我在搭建一个基于MC9S12XS128芯片CAN Bootloader的程序，但是缺少S12MSCAN头文件，据说，这个文件可以在CodeWarrior安装目录下找到，但是我没找到。希望有这个文件的人能分享给我，谢谢你！

Hi Li,

Could you please specify which software resource you used as your reference?

I didn’t found any note about S12MSCAN.h file in application note AN3391 LFAE Bootloader Example and Interface for use with AN2546

http://www.nxp.com/files/microcontrollers/doc/app_note/AN3391.pdf

http://www.nxp.com/files/microcontrollers/doc/app_note/AN3391SW.zip

and also, no information about S12MSCAN.h file in MSCAN driver:

http://www.nxp.com/files/microcontrollers/software/device_drivers/MSCAN_S12_DEVD.zip

I hope it helps you.

Have a great day,
Radek

Hi Radek,

      Thank you so much. I have deal with it.

      Did you build any project about CAN Bootloader used for MC9S12XS ? Could you give me an example or program resources ？

Hi Li,

Personally, I never build a bootloader for S12XS, however you may relatively simply use bootloaders examples for S12XE.

The S12XS and S12XE families are highly compatible. The XS family has a reduced peripheral set from the XE family.

More details about differences between S12XE and S12XS families are described in AN3327 Using the S12XE-Family as a Development Platform for the S12XS-Family

http://www.nxp.com/files/microcontrollers/doc/app_note/AN3327.pdf

The CAN bootloader for S12XE is described in AN3391 (links are in my previous reply).

If you look for some simpler bootloader, I would like to recommend also AN4258 Serial Bootloader for S12(X) Microcontrollers Based on 180 nm Technology

http://www.nxp.com/files/microcontrollers/doc/app_note/AN4258.pdf

http://www.nxp.com/files/microcontrollers/doc/app_note/AN4258SW.zip

Unfortunately, this bootloader implement by default only SCI interface. The CAN bus must be implemented additionally.

Some simple CAN examples may be found for example at:

https://community.nxp.com/docs/DOC-95116

or https://community.nxp.com/docs/DOC-329209

I hope it helps you.

Have a great day,
Radek
