OrangePI PC: Header Pinout

mcc

Hi,

this morning I did a closer look at the 40pin header layout in the user
manual of the OrangePI PC while comparing it to the
Allwinner H3 datasheetl.

I came accross
CON3-P16 PC4               PC4
CON3-P18 CAN_RX        PC7

According to the Allwinner H3 datasheet PC4 and PC7 have one function each:
PC04 I/O DIS Pull-up NAND_CE0    -           -           -     -
PC07 I/O DIS Pull-up NAND_RB1    -           -           -     -

In that datasheet I canot find CAN_RX mentioned. I dont know, of what use both NAND-related functions
of these two pins are.
On the other side "CAN_RX" and "CAN_TX" are mentioned in the Allwinner A20 datasheet, for other
pins though.

What is the use of these NAND_* functions?

Is the pinout in the users manual ok?

Thank you very much in advance for any help!
Best regards,

This should answer your question.

Hi crazykill,

thanks for the picture.
Unfortunately the pins in question, PC4 and PC7, are not explained...

Best regards,

Pin 8 and 10 for RX and TX.And for those two pins PC4,PC7 are normal input pins according to the wiringPI library.
