Please advise. > 6.12 is the latest LTS supported by evl, so yes, this may be a good choice in your case. The grub installation issues you are seeing are not related to evl which has no influence on the aspects you mentioned, you would have the same with a plain stock linux kernel. You may want to refer to other online resources explaining how to build and install a mainline kernel in place of the one shipped by your linux distro. In the early stage of bringing up your target system, you may want to disable CONFIG_EVL, CONFIG_DOVETAIL and CONFIG_IRQ_PIPELINE options in your Kconfig, until you get a v6.12 kernel properly booting your box, in order to rule out any issue with evl. Once this kernel boots with a working console in order to get the information you need to progress, then you could enable these options back one by one in reverse order, discussing on this mailing list any issue observed while doing so. -- Philippe.
