S12VR Flash re-prog SW thru LIN

keisukeninomiya — Wed, 01 Jul 2015 00:12:03 GMT

Customer is asking if FSL can support Flash re-programming SW by LIN on S12VR.

Do you have any requirements from other region's customer about this kind of SW ?

If you already have it, please share.

Or if you know any partner who can support or already have it,
let me know. Thanks.

Regards,

Nino

HI Keisuke,

As starting point I would like to recommend application note AN4258:

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

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

This simple SCI bootloader (S12G as target) could be taken as template for porting to S12VR and LIN interface.

As simple template for LIN (according v1.3 specs), you could take attached example code. My example code was designed for S12G (based of SofTec example code) however there should not be any big differences in compare with S12VR, except missing initialization of LIN PHY interface and configure routing options (MODRR2 register),...

For LIN2.xx could be used official LIN stack:

I hope it helps you.

Have a great day,
RadekS
