@mirzak
I have tried the same for FireFly-RK3288 ([http://en.t-firefly.com/product/rk3288](http://en.t-firefly.com/product/rk3288)). This Board is similar to Asus Tinker Board. But it has emmc so I have tried to flash gptimg thru otg. But the U-Boot got hangs in “Loading Environment from MMC”
Can u please help to port it to FireFly-RK3288 eMMC . Please let know what are the parameter has to be changed.
I have change MACHINE = firefly-rk3288 in local.conf
and added MENDER\_FEATURES\_ENABLE\_append = " mender-image-gpt"
Thanks

Hi @karthi welcome to Mender Hub.
I’m not terribly surprised that it has issues in U-Boot. That is generally very board-dependent and the U-Boot fro the Tinker board is unlikely to work on the FireFly board. There does appear to be a _firefly-rk3288\_defconfig_ in the upstream U-Boot sources so this likely can be made to work but you will need to build a custom U-Boot and integrated it into mender-convert.

Hi @karthi,
The details are here: [https://docs.mender.io/2.3/devices/yocto-project](https://docs.mender.io/2.3/devices/yocto-project)
It’s probably easiest in your case to start with the Tinker board configuration as documented on this page but swap out the MACHINE definition. From there just run a build and see what happens. It’s hard to say up front where the changes are going to be.

Hi @drewmoseley
I have build image using [https://github.com/mendersoftware/meta-mender-community/tree/thud](https://github.com/mendersoftware/meta-mender-community/tree/thud) for SD card with a small patch for firefly-3288

I guess it’s just a matter of following the manufacturers instructions at this point. It sounds like you have made good progress. I did find the following which may help:
