s32K144 freemaster sw mode can not work

[jiangbolwj]

i see  #define FMSTR_DISABLE 0 /* To disable all FreeMASTER functionalities */
#define FMSTR_USE_LPUART 1 /* To select LPUART communication interface */
#define FMSTR_USE_FLEXCAN 0 /* To select FlexCAN communication interface */
#define FMSTR_USE_PDBDM 0 /* To select Packet Driven BDM communication interface (optional) */

fmstr support uart,can,bdm.it not support sw?

Hello, 

I'm not sure if i understood correctly your question. I think you are referring to the communication protocols supported by FreeMASTER, correct ?

If that is the case, then you will find all the protocol supported here: https://community.nxp.com/docs/DOC-334485 page#2

Hope this helps!

Daniel

Hello,

First off all, let us try to clarify a few things:

#1:  FreeMASTER supports direct communication over JTAG (without any other stack/driver/overhead) only for 56F8xxx. For any other targets, the communication with the host is done via BDM/EOnCE plugins. Basically, your target application (S32K144 in this case) must be linked with the Serial Driver that needs to run on your target.

 

#2: You need an external debug probe that supports the JTAG/BDM protocol like a P&E Multilink.

Are you fine with these constraints ?

Hope these clarify your concerns!

Best regards,

Daniel
