I2S0 和 I2S1 使用同一个管脚 for mclk. 出现编译错误。

大家好,
#define FUNC_I2S_EN (1)
#define GPIO_I2S_LRCK (GPIO_NUM_26)
#define GPIO_I2S_MCLK (GPIO_NUM_0)
#define GPIO_I2S_SCLK (GPIO_NUM_27)
#define GPIO_I2S_SDIN (GPIO_NUM_36)
#define GPIO_I2S_DOUT (GPIO_NUM_NC)

/**

*/
#define FUNC_I2S0_EN (1)
#define GPIO_I2S0_LRCK (GPIO_NUM_22)
#define GPIO_I2S0_MCLK (GPIO_NUM_0)
#define GPIO_I2S0_SCLK (GPIO_NUM_25)
#define GPIO_I2S0_SDIN (GPIO_NUM_NC)
#define GPIO_I2S0_DOUT (GPIO_NUM_13)

I2S0 和I2S1 使用同一管脚作为MCLK. 在编译时,出现错误。

E (342) esp_clock_output: esp_clock_output_start(188): Selected io is already mapped by another signal
E (342) i2s_common: i2s_check_set_mclk(755): mclk configure failed
E (352) i2s_std: i2s_std_set_gpio(162): mclk config failed
E (362) i2s_std: i2s_channel_init_std_mode(225): initialize channel failed while setting gpio pins
E (372) i2s_common: i2s_channel_enable(995): the channel has already enabled or not initialized
我使用的是Espressif-IDE。
谢谢任何的帮助。
