Hi John, In the past, we've used the /dev/mtd* devices to write data back to NOR (spi / parallel) devices for updating firmware using something like:
dd if=newimage.bin of=/dev/mtd0 Of course, you need to have your kernel configured to have the mtd drivers loaded and you need to make these areas writable (most linux board packages set these to read-only, given the sizeable gun you have pointed at your shoes....) -Mike On Fri, Apr 30, 2010 at 2:14 PM, John Tobias <jtob...@viaas.com> wrote: > Hi, > > Does anyone successfully written the UBL image in block 1/5 from linux > userspace?
