First of all thank you for your shown interest in meta-resin and devices support. Sorry for the confusion related to yocto version “fido”. Yocto releases twice per year and you can see here the ones that were already done and the next to be released. Our current yocto layers are developed for the fido version which means that all the dependencies of these layers need (or is recommended) to be based on fido (obviously, this includes poky itself).
In order to add resin support for a board, the first step is to search or develop a BSP layer. Generally a BSP layer includes kernel, bootloader, gl libraries, all being specific for that board. I searched the internet and the yocto support for the ISEE IGEP board seems to be already done but only for older releases of yocto (see here) which means there could be some time needed to be invested in order to make it work with out code or upgrade it to yocto fido.
The above mentioned support is not officially recorded as yocto layer (oe layers) so this means that is either work in progress or is just not known to yocto community (oe).
As soon as you get through these basic requirements, following the document should get you to a new supported board. Be aware though that this document is still in early beta stages so feel free to ask questions and we will support you through this new board adoption process as much as we can.
