NRFX_CHECK Macro for I2S Driver

[Krunal Desai]

Hi there,

I have a project where I am using the NRFX I2S Driver. I am using SDK 15.3.0 and SES 14.2.

In my sdk_config.h, I have the legacy I2S driver disabled and the NRFX I2S driver enabled (NRFX_I2S_ENABLED set to 1). However, in SES, nrfx_i2s.c shows as entirely greyed out after the NRFX_CHECK(NRFX_I2S_ENABLED) macro. As a result, it doesn't get compiled in and I have unresolved symbols.

If I manually comment out the pre-processor checks in nrfx_i2s.c, everything works fine. Obviously, I do not want to directly be modifying SDK source code.

Any ideas?

Hi Kenneth —

Perfect, that did it; removed all I2S_* entries from sdk_config.h and it is building successfully. Had to clean the solution a few times to get it to work, but then it was good to go.
