On my system it’s custom, dunno about the others in this thread. Given that in two posts the 8720 registers are identical, and on two systems the TXD0 & TXD1 pins go low and remain that way for the duration, to me that suggests either a problem in the MAC, or a perpheral conflct in the ESP32 that af...

Here's a verbose dump of my system ... it's the ethernet example, with verbose logging and the appropriate Example Config for my hardware.

I'm having the same problem

Hmmm ... that would make sense -- I had not thought of that. I don't recall see the manuals say that the SDIO interface goes to 1.8V I/O levels in that case (just that VDD_SDIO is sourced from the internal 1.8V regulator) -- but that would make sense. Yes, I figured there was a weak pull-up issue in...

Hi All. Am using a SparkFun ESP32 Thing as a development platform, have been successfully working with it for 6 weeks or so. The Thing is plugged into our own board, which has stuff like an SD Card socket, Ethernet PHY, I2C peripherals, etc. During that time, GPIO12 (which is a bootstrap pin that co...

Thank you -- I suspected something like that, but didn't know where to look.

Thanks again,

Hello. This is my first post. I am able to successfully build and run the hello_world application on a SparkFun ESP32 Thing module (26MHz main xtal). However, I observer that whereas these lines in the example: for (int i = 10; i >= 0; i--) { printf("Restarting in %d seconds...\n", i); vTaskDelay(10...
