I've got a project we're working on where we are implementing a hardware ID process, using the ADC and a GPIO for a vref. This is an ESP32_WROOM_32UE on ESP-IDF 4.3.7

Essentially we have a voltage divider that is on SENSOR_VP (GPIO36/ADC1_CHANNEL_0) and GPIO_13

The help text in menuconfig for "Memory allocation strategy" describes the strategies:

"Internal DRAM memory only" vs. "Either internal or external memory based on default malloc() behavior in ESP-IDF"


Unfortunately, Espressif has broken the help text for menuconfig in vscode plugin, so that ...

What is the difference between CONFIG_MBEDTLS_INTERNAL_MEM_ALLOC and CONFIG_MBEDTLS_DEFAULT_MEM_ALLOC? This doesn't seem to be explained anywhere.

That definitely made a change, but still not quite working as expected. Here's the logs:

You can use custom configuration for OPENOCD, by using the command "ESP-IDF: Select OpenOCD Board Configuration" which have different presets or even custom configurations.
Also, when you flash via JTAG you should be asked if you want to start OpenOCD.

For debugging, I recommend you to look at ...

I'm not using a dev board. We have a production device with JTAG built in. I can flash using JTAG, but that's it. I'm dying to figure out how to do anything else with it, especially monitoring and debugging.

What's really frustrating is there seems to be no way to configure openocd to run ...

Was led here via an Espressif support rep, but had a lot of issues getting this to work. Even the claim of the code snippet from ESP_ondrej doesn't make sense, as that code doesn't appear anywhere in any example within any version of the IDF that I could find. But even using that code within the ...

I've contacted Espressif support and made some progress on this. Higher prio number equals higher priority, where I assumed a lower number equaled a higher priority. This strange since typically when talking about priority, a lower number equals a higher priority. e.g. 1 is the greatest priority ...

We're adding a w5500 chip to one of our long established pieces of hardware. I've got everything working correctly, but despite the interface priority of the w5500 being the default of 50, and the wifi interface priority being the default of 100, it ALWAYS attempts to use the wifi ...

Just as a note, don't use WIFI_REASON_4WAY_HANDSHAKE_TIMEOUT to determine whether or not the password is correct. I made ...
