Good question ... I think the reason is that if we erase a big partition
at once on dfu start, dfu-util rans into timeout ... but may I am wrong ...
IIRC at the end of a DFU transfer DFU protocol sends a "flush" to the
device ... where we currently erase the remaining sectors ... we need
this on an ubi partition, else there may remain old used UBI sectors ...
(BTW: we need an "ubi format" command ...)
@Lukasz? Am I correct? Or could we simple erase before writting?
bye,
Heiko
