Boot fail on OMAP3430SDP

Boot fail on OMAP3430SDP

[Sripathy, Vishwanath]

Hi,

I am observing that image built using omap3_pm_defconfig on Kevin's pm branch does not seem to boot on OMAP3430 SDP board. It just stops after printing "Uncompressing Linux... done, booting the kernel". I am using console=ttyS0 as part of my bootargs. Any hints?

Probably Tony will be the best to answer this, but... This code shouldn't get executed I think (the one producing above prints)..

Above clocks are declared for omap2 only (in arch/arm/mach-omap2/clock24[20,30]_data.c), and even this clk_get calls are
inside of a supposedly omap2 only execution in arch/arm/plat-omap/gpio.c:

static int __init _omap_gpio_init(void)
{
...
...
#if defined(CONFIG_ARCH_OMAP2)
	if (cpu_class_is_omap2()) {
		gpio_ick = clk_get(NULL, "gpios_ick");
		if (IS_ERR(gpio_ick))
			printk("Could not get gpios_ick\n");
		else
			clk_enable(gpio_ick);
		gpio_fck = clk_get(NULL, "gpios_fck");
		if (IS_ERR(gpio_fck))
			printk("Could not get gpios_fck\n");
		else
			clk_enable(gpio_fck);

		/*
		 * On 2430 & 3430 GPIO 5 uses CORE L4 ICLK
		 */
#if defined(CONFIG_ARCH_OMAP2430)
		if (cpu_is_omap2430()) {
			gpio5_ick = clk_get(NULL, "gpio5_ick");
			if (IS_ERR(gpio5_ick))
				printk("Could not get gpio5_ick\n");
			else
				clk_enable(gpio5_ick);
			gpio5_fck = clk_get(NULL, "gpio5_fck");
			if (IS_ERR(gpio5_fck))
				printk("Could not get gpio5_fck\n");
			else
				clk_enable(gpio5_fck);
		}
#endif
	}
#endif
...
}

So, I guess your board is trying to get initialized as omap2 somehow...

Sergio

Isn't cpu_class_is_omap2() valid for OMAP3 as well?

Yeah. The above should be just if (cpu_is_omap24xx()) instead.
But that's just a warning and should not matter for the boot
issue.

To me it looks like the early_printk works, but the 8250 serial
console never gets initialized?
