Hello,
I am developing custom audio codec driver on IMX6ULL with ESAI as interface.
My interface mapping is as below,
pinctrl_esai: esaigrp {
fsl,pins = <
MX6ULL_PAD_CSI_DATA00__ESAI_TX_HF_CLK 0x1b0b0
MX6ULL_PAD_CSI_DATA01__ESAI_RX_HF_CLK 0x1b0b0
MX6ULL_PAD_CSI_DATA04__ESAI_TX_FS 0x1b0b0
MX6ULL_PAD_CSI_DATA05__ESAI_TX_CLK 0x1b0b0
MX6ULL_PAD_CSI_DATA07__ESAI_T0 0x1b0b0
MX6ULL_PAD_CSI_HSYNC__ESAI_TX1 0x1b0b0
MX6ULL_PAD_CSI_PIXCLK__ESAI_TX2_RX3 0x1b0b0
MX6ULL_PAD_CSI_MCLK__ESAI_TX3_RX2 0x1b0b0
MX6ULL_PAD_CSI_DATA02__ESAI_RX_FS 0x1b0b0
MX6ULL_PAD_CSI_DATA03__ESAI_RX_CLK 0x1b0b0
MX6ULL_PAD_CSI_DATA06__ESAI_TX5_RX0 0x1b0b0
MX6ULL_PAD_CSI_VSYNC__ESAI_TX4_RX1 0x1b0b0
>;
};
And Codec is master and CPU (ESAI) slave.
After all coding, when I am running the aplay, i am getting write error: Input/output error.
Looks like the clock is not configured correctly.
can anyone tried this setup before? please share your implementation details.
Thanks,
Kiran
