Re: [OpenWrt-Devel] TP-Link TL-WA901ND V2 support
Hi Jonathan,
..
Here's the relevant lines from dmesg:
ag71xx_mdio: probed
eth0: Atheros AG71xx at 0xb900, irq 4
eth0: connected to PHY at ag71xx-mdio:0c [uid=8201, driver=Generic PHY]
The PHY is at address 0x0c. So the phy mask should be 0x1000 (1 12).
I don't really understand the mask. I know it determines what phy is
selected, but I'm in the dark about the correct value.
I've tried using both b900 and 8201.
both result in a 'no PHY found with phy_mask' message.
The b900 is the address of the ethernet registers, and the 8201 is the
ID of the PHY.
set_preinit_iface() {
ifname=eth0
+ [ $(ar71xx_board_name) = tl-wa901nd-v2 ] mii-tool -R
+ /* The TP-link WA901ND V2 requires a hardware reset of
+ * its ethernet port before it will connect.
+ */
+
This looks strange. The phy core should reset the PHY automatically. Please
try
to add this line into the machine setup code, somewhere before the
'ar71xx_add_device_eth(0)' call:
ar71xx_eth0_data.reset_bit = RESET_MODULE_GE0_MAC | RESET_MODULE_GE0_PHY;
That works perfectly. Thank you! Using mii-tool was really bugging me, as
well.
Once the correct phy_mask value is determined, I'll resubmit the patch.
Ok.
Regards,
Gabor

Re: [OpenWrt-Devel] TP-Link TL-WA901ND V2 support
Included patch adds support for the TP-link WA901ND-v2. I have yet to
map out the leds and buttons, but I don't anticipate having much
problem with that. I'll push that patch through once I get it done.
This patch also adds an init script to the ar71xx platform. It checks
to see if it is running on a wa901ndv2 and brings up the ethernet port
if it is. There may be a better way to reset that phy chip, but this
is the best I've found.
Cheers,

Re: [OpenWrt-Devel] TP-Link TL-WA901ND V2 support
Hi Jonathan, OK, so, I was finally able to compile forcedeth support into the kernel. It seems that the kernel compile process prompts whether to actually compile that in. Without running V=99, I had no way of telling it to actually include forcedeth support. You don't need forcedeth support. The ethernet controller is built into the AR9132. The RTL8201CP is a PHY chip, and it should be supported by the generic phy driver. That said, I still have no ethernet support. Strangely enough, absolutely no pci devices show up in /proc/bus/pci/devices. The file is altogether empty. The AR9132 has no PCI bus at all. A couple questions: First, should I continue to document my efforts here, or create a thread in the forums? Please show me your machine setup code.

Second, when I dumped the flash, I did a 'dd if=/dev/mtd[#] of=/tmp/901V2dump[#].bin' Should I have dd'ed from mtdblock instead? The stock boot log is now up here: http://oneru.dyndns.org/openwrt/WA901NDv2/901V2BootLog.txt I do see one item that sticks out. There is a '/lib/modules/2.6.15/net/ag7100_mod.ko' in the stock firmware. Could it be a proprietary driver? I'd try to investigate it further, but I can't think of a way to transfer the file off the router.

Re: [OpenWrt-Devel] TP-Link TL-WA901ND V2 support
The stock firmware is now up at http://oneru.dyndns.org/openwrt/WA901NDv2/ The driver for the ethernet chip appears to be the the forcedeth.c driver that ships with the kernel. I haven't been successful in making the build process include that file for compilation, though. I've added CONFIG_FORCEDETH=Y it to trunk/target/linux/generic/config-2.6.32 and trunk/target/linux/ar71xx/config-2.6.32. That driver isn't added to the firmware, and the actual .config file in the build directory has it unset. What am I missing to make this driver compile? ~Jonathan Bennett ___ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
