I wonder the product name is x8evb or sg2042-x8evb?
The same question to x4evb.

I hope it is sg2042-x8evb.
Sophgo is also making EVB boards for sg2044.
I think a distinction needs to be made here.

Han

SG2044 evb has a formal name like srd3-10, but I think it should
have a sg2044 prefix. as the name printing on the board has a
sg2042 prefix.
But there is something needed to be checked, like whether the "x8evb"
should be "evb-1.0" and "x4evb" should be "evb-2.0".

Inochi

sg2042 prefix? :)

Agreed. To avoid confusion, it is best not to define the official
product name yourself, but to confirm with the vendor (here is sophgo)
or have them provide it, just like "srd3-10", we contacted sophgo's
marketing staff and they provided it.

Yeah, it prints SG2042_EVB_V2_0.
