ota_basic example can receive new image via TCP. However - writing to flash with interrupts disabled causes data loss, and the TCP flow is very slow to recover. Linux sender quickly ramps up RTT timer to very long retry intervals, crippling performance & throughput. Running the update without the flash writes causes the data to be received quickly, so this is definitely an issue with the time taken for the erase cycle. Progress towards #10
