The boot loader never configured the sys_nirq2, I have sent a patch for= u-boot to do this, but it is said that the kernel should take care of this. We did not had jack detection working with upstream u-boot, kernel (I h= ave patched u-boot so I have not seen this issue). Now if the board is booted without HS connected, upon connecting the HS= we will recognize it and it should be all fine. So yes this was the reason why Russell had issues with audio. --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html From mboxrd@z Thu Jan 1 00:00:00 1970 From: peter.ujfalusi@ti.com (Peter Ujfalusi) Date: Fri, 06 Jul 2012 11:22:55 +0200 Subject: [PATCH 1/2] ARM: OMAP: board-4430sdp: MUX configuration for sys_nirq2 In-Reply-To: References: <1341564590-14024-1-git-send-email-peter.ujfalusi@ti.com> Message-ID: <4FF6AE6F.4000808@ti.com> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org On 07/06/2012 11:02 AM, Shilimkar, Santosh wrote: > On Fri, Jul 6, 2012 at 2:19 PM, Peter Ujfalusi wrote: >> The sys_nirq2 is used for twl6040, make sure the pin is configured >> correctly. >> >> Signed-off-by: Peter Ujfalusi >> --- > Should remove the boot-loader pin-muxing dependency. > Was this the reason, Audio had some issues on OMAP4430 > SDP as reported by Russell ?
