I study programming for embedded systems. I run barebox for mips as an exercise. Work on the disassembler will allow me to get better acquainted with the MIPS instruction set. I'm on vacation now. I plan to finish disassembler after the vacation ends. Options -s and -a are not working in the current version, I plan to fix it. If you think the disassembler pulls too much code from other projects, I'll keep the finished version in my separate branch on github. -- Smirnov Alexander _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
