problem:

I have used espressif esp32s ethernet example trying to build code of basic and binary is successfully generated, now while executing it is throwing error as given below :

hardware/software

chip used esp32-wrover-1

idf version -release/v4.2

build sysytem - msys/MINGW32

power supply - usb

Rebooting...

Do you use any specific development board? It seems to be the ESP32 EMAC is not properly configured. Probably not properly clocked, but I need to know your hardware configuration so we could move forward.

Thanks

We are using NLG1200 board on which esp32 chip is mounted. Image NLG1200 i have attached below

Thanks for the inputs. Frankly speaking, I have no knowledge about NLG1200... Did you check the Ethernet configuration align with actual hardware? For example, proper GPIO is selected?

Hello, could you please guide me, what and all will be the configuration to execute ethernet example which is already given in sdk/example/ethernet/basic in idf version release/4.2
For that from idf.py menuconfig what and all should be enabled

kesha.modhia, as I said, please double check that the Ethernet basic example GPIO configuration aligns with your actual hardware. You've already sent screen shots of that in menuconfig. I don't have schematics of NLG1200 neither the hardware itself. Therefore I cannot guide you in this manner. I can only guess what's wrong. However, based on described symptoms, it seems there is no RMII REF CLK which could be caused the PHY is kept in reset which in turn is caused by incorrect GPIO setting. Please also make sure you select the PHY part number.

Okay i am sending you some screen shot of the schematic on NLG1200 board on which i want to enable the ethernet
In that board i am trying to run ethernet basic example, and according to schematic i have selected gpio19 for phy reset,previously it was gpio5. Correct me if i am wrong for this
