Hi,

Is the Pinebook Serial Console usable with the Pinebook Pro?

On mine PBP, when I used the Pinebook serial console, it seems to lead to eMMC not responding: when plugged-in from cold boot, I got DDR initialization then it hangs; if I plug the jack after DDR initialization, I got eMMC timeout.

Here is a sample serial output, from a cold boot:

Code:

Then it hangs indefinitely. The power LED stays off.

When attaching the jack after u-boot load from eMMC:

With the jack plugged-in but the USB plug not attached to a computer, it boots normally.

What am I doing wrong?

Perhaps nothing?  There are problems reported with using the Pine64 cable with the PBP.

https://forum.pine64.org/showthread.php?tid=7746&page=2

According to this page, https://nixos.wiki/wiki/NixOS_on_ARM/PIN...al_console :

"It is not recommended to connect the serial adapter to pin 10 (RX) while booting, as this often causes the board to hang early in the bootloader."
