The spi_device pointer you have is stored in memory somewhere. There's likely some buffer located at a lower address in memory that overflows, overwriting the spi_device pointer. Check where your spi_device pointer is declared in your code, then see if there's a variable declared before that that m...

Potentially a buffer overflow in the variable 'above' it.

I initialize the spi as follows static esp_err_t spi_master_init(void) { esp_err_t ret; spi_bus_config_t buscfg = { .miso_io_num = PIN_NUM_MISO, .mosi_io_num = PIN_NU...

I am not sure but if somebody configures the tool.json file to point the latest version of open ocd the problem will be solved after
running the install.bat in esp-idf directory.
Am I right?
