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

 

[isteric2005]

the new boot and new drivers will be integrated in the new release BH?

 

[@MujaG@]

Works fine here with latest images.

the new boot and new drivers will be integrated in the new release BH?

You will need to upgrade the boot loader before to install the next BH.

The last drivers will be integrated into the next BH.

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.

It takes less than 2 mins to shut down, update and reboot.

It took about 1 minutes....!
How do I know, the boot loader is updated?

 

[tobler]

duo 'brick' test passed:
new bootloader, then tested to update the duo with the present image backup (1.6.3), and all fine

 

[tobler]

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?

 

[isteric2005]

"cat" is comand (no cat/) , /proc/mtc is directory and file
cat /proc/mtd

if you want :
cd /proc
cat mtd
