Hello.

I don't think you want help ...

I can tell you that when I used a 1GB SD card the firmware was updated.
The whole operation from power on took about 2 seconds.
During this time the red led blinked near the MCU.
On the SD card there was no longer my file but only the bakup file of the old firmware.
