hello every one
i want to design stm board which  should has device firmware upgrade
but in this case i have no access to boots pins
my upgrade data will be send by 3g (GSM module) to board and 3g module just have serial communication (usart) to micro controller
 i can store upgrade data on eeprom or spi flash  and after the receive has been completed ,  use for upgrade the device
what is the best solution? 
can i use High-density devices ?
or i should use Connectivity line devices and DFU ?
