ICE AM335x CAN non-linux sample code

SDSInc Tester

Hi,

I am in need of some working sample CAN bus code for the Industrial Communication Engine AM335x. I followed some threads but they lead to use under Linux and we are going to use SYS/BIOS. I found the dcanTxRx project in the StarterWare_02_01_00_01 and have built it and have been trying to run it.

This has not even run much as the code hangs in an I2C read of the CPLD in main where it is trying to set up the MUX.

I2CMasterIntRawStatusEx Line 401

CPLDI2CRead Line 112

EVMProfileGet Line 178

DCANPinMuxSetup Line 74

dcanTxRx Main Line 144

Is there other demo code ? Am I building it wrong ? I had to re-sddress the StarterWare platform project, archive build step from evmskAM335x to evmAM335x and add dcan.c and cpid.c to the project.

Any suggestions would be helpful.

Thanks

Moving this to the Starterware forum.

Reading the schematic there doesn't appear to be a CPLD on the board. I can account for all the I2C connections on the board and there is nothing there at location I2C 0x35 where the code is trying to talk to a CPLD. So why is the dcan code calling this CPLD code ? I got the dcan.c code from the StarterWare drivers directory, is there another I should use ?

Nope got it from the platform\AM335x directory. Tried the one in Drivers and it is missing calls that dcanTxRx needs.
