load SBKEK with application ?

[slou26]

Hello, Today in ISP mode we use the rom bootloader key provisionning command ( blhost -p com6 -- key-provisioning set_user_key 3 sbkek.bin ) to load the sbkek into the keystore , and it's works fine . But in the future, this operation will not be possible because of Isp disabled , so we have to do this operation with an application , is it possible ? Can I use the FFR_KeystoreWrite function and how ? Thanks for your help . Regards,

Hello Sebastien,

First of all, please accept my apologies for my late reply. We have been under a big workload. Could you please clarify the MCU you are working on?

Typically,  FFR_KeystoreWrite are IAP functions so you do not have to worry if you disable ISP on your MCU. In Application Programming allows application software for programming and reading the flash memory in addition to other functions.

Best regards,

Felipe
