From mboxrd@z Thu Jan 1 00:00:00 1970 From: Celejar Date: Mon, 12 Apr 2010 23:33:13 -0400 Subject: Asus 520gu Message-ID: <20100412233313.542e9b8d.celejar@gmail.com> List-Id: MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit To: b43-dev@lists.infradead.org Hi, The recent OpenWrt release, along with the recent b43 work on the LP PHY, inspired me to dig up my Asus 520gu and see what it could do. Some documentation on the hardware is here: http://mightyohm.com/blog/2008/10/detailed-specs-for-the-asus-wl-520gu-uber-hacking-platform/ OpenWrt (Blackfire) flashes and loads fine: root at OpenWrt:/# uname -a Linux OpenWrt 2.6.32.10 #20 Tue Apr 6 15:53:48 CEST 2010 mips GNU/Linux [dmesg below] This thing apparently has a Broadcom 5354 (Chip ID) radio, as reported by b43. I don't know how to get further information about it - lspci returns no output on this box - I guess there's no pci bus? OpenWrt has the radio disabled out of the box. When I enable it, the system seems to hang. I say seems, since I don't have serial access - all I know is that my telnet connection dies / freezes, and I can't log in again. All I can do is reflash. Something does seem to be happening, though - the radio is sending out beacons, as can be seen from a nearby box: Cell 03 - Address: 00:22:15:53:42:17 Channel:5 Frequency:2.432 GHz (Channel 5) Quality=55/70 Signal level=-55 dBm Encryption key:off ESSID:"OpenWrt" Bit Rates:1 Mb/s; 2 Mb/s; 5.5 Mb/s; 11 Mb/s; 6 Mb/s 9 Mb/s; 12 Mb/s; 18 Mb/s Bit Rates:24 Mb/s; 36 Mb/s; 48 Mb/s; 54 Mb/s Mode:Master Extra:tsf=00000000006ef183 Extra: Last beacon: 219ms ago IE: Unknown: 00074F70656E577274 IE: Unknown: 010882848B960C121824 IE: Unknown: 030105 IE: Unknown: 050401020000 IE: Unknown: 2A0100 IE: Unknown: 32043048606C IE: Unknown: DD180050F2020101000103A4000027A4000042435E0062322F00 I cannot, however, get the nearby box to associate with the OpenWrt box, no matter what I try. What is the status of b43 for this device? Is this sort of freeze / crash something still expected at this stage? I know that without proper console / serial access, there's a limit to how useful my information is, but does anyone have any suggestions, or directions for further reading / testing / etc.? Thanks for your work on this driver. root at OpenWrt:/# dmesg Linux version 2.6.32.10 (openwrt at wrt1.marcant.net) (gcc version 4.3.3 (GCC) ) #20 Tue Apr 6 15:53:48 CEST 2010 CPU revision is: 00029029 (Broadcom BCM3302) ssb: Core 0 found: ChipCommon (cc 0x800, rev 0x14, vendor 0x4243) ssb: Core 1 found: Fast Ethernet (cc 0x806, rev 0x09, vendor 0x4243) ssb: Core 2 found: MIPS 3302 (cc 0x816, rev 0x08, vendor 0x4243) ssb: Core 3 found: USB 2.0 Host (cc 0x819, rev 0x02, vendor 0x4243) ssb: Core 4 found: MEMC SDRAM (cc 0x80F, rev 0x04, vendor 0x4243) ssb: Core 5 found: IEEE 802.11 (cc 0x812, rev 0x0D, vendor 0x4243) ssb: Core 6 found: Roboswitch (cc 0x81C, rev 0x02, vendor 0x4243) ssb: Found rev 0 PMU (capabilities 0x04A63400) ssb: Initializing MIPS core... ssb: set_irq: core 0x0806, irq 4 => 4 ssb: set_irq: core 0x0816, irq 5 => 2 ssb: set_irq: core 0x0812, irq 2 => 5 ssb: after irq reconfiguration ssb: core 0x0800, irq : 2(S) 3* 4 5 6 D I ssb: core 0x0806, irq : 2(S) 3 4* 5 6 D I ssb: core 0x0816, irq : 2(S)* 3 4 5 6 D I ssb: core 0x0819, irq : 2(S) 3 4 5 6* D I ssb: core 0x080f, irq : 2(S) 3 4 5 6 D I* ssb: core 0x0812, irq : 2(S) 3 4 5* 6 D I ssb: core 0x081c, irq : 2(S) 3 4 5 6 D I* ssb: Sonics Silicon Backplane found at address 0x18000000 Serial init done.
