[microblaze-uclinux] Can I use assembly language code in uClinux

["Kunal Kishore" <kunalpatna@xxxxxxxxx>]

Hi all,


I want to interface some digital hardware like UART with MicroBlaze
processor. The hardware is to be written in VHDL by me and will be
downloaded on  as an IP core using Xilinx EDK. But the problem is the right software. I
don't have enough expertise in c programming. So I want to write an
assembly language code using MicroBlaze instruction set and compile with
other c programs of the uClinux dist to build the image. 


1)  Is that
possible ? If yes then can anyone suggest HOW ? Can the program be compiled by mb-gcc compiler like any other c program ?


2)  Will it be safe as I may end up overwriting the register which is being used by kernel ?


Reply please !

Thanx in advance.
