I have experience developing 8051 but I'm very new to ARM comparing t AVR.

My question is how ARM save data since it doesn't have built in eepro like AVR? I checked many ARM eval board but they all don't have externa eeprom.

I found a ARM board that completely suit my needs but it doesn't hav eeprom. I would think this is normal to every ARM and am I missing something?

thanks for any help.

Some ARMs with on-chip flash are self-programming. You can use a spare flash sector to store your nonvolatile data. Otherwise, add an I2C or SPI EEPROM.

You add an EEPROM or flash or MRAM or some other form of non-volatile storage.

Don't they have flash either?

Probably.
