Hi Tony,
As per K2H schematic, DAC8550 is interfaced to generate 122.88MHz clock with CDCM6208. The 122.88MHz is used for AIF2 interface. Please refer and explore AIF2 example projects to configure the SPI.
AIF2 Clock: http://e2e.ti.com/support/dsp/c6000_multi-core_dsps/f/639/p/354355/1243482.aspx#1243482
Please find the SPI configuration source from PDK installation path.
PDK Driver Utils: ..\ti\pdk_keystone2_3_00_04_18\packages\ti\drv\aif2\test\utils
Refer scbpfpga_spi.c and cslUtils.c
Thank you.
Hi Tony,
TCI6636K2H device only support the antena interface(AIF2). This device is not supported on the E2E forum. Please contact your local FAE.
