I am working for bootloader using S32R274 controller,I need to add secure boot functionality using CSE module.
As i read there is updation of M1,M2..and so on.
But i just need to add only BOOT_MAC_KEY ,so that BOOT_MAC will be added after secure boot process .
Can anyone tell me how to update BOOT_MAC_KEY to secure flash memory.
the BOOT_MAC_KEY can be updated in the same way as other keys using Load Key command. The sequence including sample code is described in Appendix A in the application note.
