i want to use the UID instruction in my application or library, but the sde toolchain on support to compile bootloader or kernel. how to use it to compile a application or library? or does any other cross-tool support UID instruction? thanks for any hints
I assume that you mean the UDI instruction. You could consider the TimeSys Linuxlink MIPS distribution see http://www.timesys.com/releases/home_bdy_news.php?show_article=1265 which will include MIPS SDE configured as a full Linux MIPS cross-toolchain.
