TrustZone
Flash programming with TrustZone enabled is supported (DLM state SSD and NSECSD). Whether the RAMCode is usable depends on the "Device Lifecycle Managment" state (DLM). In the NSECSD state only the RAMless flashloader can be used. This is a technical limitation. The J-Link software is not able to decide at runtime when to use the RAMCode or RAMless flashloader. If you want to use the RAMless flashloader, you have to add "_RAMLess" to the device name, e.g. use "R7FA4E10D_RAMLess" instead of "R7FA4E10D". Please note that a significantly lower programming speed has to be expected with the RAMless flashloader.
