- For Production programming
- For application code update or customization in warehouse
- For repairing or update in the field
3.4 Backup Boot Flash method
SF600 / SF600Plus can also be used together with DediProg backup boot flash modules so
that it forces the application to boot from the backup flash located in the backup boot
flash module instead of the soldered SPI flash on the application which it is disabled. The
backup serial flash can then be accessed at any time by the SF600 / SF600Plus without
any possible conflict with the application controller. In this case, SF600 / SF600Plus
cannot update directly the on board Serial Flash to avoid conflict with the controller.
Applications:
A. Development purpose as the system can boot from the backup Flash for the code
trials. Engineer can update safely the backup Flash with new code and without any
conflict risk with the application controller.
B. Repair purpose as the system can still boot from a backup memory even if the on
board Serial flash is corrupted. The technician can use the application flash update
tools after the boot to update the on board Serial flash.
Remark: Pin header adapter need to be used
