Computing of CRC value of the flash memory

[zorrotz]

Hi,

I need to test the invariable memory of a Kinetis using the functions provided by the core self-test library for Kinetis CM4 devices.

For other microcontrollers, using CodeWarrior 10.6, the CRC of the invariable memory is calculated in the linking phase and saved in the invariable memory with the application code.

How can this be done with MCUXpresso?

This article describes how to do it for S-Record files: CRC Checksum Generation with ‘SRecord’ Tools for GNU and Eclipse | MCU on Eclipse , but what about .axf ELF/Dwarf files?

Regards,

Igor Vicente

Hello Pablo,

The MCUXpresso IDE also can generate S-record files, then you can refer to the article you menetioned

to compute CRC.

About how to generate S-record files please refer to : MCUXpresso IDE: S-Record, Intel Hex and Binary Files | MCU on Eclipse 

Hope it helps

Have a great day,
TIC

Hello Alice,

Finally I have implemented the flash memory test successfully folowing the post. Know I can debug the application with the information of ELF file.

Thanks

Best regards,

Igor
