Undefined reference to `nrfx_twim_enable' won't compile

[loganmeyer3]

I am using nrf sdk with version 17.1 and using an nrf52dk

I am unsure what exactly could be the problem.  I believe my sdk_config is setup correctly with 

• NRFX_TWIM_ENABLED - nrfx_twim - TWIM peripheral driver
• NRFX_TWI_ENABLED - nrfx_twi - TWI peripheral driver
• TWI_ENABLED - nrf_drv_twi - TWI/TWIM peripheral driver - legacy layer

all enabled with both

• TWI0_USE_EASY_DMA - Use EasyDMA (if present)
• TWI1_USE_EASY_DMA - Use EasyDMA (if present)

enabled.

I found this post post for reference and guidance.

Any help would be greatly appreciated.  Happy holidays.
