Serial console

[hmuller]

I have the PBP and the serial cable sold in the store. The serial console developer guide referenced in the store gives instructions for use with the original Pinebook, which uses a different SoC.

The file /sys/class/sunxi_dump/write is not present on the PBP rk3399 based system.

So it is not yet clear how to use the serial cable with the PBP.

UPDATE

The wiki defines how the serial cable is to be used. The bottom of the PBP must be removed, and a switch must be toggled. See the wiki for further guidance.

I have found that once the switch is flippedd, in the default build I can use serial condole to see u-boot messages.  I get as far as the login prompt,  and then don't seem to be getting any response .  On Ayufans' bionic lxde running from the sd card,  I can't get any response at all on the serial console.  Are their some progs/services that need to be enabled or disabled?

Unclear at this point. I tested cable on the Debian desktop installed on microSD. Tomorrow I will look at the default installation on eMMC, and then at ayufan's bionic on microSD. Will let you know the results.

UPDATE: The default installation on eMMC emits data properly on the serial cable. Ayufan's bionic on microSD also emits data properly, but it stops at a certain point as Ayufan has disabled bootconsole [uart0].
