Mikrotik Hex S 2025 Refresh - E60iUGS - Support

Hardware Questions and Recommendations
1

I have been using the “old” hex s with openwrt in a few locations and i am generally very happy, despite the low ram & nand storage.

I was happy to see the new/refreshed hexs which would be great, but based on a post here in the forum the CPU EN7562CT is not supported on OpenWRT. I couldn’t find any explicit information if it would be somehow possible to run OpenWRT on that devices or recompile it?

Probably an issue of missing Linux support, rather than Openwrt.

You've read all the old threads mentioning EN7562CT, right ?

Thanks @frollic yes and no about searching the old threads as the outcome with e.g. MikroTik E50UG - #3 by slh pointing to the git repo is not clear for me what it means in regards of the “boardname EN7562” :frowning:

4

Source only means it's not getting built, meaning no supported devices use it.

5

sorry if I don’t get it: if the source is there, It would only need to be built? :wink: or there are other dependencies that are missing to get it compiled for that CPU?

I bought this device and I'm adding it to OpenWRT, but I'm stuck with the initramfs file which won't start:

I also had to manually edit the NOR file to enable UART on the test pins:
