Head Weblink the manufacturer of HDRM200 have released a different variant of HDRM200, with an MT7621 CPU instead of MT7620A. After corresponding with them they have confirmed this change. Could do with adding a comment on the hardwaredata page to reflect that (or maybe it needs a new page altogether). I would do this but I don't have an account for this.
They still call it HDRM200 which is annoying, the only visible difference is the PCB is labelled
It's likely the bootloader is also slightly different to reflect the different CPU.
In terms of OpenWRT support, the MT7621 EVB target kernel image boots successfully from TFTP, but it does not detect the mtd partitions, presumably because the generic dtsi file does not have the specific partition definitions. When writing the sysupgrade image to flash it does not boot at all, probably for the same reason.

ok I will do that now. after I have done that - would it be best to add a comment about this new variant on the HDRM200 page, or create a new page and call it HDRM200 rev2 or something?
There's no point in adding a new device page until it's supported, IMHO.
Put a comment/warning high up on the current page, regarding the new version currently not being supported.
thanks @tmomas - I'm not actually sure what I would call the devicepage if I made a new one as there isn't an official name for HDRM200 rev 2 - maybe I'll just add a comment to the existing page for now?
I have added a link to this topic now to the dataentry page.
Since there was no devicepage available yet for the HDRM200, I have created one now (only the skeleton, needs to be filled in by users). -> https://openwrt.org/toh/head_weblink/hdrm200
This would be the place to make clear that there are two variants out there, one with MT7620A, another one with MT7621.
