But with this restriction, it is not possible to use flash devices with a block size other than 64kB in combination with alternative SBL address ot firmware start addresses, which are not a multiple of 0x4_0000)[/quote] Hi Jo, I do not understand this properly, the property of NOR flash is that writes are supported at block level only, so as long as you enter the correct block size thr flash write would work.
