Quick update. In esp32/mptask.h there exists: #define MICROPY_TASK_PRIORITY MP_THREAD_PRIORITY #define MICROPY_TASK_STACK_SIZE (8 * 1024) #define MICROPY_TASK_STACK_SIZE_PSRAM (12 * 1024) #define MICROPY_TASK_STACK_LEN (MICROPY_TASK_STACK_SIZE / sizeof(StackType_t)) I believe this is where we could increase the stack size, but I am unsure of the sanity and practicality of this... Thoughts?
