Missing Mediatek MT7628 EVB target profile in latest LEDE master

Hi,

We are using MT7628 based SKYLAB EVB , we want to build the latest 17.01.4 LEDE-master from LEDE github for "MediaTek MT7628 EVB" as Target Profile. But we are not able find "MediaTek MT7628 EVB" in make menuconfig as target Profile. Can anybody help in providing the steps to build the image for MT7628 EVB? We were able to build images for MT7628EVB using 17.01.2, 17.01.4 TAG(old commits based on 4.4.7x kernel), but not from 17.01.4 with commit ID 74a0d8c(latest) .

We want to build the latest image out of 17.01.4 (with latest commit) for MediaTek Mt7628 EVB with the latest WiFi drivers .

Thanks,
Sai

Thanks for the response Jeff.. I added the MT7628 EVB in target/linux/ramips/image/mt76x8.mk file.. after removing the tmp/ folder in source directory.. we are able to see the option in make menuconfig. Any particular reason..that the Mediatek MT7628 EVB TARGET_DEVICES has been removed in recent LEDE? i mean , something related to EVB was not ported?

It's available in the current HEAD of lede-17.01 as shown above. Perhaps you've got some differences from the upstream source.

Like said, the device MT7628 EVB is visible quite normally in 17.01 branch HEAD.
ramips / MT7628 boards / MT7628 EVB
Definition at:

But there may be a problem in the master branch, as the device's image definition is there, but the definition is missing the final TARGET_DEVICES statement:

I guess that it has just been an error in commit 3e36ca4b43 by @ldpinney . That commit combined two image .mk files into one, and it looks like the TARGET_DEVICES statement for just this one device got lost.

Some ramips specialist might look into it and check the compilation in master.
Simple fix might be:

Adding that patch (and removing tmp directory) made the device visible in menuconfig also in master.

HI Jeff, hnyman, Pinney,

    We have taken the latest LEDE master from git and able to enable/compile the image for  Mediatek MT7628 EVB . 

We followed the below steps.

git clone https://github.com/lede-project/source.git ( ramips commit to enable support for EVBis the latest )
make menuconfig ( Enable below 3 options)**
MediaTek Ralink MIPS
MT76x8 based boards
MediaTek MT7628 EVB
./scripts/feeds update -a
./scripts/feeds install -a
make

Unfortunately , the kernel failed to mount the rootfs/fail to detect the SPI flash partition and continuously rebooting.

Below are the log messages from MT7628 EVB. Please see that we are missing anything/steps to make LEDE master to run on Mt7628 EVB.

Sorry, but no help from me.
I am not a ramips specialist, but just noticed the obvious mistake in the device definition in the image Makefile.
