following code is OK with emblocg gcc GUI

MEMORY { FLASH (rx) : ORIGIN = 0x0003B000, LENGTH = 0x4C00 RAM (rwx) : ORIGIN = 0x20002400, LENGTH = 0x1C00 UICR (r) : ORIGIN = 0x10001000, LENGTH = 0x00fc }

SECTIONS { /* Section for boot loader sections in managed flash*/ .nvram (0x0003FC00) (NOLOAD): { KEEP((.bootloaderSettings)) } / Sections for UICR assignment from loaded data. / .uicrBootStartAddress (0x10001014): { KEEP ((.uicrBootStartAddress)) } > UICR ...

FYI, this fragment in my linker script did the trick.

UICR (r) : ORIGIN = 0x10001000, LENGTH = 0x00fc

}

SECTIONS { /* Section for boot loader sections in managed flash. / .nvram (0x0003FC00) (NOLOAD): { KEEP((.bootloaderSettings)) }

/* Sections for UICR assignment from loaded data. / .uicrBootStartAddress (0x10001014): { KEEP ((.uicrBootStartAddress)) } > UICR

Where did you find a bintuils linker script to set the addresses of uicrbootstartaddress and the bootloader settings?

Also, the version of the gcc_util file that I have already includes the following. Did this not work for you?

attribute ((section(".uicrBootStartAddress"))) uint32_t m_uicr_bootloader_start_address = BOOTLOADER_REGION_START;
