leds: add Awinic AW2026 driver [LWN.net]
linux kernel patch that adds AW2026 LED driver support

5

Leds come much later. First would be to netboot some random mt7621 initramfs kernel and back up oem setup.

6

Done. Booting initramfs from SNR-CPE-ME2-Lite worked out. I also made a new dts for this router, added new target in .mk file, built openwrt image and netbooted initramfs. It worked, but not entirely. What did I do wrong?

Looks good, back up oem flash extra time, check that at least something can be restored from uboot alone, check also that wifi power levels are ok in EU/US/JP alongside where you are (iw phy shows them, but do not activate radio, changing global DFS mode usually degrades wifi transmissions)

8

LAN port doesn’t work (no link message when I plug the cable) and its LED is always lit up. WAN port shows the message when I plug the cable but its LED doesn’t light up. I can’t connect to router with ssh, web 192.168.1.1 also doesn’t work.

There’s also no 5G radio, only 2.4G:

When I backed up OEM flash with me2-lite initramfs, both radios were present in luci and LAN port was working.

Edit: I forgot to include wireless packages kmod-mt7615 and mt7663
DTS is not quite correct too. I can’t declare wan in switch0 (assuming from me2-lite’s .dts).

9

Do not program anything before in-memory image is functional.

10

What’s the next step then? I don’t understand. I didn’t program anything except for initramfs. RIght now I’m trying to figure out how to make LAN port work. I’m assuming DTS is not correct.

11

You have to tftpboot and bootm the initramfs part.
If you flashed it then IF actual caldata were near "kernel" partition it may have veen wiped forever.

12

I’ve already done that

This is what happens when I tftpboot openwrt initramfs for this router.

13

Did you create/build this image ?

14

Yessir. What I did is I took snr-cpe-me2-lite dts and changed switch0 ports (since there is only one LAN port). And I also changed gmac1 because WAN port is not number 0 but number 3. I also checked cudy-m1300-v2 dts for reference, and it’s almost the same, except for port numbers.

Then I guess your changes were incorrect and/or incomplete ?

16

I understand that and I’m trying to figure out how to fix this

Do you have them in github or something?

18

Do you mean the .dts files? No, I don’t. Do you need me to commit them to my openwrt fork?

19

Branch first... Somebody can look at them and OEM DTS and maybe assist you.

EDIT: something booting somewhat is already a lot. Problem at this point is if anything crashes it is the next driver in line showing no message. If you build it you can add debug kernel parameter.
