In PlatformSupport\WARPMAC\warpmac.c, warpmac_init() initializes all of the hardware components. In particular, our interests are in the OFDM Receiver initialization (lines 677ff). Where are functions such as mimo_ofdmRx_init() defined?
Is there a particular sequence or timing required for configuring the OFDM receiver? Is the code in warpmac.c a sufficient guide?
Other than the initialization code in warpmac_init() is there any other up front initialization required for the OFDM receive registers?
Thanks,

The various calls to ofdm_TxRx_* in warpmac_init() handle all the up-front initialization of the PHY.
I'll be the first to admit it's not particularly clean at the moment. We're actually re-working WARPMAC and the OFDM TxRx drivers to make it easier to use (and maintain). The code-in-progress is already in the repository, and the new API documentation is coming together. We plan to post an updated reference design using the new code in the next few weeks.
