JTAG-Booster for Intel XScale
JTAG_XScaleb.doc 5
1. General
The programs JTAG250.EXE, JTAG255.EXE, JTAG321.EXE and JTAG425 use
the JTAG port of the Intel XScale processors in conjunction with the small JTAG-
Booster:
• to program data into flash memory
• to verify and read the contents of a flash memory
• to make a memory dump
• to access an I²C Device
• to test CPU signals
All functions are done without any piece of software running in the target. No
firmware or BIOS must be written. Bootstrap software may be downloaded to
initially unprogrammed memories.
The JTAG-BOOSTER' s software is highly optimized to the JTAG chain of a
specific target CPU. To give support for all processors of the Intel XScale family,
there are three different programs on the distribution disk:
• JTAG250.EXE : Tool for Intel PXA210/250
• JTAG255.EXE : Tool for Intel PXA255/26x
• JTAG321.EXE : Tool for Intel IOP321
• JTAG425.EXE : Tool for Intel IXP425
Please contact us, if you need support for other members of the Intel XScale
family.
For latest documentation please refer to the file README.TXT on the
distribution disk.
