I try to add an Individual reset of ESAI Transmit function by suggestion of following community thread.
I'm adding a reset sequence of "18.104.22.168 Initializing the ESAI Transmitter Section"
in ReferenceManual_iMX6DQPRM_rev2 to SNDRV_PCM_TRIGGER_SUSPEND,
SNDRV_PCM_TRIGGER_STOP and SNDRV_PCM_TRIGGER_PAUSE_PUSH command response code on
After audio playback by aplay and gst-play-1.0 command, ESAI_TX_FS and ESAI_TX_CLK signal state
both High and Low level randomly.
By changing the PAD control register value of "MX6QDL_PAD_ENET_CRS_DV__ESAI_TX_CLK" and
"MX6QDL_PAD_ENET_RXD1__ESAI_TX_FS" from 0x0001b030 to 0x00013030 in "imx6qdl-sabreauto.dtsi"
Initial signal revel both ESAI_TX_FS and ESAI_TC_CLK, it will change from High to Low by Pull-down register
But after audio playback, it will change High or low level randomly.
Attached file is a source code I modified.
Do I need some more modify or some mistake in it?
Do you mind explaining this in more detail?
