How can i upgrade with sd card. I was try 5 time and i cant upgrade braiins os. Give me sd card download link.
I don't know what are you trying to do. If its installed into NAND, you can simply upgrade by refreshing packages and installing firmware.
I haven't tried, but if you are running from SD, the same thing could work, not sure if there is enough space. Else simply download the newer image and reflash the sd card.
As shown in the official documentation page, images are always at
