It's not gone:

Same issue here with the ulp_adc example. The module just refuses to wake up.

It would be nice if we could do these things as easily:

Hardware accelerated graphics (like STM32 for example)

My guess would be the esp32 version of the esp8285. The blue thing looks like a memory chip. Let's hope it is 4MB (probably not).

In components/driver/include/driver/rmt.h I see this line: Is 65.535 the upper limit of the idle threshold?

Edit: after taking a better look at the code and the actual error, I think the problem is with this line inside test_my_uart uint8_t* data = (uint8_t*) malloc(BUF_SIZE); You are using malloc() without a free() when done. Try to test if allocating memory actually succeeds. (if data == null -> out off...

I am currently using just the 'default' ms-vscode.cpptools. Maybe I just don't know what I am missing out on since my previous c experience is limited to the Arduino IDE.

Oke, I adjusted the esp32.cfg file and OpenOCD is happy now. Using the Pi-Zero as an RNDIS/Ethernet Gadget, I can now run debug commands from Visual Studio Code on my W10 laptop. Thanks for the help!

I changed the '__CLANG__' code in rtos_freertos_stackings.c to get it to compile with GCC. Unfortunately, after compilation I am running into the same problem as bbx10node in the original topic . The output is 100% consistent after several tries. Open On-Chip Debugger 0.10.0-dev-g90071eb-dirty (2017...
