What happened ?
On the newest iOS version 26.3 and ever since the release of iOS 26, the success rate of obtaining a IP Address from the built in DHCP server is about 30%.
How to reproduce ?
Upload example to a nrf52833dk, plug into an iPad or iPhone running iOS 26 and the ip address won't show up most of the time; in settings->Ethernet->TinyUSB Device.
Debug Log as txt file (LOG/CFG_TUSB_DEBUG=2)
I can't currently produce logs as I'm on a custom board.
Screenshots
I think it might be that the iPhone requests an ip address before the usb device is fully ready and then never asks again. Similar to this potentially #3445.
I've got the issue on both a nrf52833 based board and an esp32-s3 based board.
However I don't see this problem at all on a RP2350 based board
