Well, if your programming tools can write to EEPROM, then you could describe the section in the linker script, and then direct const data there.

Alternatively your code could determine it's on a blank device and write a block of default data out there. If the data is device specific (serial number, calibration, configuration), etc your code could enter a test mode allowing you to send/write data to EEPROM during production/final testing.

I use stlinkv2 and openocd with eclipse. Probably openocd  doesn't support program this eeprom.

I guess

I will have to

keep

a copy of the

data from the

EEPROM

in

flash

and

to program

it

after the start
