 | Using CW for ARMDS v1.2 I am building an embedded app, linked at 0. If I
build a small test app it loads fine. If I exceed a certain size, it either
doesn't link or doesn't load properly. In the code sample before, if I make
the const char array smaller than 898 bytes, the code loads fine. If 898 or
larger, it overwrites the 32-bit word at 0x0 with 0. Add more bytes and the
word at 0x4 gets overwritten with zero also, etc.
Location zero has the "bl InitReset" from the exception vectors. The build
includes Cstartup.s, Usart.c, retarget.c, startup.c and the code below.
Compiler command line equivalent shows as: -O0 -W -DUSE_SERIAL_PORT
Linker CL equivalent shows as: -remove (dbg) -entry scott -ro-base
0x00000000 -nolocals -list C:\Test\Source\scotty.lst -first
cstartup.o(reset)
Any suggestions?
#include "stdio.h"
int main(void);
void argh(void);
int main(void)
{
printf("Hello?");
argh();
}
//const char big[898] = { 'a', 'b', 'c', 'd', '\0' }; // fails
const char big[897] = { 'a', 'b', 'c', 'd', '\0' }; // works
void argh( void )
{
printf(" %s", &big);
}
