I have noticed something else. When I reset the LAN8720 by pulling the nRST line low, the 100mbit led goes off. Then it does not seem to respond anymore. After that the SMI registers read 0xffff. When in a running situation I reset the LAN8720 with the control register 0, bit 15, it works. So what i...

https://github.com/espressif/esp-idf/issues/2564 ? I'm sorry, but this seems no effect. I have compiled my project with both 3.1 and 3.3 IDF framework version, but the issue remains. Only difference is that in 3.1 it's get stuck in the "Timed out waiting for PHY..." loop. In 3.2 and 3.3 this is not...

Hi all, I have a ESP32 connected to a LAN8720 chip on a custom PCB. This all works fine. And we use it to send in sensor data to the Internet. However we noticed that sometimes in the field the LAN8720 stops responding. This could be after a week, sometimes after 20 min. So it's random. What happens...

Hi All, Hope someone can provide me an answer to this. I have successfully applied the Ethernet-to-WiFi example. (Great example BTW). But now I have the following question: Is it possible to have the Ethernet work stand-alone next to the WiFi forwarding? To explain more: the example pipes the WiFi c...

I assume top to bottom right? With top being the latest function?

The top row says: What does this tell me?

Hi follow ESP32 users, I have the following coredump: ==================== CURRENT THREAD STACK ===================== #0 0x4008fecf in esp_core_dump_write_flash_padded (data_size=12, data=0x3ffcab00 \"\", off=0) at /home/peter/esp/esp-idf-v3.1/components/esp32/core_dump.c:291 #1 esp_core_dump_flash_...

That sounds like reasonable at this point. So I have the pins checked, and they seem OK. Also, I have done another test. Just let the SPI code run in the app_main as a loop like so: void app_main(void) { // Analog spi_device_handle_t spi_handle = SPI_init(); delay(200); while(1) { SPI_read_temp(spi_...

These outputs are from "make monitor". I also dump the core to flash. So I can read it out later. It says different things, on different occasions, but this is the latest: ================== CURRENT THREAD REGISTERS =================== pc 0x400d41cf 0x400d41cf <heap_caps_init+23> lbeg 0x0 0 lend 0x0...

Hi all, I have a weird issue. I am using SPI to read out some temperature sensors. The code I have to do this runs fine on one ESP32, but crashes on another ESP32. Both hardware are the same. To give some idea, here is my code to init SPI: spi_device_handle_t SPI_init(void) { ESP_LOGD(tag, ">> test_...

Hi all, I have an ESP32 running on a custom build PCB. However sometimes the program crashes with the following error message: Interrupt wd$ timeout on CPU0 PC 0021 : 0x0003A0 088e : 0x3fa3 : 0x3fa6A3 f0de : 0x0001A5 0001 A6 0000 : 0x0000A8 0001 : 0x3434 : 0x000aA11 0001 : 0x3f0dA13 0001 A14 fc24 : ...
