Hello,

when I compare original backuped firmware with downloaded, that
there are few differences:
--------------
Filename        backup.dfu
bcdDevice       443
Firmware type   CSR-dfu2
--------------
Filename        GenericCSR.dfu
bcdDevice       ffff
Firmware type   CSR-dfu1
--------------

Can somebody explain me, what does it means and if it is not problem
for flashing?

Downloaded firmware is much longer than backuped. Is it OK?

Thanks,

Pavel Ruzicka
