Hello Everybody,

I look into the IAR Example and the Application not for a Bootloader by
an XMC4000 device

Infineon-XMC4000_TOO_Bootloader-AN-v01_03-EN.pdf
Infineon-AP32269_XMC4000_CAN_BSL-AN-v01_00-EN.pdf

If I understood correctly the XMC has no Flash regio (ROM) that I can use for a
safe bootloader as other Cortex-M4 manufacture. There I can secure the are
via fuses and update the Flash for example from USB.

Why It is not possible by the XMC µC or does anyone know a method to ´
implement a secure bootloader via USB for the XMC


best regards


EbbeSand

P.S. First I look for the mechanism to prevent the physical deletion of the bootloader,
but secondly, about the security of the firmware update itself

Hi,

The XMC4 family provides both write protection and read protection of flash contents.
