[arm-gnu] Can I use arm-none-linux-gnueabi with armv4 CPU?

["aska_chang" <aska_chang@xxxxxxxxxxxxxxxx>]

Hello all,

My  system uses an ARM v4 instruction CPU  and I plan change compiler  from arm-linux-gcc to arm-none-linux-gnueabi-gcc.


For now I can compile kernel 2.6.21 (arm-none-linux-gnueabi-gcc ) by adding option "-march=armv4" and open EABI support in kernel config.

The zImage can be generated successfully and works with  busybox of OABI format (arm-linux-gcc).


But kernel hangs when calls busybox  and the busybox  is the EABI format (arm-none-linux-gnueabi-gcc ).


At first, I found  when I tried to compile busybox with arm-none-linux-gnueabi-gcc ,  the compiler will link 

library of armv4t  even I added  "-march=armv4".


So  I  searched the folder of  tool-chain  and found the C library  is only for armv4t , thumb2 and armv5.


My question is can I use  arm-none-linux-gnueabi-gcc  to compile user application and runs on an armv4 platform ?

or I can use the armv4t library to compile and link  but need add some compile /link option into my makefile?



Thank you very much.
