SW-EK-TM4C1294XL: boot_loader example project using CAN can't find CAN_TX_PIN_PCTL define

Chris Simpson88

Hello

I am working with the boot loader example project and have it working with the serial UART correctly. When I change the project to use CAN in the bl_config.h and recompile the project I get the errors

Description Resource Path Location Type
#20 identifier "CAN_RX_PIN_PCTL" is undefined bl_can.c /boot_serial/boot_loader line 1398 C/C++ Problem

Description Resource Path Location Type
#20 identifier "CAN_TX_PIN_PCTL" is undefined bl_can.c /boot_serial/boot_loader line 1398 C/C++ Problem

I cant find these defines anywhere.

Thanks

Let it be noted that the (referenced) post applies to "4C123." It may - or may not - prove proper for poster's "4C1294."

This leads to a "more general" & possibly "more valuable & interesting" issue - in general - are the GPIO Pin Control "Set-Ups/Configs" generally SHARED between "4C123 & 4C129?"

Looks like on the 4C123 its

#define CAN_RX_PIN_PCTL 8
#define CAN_TX_PIN_PCTL 8

and on the 4C129 its

#define CAN_RX_PIN_PCTL 7
#define CAN_TX_PIN_PCTL 7

Hi Bob

Thank for your help I now have the compile working for the boot loader with CAN. I will be testing ASAP.
I am just wondering why these defines are missing from the generated bl_config.h in the sample boot_loader project.
I found the issues exists with both the 4C123 and the 4C129 boot_loader sample projects.

Thanks
