Thanks for replying again. I did read that thread and many others on this forum about PD and other topics. I just re-read part of the thread and especially Jack’s answers, but I couldn’t see anything about what I asked.
To be sure, I mean about this: NVMe Boot Loop (Power) and this: ROCK5 Android12 Bringup Status Update and this: ROCK 5B Debug Party Invitation
This answer from Jack is also relevant: ROCK 5B Debug Party Invitation
I think this message from the topic you linked also mentioned that work was done to try to add PD negotiation support to u-boot, but was removed again: Rock5 does not work on most PD power supplies
You can see that in this branch: https://github.com/radxa/u-boot/commits/stable-5.10-rock5
TypeC and PD support was added on July 28th, then reverted on August 2nd. On September 13th the console was disabled (presumably to make u-boot spend less time so the kernel can start PD negotiation before the power cuts out). The latest commit seems to be from October 31st, but no word on when PD negotiation will be back in that branch of u-boot. If I’m not mistaken, that’s the u-boot we are using for the Rock 5B.
Anyway, long story, but I’m wondering what the status/estimates are on PD negotiation support in u-boot. So if someone from Radxa can clarify that I would very much appreciate it!
