Hi Espressif Systems Developer,

We are using ESP32-WROVER-I module into our development boards in which we are using Ethernet Interface. In that board we have both Internal and External Flash Memory on same interface except CS GPIO.

We are using ESP32 IDF 2.1 reference for our development purpose and Ethernet is working fine with Flash Boot Memory as Internal Flash Memory.

But, We we changed EFUSE settings and make external flash memory as Flash Boot Memory at that time Ethernet is not working and we are getting below errors while initializing Ethernet.

I board_init: board_phy_device_power_enable_via_gpio: 170: phy_device_power_enable(TRUE)

But, If we take ESP32 IDF reference as 3.0 RC1 then Ethernet is working fine with external flash memory as boot flash memory.

So, Please let me know if anyone has any idea regarding changes into ESP32 IDF to make it working into ESP32 IDF 2.1

Hi,

Does anyone has any idea or clue regarding this issue?

https://github.com/espressif/esp-idf/co ... s/ethernet

There are not that many changes to Ethernet component so check them

Thanks for Response.

But Ethernet was working fine when bootable flash memory is configured as default module's internal 4 MB Flash Memory.

When we switched bootable memory as external memory at that time Ethernet is stopped to work into ESP32 IDF 2.1 SDK though it is working fine into ESP32 IDF 3.0 SDK with bootable memory as external memory.

So, Would you please let me know is there any specific patch or change to resolve that issue into existing ESP32 IDF 2.1 with bootable memory as external flash memory instead of module's internal flash memory? Then it will become easy for me to apply changes w.r.t. that only.

Hope you will understand my concern and let me know if still need anything from my side.

You don't want the other bugfixes? Have you notice common theme yet "stop using 2.1"? Just because it is "final release" don't mean it is good.

Hi WiFive,

Understood your concern regarding to switch to 3.0 RC1 or stable IDF.

But, Right now we are developing one framework by taking some components from ESP32 IDF 2.1 SDK when we started to develop our framework. So that we just adopted freeRTOS, HAL driver and few application components from ESP32 IDF 2.1 not complete ESP32 IDF 2.1 SDK.

Also, We had made few changes into existing ESP32 2.1 components as per our requirement.

So that Right now, It's difficult for us to update each and every components by comparing it and need to retest all functionality again if we switch from ESP32 IDF 2.1 to 3.0.

That is why I just to know if any specific patch or bug fix for Ethernet issue then it will be easy for me to adopt into our existing framework which is based on ESP32 IDF 2.1 components.

Let me correct if I am wrong at any point.

Hi Ritesh, please mention the IOs you use to connect Ethernet PHY, and IOs used by the external flash chip.
In addition to that, please attach the output of 'espefuse.py --summary'.

Okay, so you seem to be using LAN8720 PHY, and there its ID registers always read as 0xffff. This likely means that the PHY has not powered up. Please check if the PHY power pin from the IO expander to the PHY actually goes into the correct state.
Another thing: do you have a logic analyzer (a low frequency one will do)? If yes, please check both the I2C bus used for the expander, and the SMI interface between ESP32 and the PHY (if they are not on the same pins?)

Hi ESP_igrr,

I think there is no any issue into Hardware Side as Same Hardware is working fine with ESP32 IDF 3.0 SDK as we had checked earlier.

So, We had checked and compared Ethernet Related Components + PHY registers and EFUSE related changes between ESP32 IDF 2.1 and ESP32 IDF 3.0 and not found much changes to break that functionality.

Ethernet was working fine when We were using Internal 4 MB SPI Flash as boot-able memory. Also, We are using same lines of interface for external flash memory except CS which we are using GPIO33 for external flash memory connectivity.

So, When we switched from Internal Flash memory to External Flash Memory as boot-able flash memory at that time Ethernet stopped to work and getting that type of errors continuously.

So, I don't think any error into Hardware Side as it was working fine with Internal Flash Memory with same Hardware.
