CPLD profile on AM335x, Is there a documentation?

Laurent Z

Hello,

I'm working on a product that need to have wifi and Dcan. I'm using AM335x evm to develop the application. I do understand that the wifi work on profile #0 and Dcan on profile #1. However I downloaded the CPLD pins allocation from this websit:

http://processors.wiki.ti.com/index.php/AM335x_General_Purpose_EVM_HW_User_Guide#Pin_Use_Description

and I see the same names and functions assigned to the same pins on both profile #0 and #1. Therefore, why the Dcan doesn't work on profile #0.

The same for the haptics function that work only on profile #4 but I can see GP(Haptics) assigned on profile #3 (lcd_pclk), on profile #0, #1, #2 (gpmc_a4), etc...

I'm a bit confused, can someone explain to me how it works?

Thank you very much

The profiles are separate operational modes. I think this is a mistake in that Pin Use Description. The DCAN is only enabled on those pins in profiles 1 & 2. We'll work to get that the document updated.

COM board is the WiFi communication board that is plugged in the COM connector. You may or may not have it on your kit.
