I first got redboot source from here:
and went to here to install the tool chain:
http://ecos.sourceware.org/getstart.html
wget --passive-ftp ftp://ecos.sourceware.org/pub/ecos/ecos-install.tcl
The installation tool may then be invoked as follows:
sh ecos-install.tcl
and did a make ap51
It runs most of the way until the end where it dies.
mipsisa32-elf-objcopy --strip-all /home/ubuntu/redboot_mini/redboot/ap51/rom/install/bin/redboot.img
Seems like the redboot.img is not being created somehow. Any help here?
