And with this particular commit, all the bits needed to get FreeBSD-HEAD running natively on this unit are now in the tree. The process is documented here: http://code.google.com/p/freebsd-wifi-build/wiki/TpLinkTLWR1043ND I haven't yet tried building and testing a sysupgrade image, so please don't ask me how to update it via the default firmware webui. So to play this game you'll (for now) require a serial console. I do however have the unit running as a 2.4ghz 11n hostap, natively booting from flash with a 64k flash partition to store configuration data on. My work here is done. :-) Adrian On 24 November 2011 15:37, Adrian Chadd <adrian@freebsd.org> wrote: > Author: adrian > Date: Thu Nov 24 07:37:19 2011 > New Revision: 227926 > URL: http://svn.freebsd.org/changeset/base/227926 > > Log: > Now that I've brought up FreeBSD via flash, I've discovered that > the second-last 64k seems to be the default firmware board configuration > area. > > Since I have no idea whether uboot uses it or not - and it's prefixed > with an atheros eeprom signature (0xaa55), I figure the safest thing > to do is mark it as read-only. > > I've modified my local tplink firmware building program to generate > a board configuration section - which is separate to this partition. > It's located in the 64k _before_ this particular 64k. > > The firmware build program from OpenWRT never initialises those > values and the firmware images from tplink also leave it 0x0, so I > don't currently know what the exact, correct details should be. > > Modified: > head/sys/mips/conf/TP-WN1043ND.hints > > Modified: head/sys/mips/conf/TP-WN1043ND.hints > ============================================================================== > --- head/sys/mips/conf/TP-WN1043ND.hints Thu Nov 24 07:33:41 2011 (r227925) > +++ head/sys/mips/conf/TP-WN1043ND.hints Thu Nov 24 07:37:19 2011 (r227926) > @@ -26,7 +26,8 @@ hint.ath.0.eepromaddr=0x1fff1000 > # 128k: uboot > # 1024k: kernel > # 4096k: rootfs > -# 2880k: unknown > +# 2816: unknown > +# 64k: board config? > # 64k: ART > # > # from printenv: > @@ -37,8 +38,9 @@ hint.ath.0.eepromaddr=0x1fff1000 > # So: > # 128k: uboot > # 2048k: kernel > -# 5888k: rootfs > -# (todo: 64k: config) > +# 5824k: rootfs > +# 64k: config > +# 64k: board config? > # 64k: ART > > hint.map.0.at="flash/spi0" > @@ -55,19 +57,38 @@ hint.map.1.readonly=1 > > hint.map.2.at="flash/spi0" > hint.map.2.start=0x00220000 > -#hint.map.2.end=0x007e0000 > -hint.map.2.end=0x007f0000 > +hint.map.2.end=0x007c0000 > hint.map.2.name="rootfs" > hint.map.2.readonly=1 > > -#hint.map.3.at="flash/spi0" > -#hint.map.3.start=0x007e0000 > -#hint.map.3.end=0x007f0000 > -#hint.map.3.name="cfg" > -#hint.map.3.readonly=1 > +hint.map.3.at="flash/spi0" > +hint.map.3.start=0x007c0000 > +hint.map.3.end=0x007d0000 > +hint.map.3.name="cfg" > +hint.map.3.readonly=0 > > +# I'm not sure what this is! > +# > +# It does however start with "55 aa" which is an AR5416 EEPROM > +# magic value, followed by what looks like a set of ethernet > +# MAC addresses, then a bunch of what looks like my local firmware > +# board configuration. > +# > +# For now, I'm going to leave this particular chunk of flash > +# alone. > +# > hint.map.4.at="flash/spi0" > -hint.map.4.start=0x007f0000 > -hint.map.4.end=0x00800000 > -hint.map.4.name="art" > +hint.map.4.start=0x007d0000 > +hint.map.4.end=0x007e0000 > +hint.map.4.name="unknown" > hint.map.4.readonly=1 > + > +# This is radio calibration section.
