|
If "n" - No virtual mode. All eFuse operations are real and use eFuse registers.
|
|
If "y" - The virtual mode is enabled and all eFuse operations (read and write) are redirected
|
|
to RAM instead of eFuse registers, all permanent changes (via eFuse) are disabled.
|
|
Log output will state changes that would be applied, but they will not be.
|
|
|
|
If it is "y", then SECURE_FLASH_ENCRYPTION_MODE_RELEASE cannot be used.
|
|
Because the EFUSE VIRT mode is for testing only.
|
|
|
|
During startup, the eFuses are copied into RAM. This mode is useful for fast tests.

|
|
In addition to the "Simulate eFuse operations in RAM" option, this option just adds
|
|
a feature to keep eFuses after reboots in flash memory. To use this mode the partition_table
|
|
should have the `efuse` partition. partition.csv: "efuse_em, data, efuse, , 0x2000,"
|
|
|
|
During startup, the eFuses are copied from flash or,
|
|
in case if flash is empty, from real eFuse to RAM and then update flash.
|
|
This mode is useful when need to keep changes after reboot
|
|
(testing secure_boot and flash_encryption).
