I am also interested in running unit tests on a host machine (via GitLab CI). Ideally, it would automatically use the same unit tests that I have written for my components in /components/mycmp/test/test_mycmp.c, just like the Unit Test App does . And if some tests are not appropriate for running on ...

Not sure if relevant or helpful, but I previously found that JTAG was unusable when the EMAC is enabled, even though they don't share any pins. I never figured out why, but configured my project with macros to disable EMAC when I need to debug with JTAG.

My guess is that the pin is initialized to Hi-Z (floating) at power-on-reset. Then it takes some time for the CPU to start running your code and set the level high.
You could try adding an external pull-up resistor to 3.3V so it goes high when the pin is hi-Z / floating.

Yep! And some ESP32 variants also have PSRAM / SPI RAM inside the same chip package.

If you can recover after reflashing the code, then it is NOT the same issue as covered in this thread/topic.
You should start a new topic.

Whoa! adding --ccache makes a huge difference. Wonder why that isn't the default?
Thanks for the tips.

The way I've dealt with this limitation is to set the HTTP header "Connection: close\r\n". That tells the client to close every connection as soon as it is finished being used. This has allowed me to serve static content and some APIs to several browsers and keep several websockets alive at once. I'...

Thanks ESP_ondrej for your confirmation that this could work.

I already have a method to detect the HW version at run-time (on our production-line, we write a hardware version code to a special NVS partition).

I have this scenario: We have existing products in the field that we continue to support with OTA FW updates. And we want to develop the next generation product which uses some different components. We would like to distribute a single FW binary that can support both old and new hardware. Specifical...

If you want a read-only filesystem that is compiled into your firmware binary, I use EspFs (a.k.a. FrogFs) and it is fast and easy to use.
