Hi,
I am trying to use sdcc (pic14) with a pic16f876a. The compilation works
but the program does not.
Here is the source, test.c:
#################
#define __16f876a
#include "pic14/pic16f876a.h"
// Setup chip configuration
__code unsigned short __at(0x2007) _conf = (_CP_OFF &
_WDT_OFF &
_BODEN_OFF &
_PWRTE_ON &
_HS_OSC &
_LVP_OFF);
void main(void)
{
TRISB = 0x00; // PORT B all output
PORTB = 0xFF; // Enable all
while(1) {
}
}
#################
These are the commands I use to compile:
/opt/cross/bin/sdcc -c -mpic14 -p16f876a -I
/opt/cross/share/sdcc/non-free/include/ --use-non-free test.c
gpasm -c test.asm
gplink test.o /opt/cross/share/sdcc/non-free/lib/pic14/pic16f876a.lib
/opt/cross/share/sdcc/lib/pic14/libsdcc.lib
-I/opt/cross/share/sdcc/include/ -a inhx8m -O 1 -o test.hex
Hardware: Just two LEDs at RB2 and RB3 (which stay off).
> sdcc --version
SDCC :
mcs51/gbz80/z80/z180/r2k/r3ka/ds390/pic16/pic14/TININative/ds400/hc08/s08 3.1.5
#7873 (Jun 10 2012) (Linux)
I use a bootloader, but the program also does not work when flashed
directly.
Changing
STARTUP code 0x0000
nop
pagesel __sdcc_gsinit_startup
goto __sdcc_gsinit_startup
to
STARTUP code 0x0000
nop
pagesel _main
goto _main
in test.asm gives a working program (the leds are on). Another asm
program compiled with gputils also works.
What may be the problem here?
Kind Regards,
Vinzenz
