K82: SB key programming

EugeneHiihtaja — Tue, 02 Apr 2019 12:42:33 GMT

Hello !

I'm not able to find FlashProgramOnce in latest SDK 2.5.x.

8.6 SB File Decryption Support

The SB key
begins at offset 0x30 in the program once registers.
For example, to program a key of 000102030405060708090A0B0C0D0E0F:
• FlashProgramOnce to index 0x30 with 4 bytes of 0x03020100
• FlashProgramOnce to index 0x31 with 4 bytes of 0x07060504
• FlashProgramOnce to index 0x32 with 4 bytes of 0x0B0A0908
• FlashProgramOnce to index 0x33 with 4 bytes of 0x0F0E0D0C

What is current equivalent of this function what can be used for write SB key to K82 MCU and SDK 2.5x ?

Regards,

Eugene

Hi Eugene,

Please check FTFx_CMD_ProgramOnce() function located in fsl_ftfx_controller.c driver.

Hope it helps!

Have a great day,
Felipe
