Pinephone mainboard v1.2 documentation update?

[scholbert]

Hi!

This thread may go out to the pine64 crew...
Maybe it would be possible to get an update on the mainboard placement documents.

Code:

PinePhone mainboard bottom placement v1.1 20191031.pdf
PinePhone mainboard top placement v1.1 20191031.pdf

There's still v1.1 available in the wiki, but it would be nice to get these documents referenced to the v1.2 boards.

Another thing to mention is, that it would be really nice to know about the exact position of the testpoints.
This might be helpful for debugging and low-level programming... or weird addons.

So far i made a list with the schematics as a reference.
v1.2 mainboard bottom:

Code:

in the middle nearby the mpu (U1, upper left):
T500 -> CPUS-UTX  (AR100 UART TX, disabled in crust, used as WL-PMU-EN)
T501 -> CPUS-URX  (AR100 UART RX, disabled in crust, used as WL-WAKE-AP)
T502 -> HDMI-CEC
T503 -> FEL  (pull low to enter FEL mode, USB-Boot)

next to ANX7688 (U1304):
T1300 -> ANX_CSDA
T1302 -> ANX_CSDL
T1502 -> GPIO0 (ANX7688

v1.2 mainboard top:

Code:

beneath J1101:
T1100 -> CTP-RST
T1101 -> CTP-INT
T1102 -> TWI0-SDA
T1103 -> TWI0-SCK
T1104 -> GPIO0-LDO (VCC-3V)

above J1200:
T1202 -> POWKEY
T1203 -> VOL-
T1204 -> VOL+

next to J1300:
T1 -> USB0-DP
T2 -> USB0-DM
T3 -> DCIN
T4 -> VBAT

in the middle nearby the modem (U1500):
T1503 -> HTXCN
T1504 -> HTXCP
T1505 -> HTX0N
T1506 -> HTX0P

T1600 -> 4K7_PD
T1601 -> USB_BOOT

The group of the HDMI signal pairs are just a guess, as we don't know the position yet.
The only reference i found in the wiki were the USB_BOOT (Modem) pins...

The craziest thing ever would be, if the board-files (e.g. gerber-data) could be shared...

Best regards,
