Part Number: TMS320F28379D
Other Parts Discussed in Thread: C2000WARE

Tool/software: Code Composer Studio

Hi all community,

I am working on a project. So,

I wanna develop a flash kernel code on f28379d using CAN peripheral.

1.) bWhat should be my steps ? How should I start to develop it ?

2.) I looked the sci flash kernel and DCAN boot examples on C2000Ware. I kept the main logic and needed main functions (GetWordData, Init etc.). But they are developed on other MCU. Can I port them to f28379d ? If its possible, how can I do that ?

3.) After developing flash kernel code using CAN peripheral, I wanna put into flash. Is there any example to do this operation ? After that I wanna run an application code using this flash kernel code. Is there any example to do this ?

Thanks for all !

Regards.

Hello

The C2000Ware examples under /device_support/f2837xd and /driverlib/f2837xd work for the F28379D. Additionally, any of the "flash" build configurations of the examples can show you how to put a program in flash versus RAM.
There is a CAN kernel example for F2806x, although the CAN IP is different.

The CAN bootloader code can be used as part of your kernel, look under /libraries/boot_rom

Here are some discussions on creating a CAN kernel:
e2e.ti.com/.../706557
e2e.ti.com/.../708214

We have flash programmers that work with the SCI kernels, this doc can help you have a better understanding of the kernel usage process. http://www.ti.com/lit/sprabv4

hi Chris,
1.) I looked DCAN_Boot under boot_rom. There is a function which is named GetWordData. With this function, can I take any message directly ?
2.) In CAN kernel example for f2806x, there are just CAN_Boot.c and main.c sources additionally other sources are common. But in sci kernel example for f28379d, there are too many functions in sci_Getfunction source file. Which one is correct for me ? Should I port all functions which in sci_GetFunction to CAN ?

Thanks all !
Regards.

Hello

1. Yes, that is setup to receive any message setup to properly communication with message object 1 setup in DCAN_Boot_Init()
2. The F283879D SCI kernel supports multiple commands (refer to SCI_GetFunction()). The F2806x CAN kernel essentially only supports the DFU command. It is up to your design to what you need. If you just want DFU, then you don't have to implement them all, just like F2806x kernel.

Best regards
Chris
