The kernel I used is linux-2.6.10_mvl401_LSP_01_30_00_082.
I want to use the VLYNQ driver (linux-2.6.10_mvl401_LSP_01_30_00_082\arch\arm\mach-davinci\vlynq) in the user space. So I write a very simple application as follow:
/** \file vlynq_sample.c
\brief DaVinci Vlynq Sample App
This file contains DaVinci Vlynq Controller Test code.

printf("VLYNQ MASTER :Data receive completed.\n\r");
}
The Makefile I used is as follow:

When I didn’t include the following header file “<linux/module.h> <asm/io.h> <asm/arch/hardware.h><asm/arch/vlynq/vlynq_os.h><asm/arch/vlynq/vlynq_dev.h>”, it compile successful.
The compiling information is as follow:
/home/dm6467_140/opt/mv_pro_4.0.1/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc -g -s -I /home/dm6467_140/opt/mv_pro_4.0.1/montavista/pro/devkit/lsp/ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/include -static -c saVlynq.c -o saVlynq.o
saVlynq.c: In function `main':
saVlynq.c:50: warning: return type of 'main' is not `int'
/home/dm6467_140/opt/mv_pro_4.0.1/montavista/pro/devkit/arm/v5t_le/bin/arm_v5t_le-gcc -g -s -I /home/dm6467_140/opt/mv_pro_4.0.1/montavista/pro/devkit/lsp/ti-davinci/linux-2.6.10_mvl401_LSP_01_30_00_082/include -static saVlynq.o -o saVlynq
But when I include the following header file “<linux/module.h> <asm/io.h> <asm/arch/hardware.h><asm/arch/vlynq/vlynq_os.h><asm/arch/vlynq/vlynq_dev.h>” just as the above source code, it compile wrong. Even I didn’t include <asm/io.h>, it will be wrong. Because the vlynq_dev.h file also include the hardware.h file.
The compiling information is as follow:
