during LC in cust_del, if i modified the flash and reset the mcu, hse smr check maybe stop the app code run due to che check failed? how to recover the mcu, for example ,clear the SMR/CR record when app code not run? is there any best practice workflow for debug secure boot ?
I don't understand this question.
During CUST_DEL, APP Debug port is open, No restriction for Application development, HSE Debug Port Closed
Could you describe your question a bit clearer? Thanks
