Porting guide ar71xx to ath79?

Mynzer · June 25, 2018, 4:31pm

Maybe I was not clear explainin what i did before when we tried the correction on the ath9 eeprom helper, the change that i did that ends working was...

Changin this....

"tplink,tl-wdr3600"|\
	"tplink,tl-wdr4300")
		ath9k_eeprom_extract "art" 20480 1088
		;;
	"tplink,tl-wr740n-v2"|\
	"tplink,tl-wr2543-v1"|\
		ath9k_eeprom_extract "art" 20480 1088
	"ubnt,unifi")
		ath9k_eeprom_extract "art" 4096 2048
		;;
	*)
		ath9k_eeprom_die "board $board is not supported yet"
;;

To this

"tplink,tl-wdr3600"|\
	"tplink,tl-wdr4300")
		ath9k_eeprom_extract "art" 20480 1088
		;;
	"tplink,tl-wr740n-v2"|\
	"tplink,tl-wr2543-v1")
		ath9k_eeprom_extract "art" 4096 2048
	"ubnt,unifi")
		ath9k_eeprom_extract "art" 4096 2048
		;;
	*)
		ath9k_eeprom_die "board $board is not supported yet"
;;

I put that with the output of the working helper dmesg mentioned it in my previous post, but maybe was not clear, sorry if this caused confusion.

the first time it was setup for ath9k_eeprom_extract "art" 20480 1088 not ath9k_eeprom_extract "art" 4096 2048
review the discussion
and the second example should not be good..

Mynzer · June 25, 2018, 4:37pm

@lucize, yes , I was correcting my post, but you notice it before I put the correct info

lucize · June 25, 2018, 4:40pm

this

 	"tplink,tl-wr740n-v2"|\
	"tplink,tl-wr2543-v1"|\
 	"ubnt,unifi")
 		ath9k_eeprom_extract "art" 4096 2048
 		;;

is better than

and it's missing a ;; in the between of the case

Mynzer · June 25, 2018, 4:44pm

Ok, let me try your pull request, and I've report back, sorry if I've caused confusion.

@juppin Thank so much, now it showed up))

Is this for a hw mod or has the device a mmc slot by default?
Which device is it?

Deoptim · June 25, 2018, 7:39pm

Is this for a hw mod or has the device a mmc slot by default?
Yes, its for hardware mod.

Which device is it?
tl-mr3420-v1 with usb support.

I have some questions about porting this device on ath79:

I used default configuration from ar7240_tl-wr740n-v2.dts for (eth0 eth1 mdio0).
But it works only with this configuration of switch0:

	"tplink,tl-mr3420-v1")
		ucidef_set_interfaces_lan_wan "eth1.1" "eth0"
		ucidef_add_switch "switch0" \
			"0@eth1" "1:lan:4" "2:lan:3" "3:lan:2" "4:lan:1"

Where mdio0 is used(4.14 log):

[    0.485863] libphy: Fixed MDIO Bus: probed
[    1.455188] libphy: mdio: probed
[    1.460663] mdio-bus.0: Found an AR7240/AR9330 built-in switch

[    2.156585] eth1: Atheros AG71xx at 0xba000000, irq 5, mode:GMII

Original configuration (ar71xx):

		ucidef_set_interfaces_lan_wan "eth0.1" "eth1"
		ucidef_add_switch "switch0" \
			"0@eth0" "1:lan:4" "2:lan:3" "3:lan:2" "4:lan:1"

Where it use mdio1(4.9 log):

[    0.975162] libphy: Fixed MDIO Bus: probed
[    0.996875] libphy: ag71xx_mdio: probed

[    2.315288] eth1: Atheros AG71xx at 0xb9000000, irq 4, mode:MII

How can I swap eth0 <=> eth1?
As I understand it is necessary to use mdio1...

Mynzer · June 25, 2018, 8:20pm

@lucize @juppin I started again with a fresh clone of the TLWR2543ND git pull request, to stay sure that I don't bring my mistake in the ath9 eeprom helper, everything is working, including the aht79 to ath79 sysupgrade procedure . many thanks for all your help. You guys spot very quick when something is wrong.

Mr @lucize, In case that you still have some time to check it and still are interested, Could we review the status of the Linksys E2100L?

lucize · June 25, 2018, 10:00pm

I would like a dmesg if possible, do you have tft and bootm in this one ? or something that can run from ram in uboot ?

lucize · June 25, 2018, 10:02pm

there was a comment in github that you need to do it in ath79.dtsi

Mynzer · June 25, 2018, 10:42pm

@lucize Yes, in this device have stock u-boot, it have tftboot and bootm. Here is a complete bootlog from the last openwrt image in the archive and here is the old github commit for this device

can you try a build without

	memory@0 {
		device_type = "memory";
		reg = <0x0 0x4000000>;
	};

and see if the amount of memory is properly detected ?
you can report success here or on https://github.com/openwrt/openwrt/pull/1091

Thanks!

lucize · June 26, 2018, 11:59am

at a first glance, I see no OF support for this switch we would need to add it, I'll prepare a dts anyway and we'll test further

Mynzer · June 26, 2018, 5:48pm

The new build without

	memory@0 {
		device_type = "memory";
		reg = <0x0 0x4000000>;
	};

The memory is properly detected, here is th dmesg if you want to review it

Hello again.
How can I owerride gpio led in dsti profile with profile from dst configuration?
For example, i have profile with common hw-layout ar7241_tl-mr3x20-v1_tl-wr841-v7.dtsi:

...
	// Submitted separately to be able to disable.
	usb-leds {
		compatible = "gpio-leds";

		led3g {
			label = "tp-link:green:3g";
			gpios = <&gpio 8 GPIO_ACTIVE_LOW>;
			default-state = "off";
			trigger-sources = <&hub_port>;
			linux,default-trigger = "usbport";
		};
	};
...

Now I want to disable this led in dst profile ar7241_tl-wr841-v7.dts:

...
#include "ar7241_tl-mr3x20-v1_tl-wr841-v7.dtsi"
...
&usb-leds {
	compatible = "gpio-leds";

	status = "disabled";
};
...

But compiler gets this error:

Error: ../dts/ar7241_tl-wr841-v7.dts:10.2-8 syntax error
FATAL ERROR: Unable to parse input tree

(if I comment those lines - then it compile fine)

There is no status = "disabled" for leds!

Why are you doing this?

You should define it only if you need it instead of disabling it afterwards!

Sorry, but you were wrong.
I successfully disabled the led.

status "disabled" or "okey" is the scope of the visible variable (or in this case the groups of variables enclosed in curly braces). By default all variables in "label {...}" have status "okey".

I created the following ar7241_tl-mr3x20-v1_tl-wr841-v7.dtsi (common profile):

		led3g: led3g {
			label = "tp-link:green:3g";
			gpios = <&gpio 8 GPIO_ACTIVE_LOW>;
			default-state = "off";
			trigger-sources = <&hub_port>;
			linux,default-trigger = "usbport";
		};

And one of dts profile:

&led3g {
	status = "disabled";
};

And it disabled (it does not exist) on worked device.

By the way, to quickly check dts profiles for errors, you can use the following commands:

cpp -nostdinc -I ~/Openwrt-trunk/build_dir/target-mips_24kc_musl/linux-ath79_tiny/linux-4.14.50/include -undef -x assembler-with-cpp ~/Openwrt-trunk/target/linux/ath79/dts/file.dts > file.tmp.dts
~/Openwrt-trunk/build_dir/target-mips_24kc_musl/linux-ath79_tiny/linux-4.14.50/scripts/dtc/dtc -O dtb -o file.dtb file.tmp.dts
