Adventures in building OpenWrt for linkit7688

[v_alex7]

Hi,
Did you figured out how to solve the patch issue? I have the same problem

[sebtop]

Hii,
i also wanted do buld OpenWrt for my linkit7688 to use packages out of the old packages feed. I applied the changes that tippy2k mentioned in the first post on this topic. In my case I changed the kernel version from 3.18.103 to 3.18.44! After I did that I got the exat same error report as mmessuri in his post on Nov 22, 2017.
This was the first Time I tried to build openwrt myself, could anyone help me with that?

Hi sebtop,
I'm getting this error too. i dont think this way work anymore. So i try something else
I didn't change the kenrel-version.mk, i did something more simple like:
In my case, the kernel version is 3.18.84, so i just copy it:

cp ./feeds/linkit/mtk-sdk-wifi/wifi_binary/mt_wifi.ko_3.18.44 ./feeds/linkit/mtk-sdk-wifi/wifi_binary/mt_wifi.ko_3.18.84
cp ./feeds/linkit/mtk-sdk-wifi/wifi_binary/mt_wifi.ko_3.18.44_all ./feeds/linkit/mtk-sdk-wifi/wifi_binary/mt_wifi.ko_3.18.84_all

It tooks a lot of time, i'm still waiting

I'll let you know if it works.

I got OpenWrt 18.06 to build with this.

Kenzu/linkit-smart-7688-feed

I had to remove some deps/packages like node libmraa and libupm.
Feel free to help, fork make a pull request or whatever

Hi @bacon,

Did this work for you? Is using mt_wifi.ko_3.18.44 as mt_wifi.ko_3.18.84 fully functional or result into some crash / undesired behavior?

@tippy2k @sebtop @mmessuri

I moved to Git openwrt 15.05 commit ID: "2c54d989b46284bc5ee5b43d4ba7c2762c2241ed" [Commit message: CC: generic: bump kernel to 3.18.44].

I assumed it may resolve any compatibility issue with WiFi module. I also assumed, build documentation here must be older (for kernel 3.18.44) and may not work for latest openwrt commit (with kernel 3.18.84).

I did NOT observe any tag or patch errors mentioned here then.
I observed minor download glitch for few packages (i.e. mjpg-streamer, libmraa etc. which I downloaded manually and placed in "dl" directory).

It seems to build fine and creates complete image. Do you see any issue with this approach?
Do you have any better approach which may have worked out for you already?

Any suggestion will be highly appreciated. Thanks in advance!
