wifi ( jorjin WG7310 ) crash over AM/DM 37x EVM

Hi:

Did you fix this issue???

Is IRQ configure issue???

Austin

Hi Prateek,

Can you please update if you solved this problem(and how you solved) or anyone from TI helped/gave you solution.

Many Thanks,

Peter

Hi,

I am using AM/DM37x board with WG7310 module from Jorjin Technologies. After integration of jorgin module with evm

when i tried to up the tiwlan0 I got following logs.After these logs it showed kernel panic.

the same problem  i got in wince  is there any update for problem?

Hi Rama,

The problem is related to the GPIO configuration.

Configure the pins as a gpio and request for gpio in board configuration file ( arch/arm/mach-omap2/board-oamp3evm.c ) as below.

#define DM37_WIFI_PMENA_GPIO   150
#define DM37_WIFI_IRQ_GPIO     149

 static int __init dm37evm_wlan_init(void)
{
        int ret;
        omap_mux_init_gpio(DM37_WIFI_PMENA_GPIO, OMAP_PIN_OUTPUT);
      
        omap_mux_init_gpio(DM37_WIFI_IRQ_GPIO, OMAP_PIN_INPUT);
        omap_mux_set_gpio(OMAP_MUX_MODE4 | OMAP_PIN_OUTPUT,DM37_WIFI_PMENA_GPIO);
        omap_mux_set_gpio(OMAP_MUX_MODE4 | OMAP_PIN_INPUT,DM37_WIFI_IRQ_GPIO);

        PRINTK("%s: start\n", __func__);
        ret = gpio_request(DM37_WIFI_IRQ_GPIO, "wifi_irq");
        if (ret < 0) {
                printk("%s: can't reserve GPIO: %d\n", __func__,
                        DM37_WIFI_IRQ_GPIO);
                return ret;
        }
                ret = gpio_request(DM37_WIFI_PMENA_GPIO, "wifi_pmena");
        if (ret < 0) {
                printk("%s: can't reserve GPIO: %d\n", __func__,
                        DM37_WIFI_PMENA_GPIO);
                gpio_free(DM37_WIFI_IRQ_GPIO);
                return ret;
        }
       
        gpio_direction_input(DM37_WIFI_IRQ_GPIO);
        gpio_direction_output(DM37_WIFI_PMENA_GPIO, 0);
               

}

call this initialization code from board init function.
