New motherboard - ANX firmware won't flash.
#1
Finally got the ANX firmware update accepted using postmarketOS & Phosh, anyone else solving the same issue might want to try this first.

Just replaced with 3GB version. The wiki instructs flashing ANX firmware but:
ash: write error: Operation timed out

I have usb ssh access but not usb file manager (Thunar) access. Not sure if this is an issue?
#2
I think the anx firmware needs to be flashed from the phone directly.
#3
Yep, that's how I tried it (Sxmo & Mobian).
Phone is accessible via usb ssh, and visable in gui file manager but won't mount.
"Failed to mount 'PINE64 PinePhone' - Unable to open MTP device 001,007"
#4
if you use ssh through the usb and update part of the usb firmware the connection is broken no? Sorry if i'm misunderstanding.
#5
When I try to update the ANX firmware as directed (as root 'sudo su'), and USING the touch screen interface (NO usb connected):

Smxo = ash: write error: Operation timed out

Mobian = bash: /sys/class/typec/port0/device/flash_eeprom: Permission denied
#6
on mobian try writing:

sudo -i

echo 1 > /sys/class/typec/port0/device/flash_eeprom

Thanks for the suggestion, I had also tried that but same result.

Sorry i can't help you out. Hopefully someone more knowledgeable can help you. ?

It does sound like some permission issue, i did it on megis multiboot image, but i don't remember if it was manjaro or postmarketos that i used.

Thanks - yep, as a replacement for the original faulty motherboard I would appreciate complete instructions.
I believe there is nothing non-standard that I am doing in this setup/process.
I'm am not even sure whether the firmware is required in my case however I do have multiple issues at the moment:
Sxmo = no charging, no touchscreen, distorted gui interface.
Charging is available on Mobian.

/sys/class/typec/port0/device/flash_eeprom contains text "Write 1 to this file to initiate firmware flashing. Consult dmesg for results."

After echo 1 > /sys/class/typec/port0/device/flash_eeprom dmesg reports:
anx7688 1-0028: power enabled
anx7688 1-0028: eeprom wr 10 02 00 26 02 19 fb 00 00 00 00 00 02 02 57 90 72

anx7688 1-0028: timeout waiting for eeprom
anx7688 1-0028: power disabled

echo 1 > /sys/class/typec/port0/device/flash after booting with 'modem killswitch ON' dmesg reports:

anx7688 1-0028: boot firmware load failed (you may need to flash FW to anx7688 first)
