Hi TI,

In our project,we need to get configuration informations from Compact Flash Card by MCU's data buses,how to coding CF card drivers and port the FATFs to our application?

Hello Frank,

If the CF supports SPI mode, you can use HALCoGen to generate SPI driver as the starting point.

Hi Frank,

If it requires a special CF dedicated interface, our devices don't have this kind of interface.

The CF card interface as follow.

How to interface it with TMS320F28335?

Hello,

Reading the signals required by the CF in your schematics, I think that the EMIF doesn't meet the those requirements.

Are there a MCU which integrates the CF controller in your product series?

Hello Frank,

Hercules device don't support CF. I am not sure about C2000, MSP430, and processors. Please post your questions to C2000 and MSP430 forum.
