JTAG-Booster for IDT 64145
/BOOTCS /DEVCS0 /DEVCS1 /DEVCS2 /DEVCS3
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 1.6 “Initialization file JTAG145.INI”.)
Default:
/BOOTCS
/NOCS
Use this option to switch all chip select signals off. This may be necessary if the
device's chip select is generated via a normal decoder instead of using the IDT
RC64145 chip select unit.
/32L /32H
The JTAG-Booster is not able to handle the interface to a dual 16bit ROM
(32bit-ROM). With this two options you can select one 16bit half of a 32bit-
ROM. The option /32L selects the low word and /32H selects the high word.
Do not specify the option /8BIT together with /32L or /32H.
/WRSETUP
By default write cycles to the Flash EPROM start with address, data and write
strobe set at the same time. With the option /WRSETUP you can force the
program to generate a setup time for address and data with respect to the write
strobe.
Examples:
JTAG145 /P BIOS.ROM /VERIFY /O=-400000
This example programs the file BIOS.ROM to the flash memory with an offset of
4 MByte to the top of the boot flash. This is the point, where the MIPS Core
fetches the first instructions.
JTAG145 /P CE.EVN /VERIFY /32L /DEVCS0
This example programs the file CE.EVN to the lower word of a 32bit-ROM
connected to DEVCS0#.
