I2S BCLK will not output continuously without data

[Terence Kim]

The BCLK_CONT option to i2s_configure() is not being honored anywhere. How do I get BCLK to output continuously without having to do i2s_write() or i2s_read() calls over and over?

Hello,

Please correct me if I'm wrong, but is the goal to have a continuous clock output without sending any data?  The I2S_OPT_BIT_CLK_CONT option flag is not supported in our driver, as the MCK signal can only be enabled by triggering the transfer start task on our devices.

Best regards,

OK - it sounds to me then that I have no choice but to serve up buffers via i2s_read/write repeatedly to keep the MCK signal outputting. Thanks.
