Erase of SPI flash during Bootwizard application
Quote:
In my project I want to save some user data into the last section of SPI flash, this SPI flash contain in the first section the firmware.
When I upgrade the firmware, Bootwizard erase the entire SPI flash or erase only the necessary sections ?
Can I reserve the last section (my user data) from erase ?
The Bootwizard erase only the needed sections to flash the new image. That means, the Bootwizard does not erase the complete flash.
You only have to take care in which section you will put your user data's.
Take care , that the boot image is not so big to erase your user data's and the same for the opposite.

Hi,
the Bootwizard erase in sector steps.
And does not support the write protection code.
