I have a bootloader and application system design.
The bootloader protect the flash against extern manipulations with "XMC_FLASH_PROTECTION_READ_GLOBAL"
When the bootloader update my application, do i have to unlock the flash with XMC_FLASH_VerifyReadProtection ?
Thanks,
Embedded

Hi,
Yes, this should temporarily disable the flash write protection.

Hi,
No, the debugger will not have access after a successful call to XMC_FLASH_VerifyReadProtection() with the correct password.
Yes, the read protection also enables the write protection.
