[ts-7000] Help me to write a C code for read temperarutere on TS-7200 (NetBSD 3.1)

[Andres Gomez <>]

I'm trying to write my own TMP124 (temperature reader) for NetBSD 3.1 on TS-7200. As Jesse off no respond my messages about this question and anyone helps me and I don't know how to read the temperature on TS-7200 with NetBSD 3.1 I'm writting a code to read it, based on Jesse Off's file: tspld.c. This script run on NetBSD 4.0 (NOT IN 3.X releases). This is the original script: http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/arch/evbarm/tsarm/tspld.c?rev=1.9&content-type=text/x-cvsweb-markup

And this my program:
#include "kernel.h"
#include <sys/systm.h>

#include "ep93xxvar.h"
#include "ep93xxreg.h"
#include "epgpioreg.h"
#include "sysmonvar.h"


struct tspld_softc {
        struct device           sc_dev;
        bus_space_tag_t         sc_iot;
        bus_space_handle_t      sc_wdogfeed_ioh;
        bus_space_handle_t      sc_wdogctrl_ioh;
        struct sysmon_wdog    sc_wdog;
        bus_space_handle_t      sc_ssph;
        bus_space_handle_t      sc_gpioh;
        unsigned const char *   sc_com2mode;
        unsigned const char *   sc_model;
        unsigned char           sc_pldrev[4];
        uint32_t                sc_rs485;
        uint32_t                sc_adc;
        uint32_t                sc_jp[6];
        uint32_t                sc_blaster_present;
        uint32_t                sc_blaster_boot;
        uint32_t                boardtemp;
        uint32_t                boardtemp_5s;
        uint32_t                boardtemp_30s;
        struct callout          boardtemp_callout;
};

void    tspld_callback __P((struct device *));

#define GPIO_GET(x)     bus_space_read_4(sc->sc_iot, sc->sc_gpioh, \
        (EP93XX_GPIO_ ## x))

#define GPIO_SET(x, y)  bus_space_write_4(sc->sc_iot, sc->sc_gpioh, \
        (EP93XX_GPIO_ ## x), (y))

#define GPIO_SETBITS(x, y)      bus_space_write_4(sc->sc_iot, sc->sc_gpioh, \
        (EP93XX_GPIO_ ## x), GPIO_GET(x) | (y))

#define GPIO_CLEARBITS(x, y)    bus_space_write_4(sc->sc_iot, sc->sc_gpioh, \
        (EP93XX_GPIO_ ## x), GPIO_GET(x) & (~(y)))

#define SSP_GET(x)      bus_space_read_4(sc->sc_iot, sc->sc_ssph, \
        (EP93XX_SSP_ ## x))

#define SSP_SET(x, y)   bus_space_write_4(sc->sc_iot, sc->sc_ssph, \
        (EP93XX_SSP_ ## x), (y))

#define SSP_SETBITS(x, y)       bus_space_write_4(sc->sc_iot, sc->sc_ssph, \
        (EP93XX_SSP_ ## x), SSP_GET(x) | (y))

#define SSP_CLEARBITS(x, y)     bus_space_write_4(sc->sc_iot, sc->sc_ssph, \
        (EP93XX_SSP_ ## x), SSP_GET(x) & (~(y)))


int main(void){
        struct tspld_softc *sc ;
        u_int16_t val;

        GPIO_SET(PFDDR, 0x0);

        /* Disable chip select */
        GPIO_SET(PFDDR, 0x0);

        val = SSP_GET(SSPDR) & 0xffff;
        int boardtemp = ((int16_t)val >> 3) * 62500;

        /* Enable chip select */
        GPIO_SET(PFDDR, 0x4);

        /* Send read command */
        SSP_SET(SSPDR, 0x8000);
}

But, when I run it, it show this messages:

toaster# ./dev
[1]   Segmentation fault (core dumped) ./dev
