Option Byte Flash
Erasing the option byte flash without programming it immediately afterwards will activate RDP1 level protection. Our option byte flashloader works best if RDP1 level protection stays deactivated. For this reason any explicit erase operation will be skipped by our flashloader. Instead, any necessary erase operation is implicitly executed during flash programming. It is therefore recommended to only perform programming operations on the option byte flash.
Watchdog Handling
- The device has a watchdog IWDG.
- The watchdog is fed during flash programming.
Device Specific Handling
Reset
- The device uses normal Cortex-M reset, no special handling necessary, like described here.
Limitations
Security
- Device supports readout protection (RDP). If a RDP1 level protected device is detected, the user will be prompted to unsecure the device.
