I'm working on a AU1100, with MMU; from the datasheet:
The Au1100 processor is a complete SOC based on the MIPS32
Designed for maximum performance at very low power, the Au1100 runs up
to 500 MHz.
Power dissipation is less than 0.25 watt for the 400 MHz version.
Highly integrated with onchip
SDRAM, SRAM/Flash EPROM memory controllers, a LCD controller, 10/100
Controller, USB Host and Device, UARTs (3), and GPIOs (up to 48,24
Au1100 processor runs a variety of operating systems, including
Windows® CE.NET, Linux
and VxWorks. Moreover, the integration of peripherals with the unique,
MIPS-compatible core provides low system cost, small form factor, low
requirement, simple designs at multiple performance points and thus,
short design cycles.
For the configuration it was not very direct:
I compiled kaffe on PC
# ./configure --with-engine=intrp --enable-pure-java-math --without-esd
then I changed
uncommenting the line:
#MAYBE_PEERLESS_KAFFE_AWT = awt-implementations
and gave the make.
Then I copied
libraries/javalib/rt.jar on the AMD built tree of kaffe (same place)
on AMD /home/AMDgiammy/kaffe-1.1.5/kaffeawt.jar
Then I configure the AMD kaffe:
./configure --with-jikes=no --with-engine=intrp
--enable-pure-java-math --without-esd --without-kaffe-x-awt
Removed from file kaffe-1.1.5/Makefile
and changed in the file
kaffe-1.1.6/libraries/Makefile the raw
SUBDIRS = clib javalib extensions
SUBDIRS = clib extensions
and finally started the make
