ESP32-S2 RTC-GPIO hold is not woking after first time.

[pavlos77]

Hello, I want to blink a LED , when the ESP is in deep sleep mode ( CPU is off ) from ULP-FSM. I set the appropriate registers ( See below), i can hold the LED ON with no problem and then turn it OFF, but i cannot turn it ON again after the first time.I have read and printed the register and i can see that it set properly.Is is it a bug or i am missing something?

Turn OFF LED

I_WR_REG_BIT(RTC_CNTL_PAD_HOLD_REG, rtc_io_number_get(LED_GPIO), 0)
I_WR_REG_BIT(RTC_GPIO_OUT_W1TC_REG, (uint8_t)(RTC_GPIO_OUT_DATA_W1TC_S + rtc_io_number_get(LED_GPIO)), 1),
I_WR_REG_BIT(RTC_CNTL_PAD_HOLD_REG, rtc_io_number_get(LED_GPIO), 1),

Turn ON LED

I_WR_REG_BIT(RTC_CNTL_PAD_HOLD_REG, rtc_io_number_get(LED_GPIO), 0)
I_WR_REG_BIT(RTC_GPIO_OUT_W1TS_REG, (uint8_t)(RTC_GPIO_OUT_DATA_W1TS_S + rtc_io_number_get(LED_GPIO)), 1),
I_WR_REG_BIT(RTC_CNTL_PAD_HOLD_REG, rtc_io_number_get(LED_GPIO), 1),
