Subject: OMAP3530 USB host problems
Date: Fri, 20 Feb 2009 11:15:36 -0700 [thread overview]
Message-ID: <499EF348.6020302@mlbassoc.com> (raw)
I have a 3530 board (similar to the OMAP3EVM) and I'm trying
to get the USB host working. Sadly, this is failing, but I
don't quite see why. From drivers/usb/host/echi-omap.c:
/* Wait for TLL to be Active */
timeout = 1000;
while ((cm_read_mod_reg(CORE_MOD, OMAP2430_CM_IDLEST3)
& (1 << OMAP3430ES2_ST_USBTLL_SHIFT)))
{
if (--timeout <= 0) {
printk(KERN_ERR "USB TLL is unavailable\n");
return -ENODEV;
}
cpu_relax();
}
Any clues on why this might be? How do I solve it?
