Ethernet example fails to obtain IP with KSZ8041 on ESP32 in ESP-IDF v5.5.1 (IDFGH-17018) #18064
Description
Answers checklist.
- I have read the documentation ESP-IDF Programming Guide and the issue is not addressed there.
- I have updated my IDF branch (master or release) to the latest version and checked that the issue is present there.
- I have searched the issue tracker for a similar issue and not found a similar issue.
IDF version.
v5.5.1
Operating System used.
Linux
How did you build your project?
Command line with Make
If you are using Windows, please specify command line type.
None
What is the expected behavior?
The Ethernet interface should behave the same as in ESP-IDF v4.4.8:
- PHY is detected
- Link comes up
- DHCP client receives an IP address
- Network communication works (ping, ARP, etc.)
What is the actual behavior?
- PHY is detected successfully:
ksz80xx: auto detected phy KSZ8041 - Ethernet interface is attached to the netif
- Link status reports UP
- DHCP client starts
- No IP address is obtained
- After some time, the interface reports an IP lost / timeout condition
- There are no fatal errors or crashes.
Steps to reproduce.
Run examples/ethernet/basic on v4.4.8 - confirm it acquires an IP
CONFIG_ESPTOOLPY_FLASHSIZE_4MB=y

More Information.
- Chip: WROOM-32UE
- The issue is reproducible and deterministic on our custom hardware.
- Hardware has been validated in production with ESP-IDF v4.4.x.
- The problem was observed when migrating three firmware versions from 4.4.7 to the current stable release (5.5.1).
