Custom build AP143 to use with CF-WR752AC

For Developers
1

I've made a custom build using the AP143 target and OpenWRT 18.06-4.
I know this is not the standard approach. I managed to boot the kernel images that I've flash using the bootloader but it seems that the device can't mount the file system.

I'm not sure how to fix this and any feedback on how to proceed would be super appreciated. I've other samples of the CF-WR752AC laying around so I can make a backup of some data from the original firmware partitions and make a backup of them through the bootloader.

your kernel command line is missing rootfs type

3

This mtd layout is totally different to the one in your kernel bootlog...
You should fix that first!

How did you boot or flash the resulting openwrt image?

Does everything work with the initram image?
If not, then concentrate first on making everything work apart the rootfs with a initram openwrt image.

Edit: And why not porting your device to the ath79 target instead of the deprecated ar71xx target?

:+1: on ath79. Once you get a hang of DTS, it’s a lot easier to configure.

(Also, no new ports are being accepted on ar71xx.)

5

Appreciate the feedback I'll look into ath79 and DTS to proceed with the port. I guess there's a guide here on forum on the website.

How did you boot or flash the resulting openwrt image?

I've managed to access the device boot loader and load the binaries through tftp commands. Then I've used bootm to boot the kernel at the address I uploaded the files.

I've decided to give a try as the AP143 has a target ready. It worked with a couple of different boards that I've tried before. I know this was a lazy approach but decided to give a try anyway.

This means you dont have anything in your flash memory and your kernel does search for the rootfs magic bytes on flash memory.
In almost every device the default loadaddr is in ram and not in flash, so there was no rootfs on your flash memory.
As i said before, use the initram openwrt image to boot your kernel and rootfs directly from ram with tftpboot and make all apart from rootfs in flash working before.

I think if you are at the point of all hw is working as it should, the step with the rootfs in flash will be almost clear to you, as you need to access the flash for ath9k firmware and device specific mac addresses.

7

A brief update to this topic, after adjusting the memory layout I've managed to boot the OS properly. The 5GHz radio is not working though.
I will look into porting DTS after getting both radios working on ar71xx as a starting guideline.

Also I'm attaching the OEM firmware bootlog

I've installed the ath10k kmod and QCA9888 firmware on menu config. I've also tried with the ct versions and got the same results. Should I look into the PCI first?

definitely

adding the ath79_register_pci() and the pci.h on the match file did the trick

I'll check some led definitions and start to work with the DTS port for this device. I've some ar71xx devices that I would like to port myself. This could be a nice starting point.

Another brief update I've made a fork from master and started to work on the port fir ath79 target. If you interested in this device you can check my commits at my fork.

I'm open to more feedback on how to proceed, also thank's for the earlier feeback it help me quite a lot at the beginning.

current bootlog indicates I've messup the partition definitions I'm looking into this before proceeding.

11

Some notes on your ath79 port:

Firstly:
As you define linux,default-trigger = "xxx" in dts, drop ucidef_set_led_netdev ... from the file 01_leds.
The definition in the dts deprecates the 01_leds handling.

Secondly:
poll_interval in gpio-keys is not used as this was only for the compatible type gpio-keys-polled.
So drop this also...

Thirdly:
In your flash definition drop kernel and rootfs and replace it with only firmware...
The splitting in kernel and rootfs should be handled by the firmware splitter...
Check other commits or devices for examples.

Lastly:
There are many style issues and probably other stuff that i've overseen on first sight, but keep your work going and good luck to fix up everything.
Feel free to ask for help.

12

Appreciate the feedback, I've added most of the suggestions already.

After testing the device boots properly and both radios are able provide ssids. The mac address on the 5GHz is 12:34:56:78:90 although I've used the same ath10k cal_data from my ar71xx target. After checking the backup on my art partition I can see that I didn't overwrite anything I shouldn't.

Are there any good readings or books I could read to improve on my own? A better theoretical background could probably help me in my current, and future, ports.

Here are another suggestions...

Your firmware node should look like:

partition@20000 {
	label = "firmware";
	reg = <0x20000 0xfc0000>;
	compatible = "denx,uimage"; 
};

If you can not find your real mac in your flash, you can send me a pm with your real mac on your device label and a dump of your flash partitions...
Use this scripts for doing a full backup: https://openwrt.org/docs/guide-user/installation/generic.backup#create_full_mtd_backup

Congratulations regarding the progress you have made so far!

Will definitely make a pull request once the 5GHz radio has the correct mac address. Just not really sure how to fix it.

The hardware specs of the CF-WR752AC are currently not listed at wikidevi. Would be nice if you could create a page at wikidevi for this device (you will need the hardware info anyways for the PR, see below).

I've created the wikidevi page. I'll try to improve it though.

Cheers

I've added this one on my last commit

Your firmware node should look like:

partition@20000 {
	label = "firmware";
	reg = <0x20000 0xfc0000>;
	compatible = "denx,uimage"; 
};

I've sent you the MTD backups I made. Let me know if you need more information.

Hey lads once again thanks with the help for porting this device for openwrt.
I have made the Pull request, it probably needs some changing as the leds are not fully operational (only got the blue one working).

Will probably continue the discussion on github from now on.

Cheers
