UART0 outputs garbage when initializing I2S_0

When initializing I2S in master mode using ESP-IDF 5.0, UART0 outputs garbage and crashes (most of the times) I can't really investigate the crash, since the last few words are unreadable due to UART corruption. Since IO0, IO1 and IO3 can all be configured to be the I2S MCLK output, I have configure...

Re: ESP-IDF Heap analyzation

I've managed to get it to work.

As the dump function was called in an execution speed sensitive context, I needed to raise the UART baudrate to get it to print fast enough.

Cannot connect to ESP32 via JTAG

Hi, I'm trying to connect my development board over JTAG, but it only connects some of the times. I'm starting openocd with: openocd -s "C:\esp-idf-5.0.1\tools\openocd-esp32\v0.11.0-esp32-20221026\openocd-esp32\share\openocd\scripts" -f interface/ftdi/esp32_devkitj_v1.cfg -f board/esp-wroom-32.cfg -...

ESP-IDF Heap analyzation

Hi! I'm wanting to analyze the memory usage of my app, since I think there are a few memory leaks. The app ultimately crashes whenever enough data has been parsed. I've enabled the standalone memory analyzer, which wouldn't work as intended. Printing of the memory report took so long, that the ESP32...
