Production Flashing of S32K118 & S32K148

[Learner]

Hi Experts,

Need your support  for the following:

In my project I am using two s32k series of microcontroller. S32K118 & S32148

Sometimes, we accidently flash S32k118 elf in S32K148 and vice versa.

I am concerned how we can deal with this issue in production. Please guide. 

Please suggest/share the generic method of flashing microcontrollers in production
thanks

Hi,

this is something you have only in your hands. There is a register (read only) which describes the device you are using (see 11.3.1.8 System Device Identification Register (SDID) ......11.3.1.8.3 Diagram in the reference manual ..... 11.3.1.8.4 Fields)

You should check whether your programmer is able to read this register before programming the device and it is able to check which device should be programmed and which is really programmed.

Best regards,

Ladislav
