I noticed on my ERL, which has a fairly recent build of HEAD on it (r279016M), that a two serial ports are probed during the kernel's autoconfiguration. uart1: on obio0 uart1: console (115200,n,8,1) uart1: fast interrupt uart0: on obio0 uart0: console (115200,n,8,1) uart0: fast interrupt Obviously, one of these is the serial port console of the machine. I was wondering if the second serial port was semi-easily accessible. Examining the motherboard of the ERL closely, there's a place where some header pins could be soldered in - there are just empty through-holes on the PCB. Does anybody know what pins from what devices are available on these holes? I'd like to be able to access the second serial port on the machine, and it seems not unlikely that a few of the uart's signals might show up on the headers that could be soldered into the holes. Thanks for any information. -Kurt From owner-freebsd-mips@FreeBSD.ORG Tue Feb 24 09:43:30 2015 Return-Path: Delivered-To: freebsd-mips@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:1900:2254:206a::19:1]) (using TLSv1.2 with cipher AECDH-AES256-SHA (256/256 bits)) (No client certificate requested) by hub.freebsd.org (Postfix) with ESMTPS id D29C9BBE for ; Tue, 24 Feb 2015 09:43:30 +0000 (UTC) Received: from mail.as41113.net (mail.as41113.net [91.208.177.22]) by mx1.freebsd.org (Postfix) with ESMTP id 96F559E9 for ; Tue, 24 Feb 2015 09:43:29 +0000 (UTC) Received: from [172.21.87.41] (193.98.9.212.in-addr.arpa [212.9.98.193]) (using TLSv1.2 with cipher ECDHE-RSA-AES128-GCM-SHA256 (128/128 bits)) (No client certificate requested) (Authenticated sender: lists@rewt.org.uk) by mail.as41113.net (Postfix) with ESMTPSA id 3krwLL07jjz1N1yB for ; Tue, 24 Feb 2015 09:43:21 +0000 (GMT) Message-ID: <54EC47B8.7040507@rewt.org.uk> Date: Tue, 24 Feb 2015 09:43:20 +0000 From: Joe Holden User-Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Thunderbird/31.4.0 MIME-Version: 1.0 To: freebsd-mips@freebsd.org Subject: Re: ERL second serial port?
