after that is still possible to load an old image (eg bh 1.6.3)
or better to wait the future bh one?

The new boot is needed to flash images up to 128Mb size.
I think you always update the bootloader of your boxes. This should not impact old images because they are smallest :)
About drivers: they will be included into new BH :)

If you upload the boot loader, you don't need to reinstall the image you are using.
However, there should not be any problem to install the BH 1.6.3.
 
duo 'brick' test passed:
new bootloader, then tested to update the duo with the present image backup (1.6.3), and all fine :thumbup:
 
a911 i think that is needed the serial connection for verify it (now i haven't the serial-usb adapter for test)

edit: df results
/dev/mtdblock2 4096 388 3708 9% /boot
should this one looks as 2048 one?
