Hello,
i am a litte bit confused about the Boot1.2 and Boot1.3
Has somebody experimented with boot 1.3 ? What are the differences? Any ideas which software to use for reverse enginering?
It seems to be possible to drive the spi Flash with 80 Mhz instead of 40 Mhz by patching the Boot 1.2. Is that correct?
Boot partition is selected by the last 3 sectors in flash (Boot1.2) 4MBit & 32 MBit OK, but there seems to be a limitation for
executable userbin1 and userbin2 to a 512KB (2*) limit. Is this correct?
I want 2048KB (2*).
Boot1.2 can be patched to override this 512KB (2*) limit,
but will the SDK flash userbins > 512KB to the correct place in memory when 32MBit Flash is installed? I think not.
Will Boot1.3 help to use Userbins 2*2048 KB with SDK cloud update?
