LAUNCHXL-F28379D: DevCfgRegs is undefined

Hi,

I am working on a project where I am trying to move CAN-A control over to CPU-2.

I have initialized the CAN GPIO and then used the following lines to transfer control over to CPU-2.

EALLOW;
DevCfgRegs.CPUSEL8.bit.CAN_A = 1; //CPU2 is the owner
//DEV_CFG_REGS.CPUSEL8.bit.CAN_A=1;
EDIS;

This is giving me build error saying "DevCfgRegs" is undefined.

I am able to see this register on the expressions window in CCS. I am not sure what else do I need to include to be able to use this register. Please guide.

Thanks

Sumeet

Hi Sumeet,

You can declare DevCfgRegs in your file.

volatile struct DEV_CFG_REGS DevCfgRegs;

Hi. Adding this line gives the error -- variable "DevCfgRegs" was declared with a never-completed type

The issue is caused by missing the necessary header file that defines the struct "DEV_CFG_REGS"

The struct "DEV_CFG_REGS" is define din F2837xD_sysctl.h

Thanks I found them in here. Alternatively I was also able to write the value directly to the address and change to CPU2.
