Porting DCAN module from RTOS to HLOS

Vijay Krishnan

Hello Friends,

I am trying to port DCAN module from RTOS to HLOS.I am facing difficulties in including xdc related headers in hlos.I request you to let me know how to make the build in linux know the packages related to xdc.

I am getting the following errors related to xdc.I expect many more related to xdc.

utils_dcan.c:84:84: fatal error: ti_components/os_tools/linux/xdctools_3_32_01_22_core/packages/xdc/std.h: No such file or directory

compilation terminated.

In file included from system_dcan.c:75:0:

utils_dcan.h:98:21: fatal error: xdc/std.h: No such file or directory

Best Regards,

Vijay

Hi Vijay,

You cannot port DCAN from RTOS to HLOS this way. Can you check if linux has support for DCAN.

Hello Rishabh,
I would like to do receive the CAN frames,do acceptance filtering,store it in the message objects(RAM) and unpack the frames and do a lot of post processing. I would like I would like to write a utility like util_dcan.c in hlos .Please give your views and suggestions on how to compile my changes in hlos.

Best Regards,
Vijay

HI
DCAN driver is included in the LInux package - you can refer to processors.wiki.ti.com/.../Linux_Core_DCAN_User's_Guide
for more instructions on the usage.

You will also need to get familiar with general CAN usage on linux - you will find lot of useful resources on the web, you can start with https://elinux.org/CAN_Bus
