Link delay 0 beyond neighborPropDelayThresh; not AsCapable

[YiYuan111]

Hello, I have two development boards for gPTP test. However, the first error was reported.
The link_delay and turn_around values are both 0. Here are the logs for both ends

gPTP code was moved to dedicated repo AVnu/gptp, so you can try to post it there (and describe a bit more your setup)
