My "rockpro64" is different from the public circuit diagram.

[t4_4t]

"ROCKPro64 Schematic v2.1 (Second Batch Production Release)"
http://files.pine64.org/doc/rockpro64/ro...21-SCH.pdf

Question 1)
In the above published circuit diagram (Sheet of "CODEC/Head phone")
"R225 = DNP,   R226 = 0R" is presented.

However, the result of examining my "rockpro64" is
"R225 = 10kΩ, R226 = DNP".

Please tell me whether this difference is due to the production lot or just the mistake of the circuit diagram.
*) I think that it is merely a mistake in the circuit diagram.


Question 2)
Connection of headphone-jack = "J16:pj_35A063" is obviously wrong.
*) I think that the top and bottom are connected in reverse.

Please introduce the datasheet of "pj_35A063" or present the correct circuit diagram.
I searched the datasheet for "pj_35A063", but I could not find it.

As for the signal name "HPGND / HPOL / HPOR", its connection relation can be inferred.
However, as for the signal name "PHONE_DET / MIC_IN 2 P",
since the specification of "pj_35A063" is unknown,
it is impossible to infer the correct connection relation.

My "rockpro64" is a "RAM=4GB" version, and it arrived in 2018-August.
I think that it is probably the "second batch production" lot.
