Did EK-LM4F120XL have any bootloader example code?

Hello,

 I see that the EK-LM4F120XL examples (release 9453) don't include the bootloader examples, and I need a CAN bootloader example.

Where should I find it ? 

Thanks,

Weiting

    Hello Weiting,

    The rdk-bdc and rdk-bldc kits had CAN bootloader examples written for them.  You can use those as a starting point and port them to the chipset that you're using.

    I've attached the project.  The CAN module is the same between LM3S, LM4F, and TM4C so porting should be fairly straight-forward.

    Hello,

    I used the attached file and changed the bl_config.h to become CAN bootloader.

    I change the GPIO assignment (Rx: PB4 ,Tx : PB5 ,CRYSTAL_FREQ: 8 M),I port the image to LM3s2276 , it can work.

    I change the GPIO assignment (Rx: PE4 ,Tx : PE5 ,CRYSTAL_FREQ: 16 M) ,  I port the image to EK-LM4F120XL , it can not work.

    Is my setiing wrong?

    5076.bl_config.h

    Thanks,
