TS-101 enter boot loop on USB-C PD (QC-92)

[PaulKissinger]

Describe the bug
TS-101 enters bootloop after 3 seconds (PD-Debug mode 6) with connected tip. Without tip, TS-101 boot regularly.

To Reproduce

1. Plug USB-C cable into TS-101
2. Wait 3 Seconds
3. See error --> Enters reboot loop

Expected behavior
Boot without reboot loop

Additional context

Eugh; I dont see this here on my PD supplies.
Do you have any means of capturing the PD traffic?

[PaulKissinger]

Sorry, i have no idea how to capturing PD traffic.

I'll test prebuilds, if you have an idea.

same with Baseus CCGAN2P-L01. On charger w/o PD ts101 boots normally

_{sorry for my english}

I'm seeing something similar using a ugreen power brick (brick does 130W max).

With the default firmware, everything works, but ironOS reboots after about 3 seconds on.

I've captured the PD negotiation (I think, assuming my dodgy cable assy is working).

Side-by-side logs of the PD negotiation are here: https://docs.google.com/spreadsheets/d/1SvuCWFnzG3vurIfFmuho2cohFiriwjAlfsj0Mu-qEQo/edit?usp=sharing

'Combined' sheet, the iron os starts column J.

Iron is the TS-101 flashed with 2.23rc1.

Looking at the logs, I can see this for IronOS:

Without knowing anything about the protocol, it looks a bit like the ironos might be requesting mode a bit agressively without any response from the soruce?

TS101
update to v2.23-rc2 boot loop wo any chance enter in any menu
update to v2.23-rc2 boot normaly, but after press button "A" reboot
back to 2.22 all works!

Tried PowerBank from Baseus and a regular charger
All with PD support
