IO8 did not maintain the previous level state after entering deep sleep (IDFGH-5738)

[zarockfat]

Environment

• Module or chip used: ESP32-C3
• IDF version : v4.4-dev-1254-g639e7ad49
• Build System: idf.py
• Compiler version : xtensa-esp32-elf-gcc (crosstool-NG esp-2020r3) 8.4.0
• Operating System: Linux
• Using an IDE?: No
• Power Supply: external 3.3V

Problem Description

Expected Behavior

I want to keep the previous pin level state after IO8 enters deep sleep

Actual Behavior

After entering deep sleep, IO8 did not maintain the previous low level state, but changed to the high level state

Steps to reproduce

1. before entering deep sleep, I output IO8 to low level
2. and then call gpio_hold_en(), gpio_deep_sleep_hold_en(), esp_deep_sleep_start( )
3. After entering deep sleep, IO8 did not maintain the previous low level state, but changed to the high level state

#define TEST_GOIO  GPIO_NUM_8

		.pull_up_en = GPIO_PULLUP_DISABLE,
	};	
		
	ESP_ERROR_CHECK(gpio_config(&config));
	ESP_ERROR_CHECK(gpio_set_level(TEST_GOIO, 0));

	ESP_LOGI(TAG, "Measure the pin voltage here ===Line:%d \ n", __LINE__);
	vTaskDelay(2000 / portTICK_RATE_MS);
	ESP_LOGI(TAG, "Measure the pin voltage here ===Line:%d \n", __LINE__);

	ESP_ERROR_CHECK(gpio_hold_en(TEST_GOIO));	
	gpio_deep_sleep_hold_en();
	

	esp_deep_sleep_start();
