3. Implementation Information
This chapter summarizes some information about the implementation of the
JTAG-Booster and describes some restrictions.
?
?
The JTAG-Booster currently uses Boundary Scan to perform Flash
programming. EJTAG is not used.
The software assumes the following scheme for connecting the Flash-
EPROM to the AMD Alchemy Solutions Processors. Please contact us, if you
need support for a different method.

1.) All other signals are hold static during flash programming. The state of
these signals is defined in the Initialization file.

Default endianess is "Little Endian". Use the option /BIG for big endian
support.
Physical address range for static memory and peripherals is limited to
512MByte (MIPS32 specific). For memory accesses with boundary scan, the
address lines RAD29, RAD30 and RAD31 are not modified.
Support for NAND flashes is not included as standard functionality, but can
be provided on customers request (AMD Alchemy Solutions Au1550
Processor only).
