I have a ARM7 with build in ROM service which is all in Thumb code. I want to call it from my program which is ARM mode.
How can I tell the GNU compiler/linker to create a BX to jump to the ROM entry point? Do I need to setup *.ld or compiler options?
Any idea is welcome.

Take a look to: http://www.keil.com/download/docs/298.asp
The technique should also work with the GNU Compiler.
