SPI: QSPI failed (IDFGH-3763)

Environment

Development Kit: ESP32-PICO-Kit
Kit version (for WroverKit/PicoKit/DevKitC): v4
Module or chip used: ESP32-PICO-D4

Power Supply: USB

Problem Description

QSPI address is sent as standard (1-bit) SPI when there is no data to send. I am using address as command to achieve QSPI for command. I am using workaround in code now - if there is no data, do not send address ( .address_bits = 0) and use data ( .tx_buffer) as pointer to command and set transfer size (.length) to 8bit.

Expected Behavior

Send address as QSPI.

Actual Behavior

Without data standard SPI is used.

Steps to reproduce

Code to reproduce this issue

code snippet:

uint8_t test_data[] = { 0x55, 0xaa };

spi_transaction_ext_t qspi_ok = {
    .base = {
        .tx_buffer = test_data,
        .length = sizeof(test_data) * 8,
        .addr = 0x81,
        .flags = SPI_TRANS_MODE_QIO | SPI_TRANS_MODE_DIOQIO_ADDR | SPI_TRANS_VARIABLE_ADDR
    },
    .address_bits = 8
};

spi_transaction_ext_t qspi_failed = {
    .base = {
        .addr = 0x81,
        .flags = SPI_TRANS_MODE_QIO | SPI_TRANS_MODE_DIOQIO_ADDR | SPI_TRANS_VARIABLE_ADDR
    },
    .address_bits = 8
};

...
    ESP_ERROR_CHECK(spi_device_acquire_bus(spi, portMAX_DELAY));
    while (1) {
        ESP_ERROR_CHECK(spi_device_polling_transmit(spi, (spi_transaction_t *)&qspi_ok)); 
        ESP_ERROR_CHECK(spi_device_polling_transmit(spi, (spi_transaction_t *)&qspi_failed)); 
        vTaskDelay(100 / portTICK_RATE_MS);
    }
    spi_device_release_bus(spi);
