Can I Flash other controller using S32K144

[raviranjankumar]

Hi,

I am working on S32K144 EVB, I want to flash other microcontroller using S32K144 through SWD. Is it possible, if it is possible then, please help me with procedure.

Thanks and Regard

Hello

It is possible to use the free Keil MDK evaluation version (MDK Lite) to program any size of Flash.  While MDK Lite limits compilation and debugging to 32K, there is no such limit for Flash programming.  You should be able to program any ELF-DWARF file (GCC is) and maybe a hex file.

Keil supports both OpenSDA in both P&E and CMSIS-DAP modes.  CMSIS-DAP firmware is located here: www.keil.com/appnotes/docs/apnt_299.asp

See µVision User's Guide: Flash Programming 

You might look at LPC-Link V2 - this is also CMSIS-DAP compliant.

Hello Ravi,

S32K144 EVB uses SWD to flash/debug S32K MCU, it should be no problem to flash another MCU that supports SWD as long as connection with main MCU is removed.

Here is a post that shows how to use FRDM boards (Kinetis) as SWD programmer/debugger and this same principle should apply, due SWD circuit is the same in both boards.

Hope this helps!
