pcnt unit 6 and 7

[diarus]

Hello. Please help me. I'm need to use esp32 counter unit 7 in my project. Why do fastaccelstepper and counter work correctly only when using DRIVER_RT? Does the esp32 reboot in other modes? The description indicates that the 6th and 7th units of the counter are free.
There are 2 motors in the project.
When starting the project, the code causes the esp32 to reboot:
`
Setup ()
.......
stepperval = engine.stepperConnectToPin(stepPinStepper_V);
steppergorizont = engine.stepperConnectToPin(stepPinStepper_G);

pcnt_config_t pcntConf = { };
pcntConf.unit = PCNT_UNIT_7;
pcntConf.pulse_gpio_num = metr_count;
pcntConf.pos_mode = PCNT_COUNT_INC;
pcntConf.counter_h_lim = 10;
pcnt_unit_config(&pcntConf);
pcnt_counter_pause(PCNT_UNIT_7);
pcnt_counter_clear(PCNT_UNIT_7);
pcnt_set_filter_value(PCNT_UNIT_7, 1023);
pcnt_filter_enable(PCNT_UNIT_7);
pcnt_event_enable(PCNT_UNIT_7, PCNT_EVT_H_LIM);
pcnt_isr_register(summator, NULL, 0, NULL);
pcnt_intr_enable(PCNT_UNIT_7);
pcnt_counter_resume(PCNT_UNIT_7);
void loop()...
`

please try pcnt_isr_handler_add() instead of

pcnt_isr_register(summator, NULL, 0, NULL);
pcnt_intr_enable(PCNT_UNIT_7);

Thank you for your help. It is very necessary for beginners.
UINT_7 count, fastaccelstepper is working correctly. But, a new problem has appeared: TG0WDT_SYS_RESET. See the code.
TG0WDT_SYS_RESET is the reason for resetting the digital timer core of group 0 (UNIT_0 ?) in Arduino ESP32-this is the result of an Internet search for an answer.
What can help me?

seems there is a missing watchdog reset somewhere in the code. something like esp_task_wdt_reset();.

see for reference the watchdog reset in FastAccelStepper:

FastAccelStepper/src/StepperISR_esp32.cpp

Line 107 in 27df201

void StepperTask(void *parameter) {

as I have no clue, which espidf is in use on your side, one possibility is to remove the #if/#endif in your local copy of FastAccelStepper.

It could be to anywhere else in the app, outside of FastAccelStepper.

Espidf ver 4.4.7? The problem remains. See screenshot.

Does the reset happen with any of the examples e.g. UsageExample ?
