/LENGTH=hhhhhh
The number of programmed bytes may be limited to LENGTH. If no LENGTH is
specified the whole file is programmed.
Default:
Abbreviation:
/NODUMP
In case of a verify error the contents of the flash memory is written to a file with
the extension .DMP. With /NODUMP you can suppress this feature.
/ERASEALL
Erase the whole flash device. If this option isn't set, only those blocks are erased
where new data should be written to.
/NOERASE
This option prevents the flash device from being erased.
/ROMCS0 /ROMCS1
This options may be used to specify one or more chip select signals to the flash
memory. The used chip selects must be defined as output and inactive in the
initialization file. (See chapter 1.8 “Initialization file JTAGEL4.INI”.)
Default:
/NOCS
Use this option to switch off all chip select signals. This may be necessary if the
device's chip select is generated via a normal decoder instead of using the AMD
ÉlanSC400/ÉlanSC410 chip select unit.
/NOWRSETUP
By default write cycles to the Flash EPROM are realized with three steps: 1. set
address/data 2. write strobe active 3. write strobe inactive. In most cases it is
possible to set the write strobe coincident with setting of address and data by
specifying the option /NOWRSETUP. This increases the programming speed
by 50%.
