4. Flash API “__api_wr_code_page” with 0 Data in Length Parameter Field
When the Flash API “__api_wr_code_page” is called with the field nb_data equals 0 then 255 data are written in Flash.
Workaround
Test the bootloader to check the size of the value nb_data.
If nb_data = 0 returns in the application without launching a programing sequence, or check in the Flash API.
