Ok, found the answer here:




H2+ is a variant of H3, targeted at low-end OTT boxes, which lacks Gigabit MAC and 4K HDMI output support.

H3 images are proven to run on H2+.

According to the source code of BSP[1], variants differ by the last byte of the first word of SID. 0x42 and 0x83 indicates H2+, 0x00 and 0x81 indicates H3, and 0x58 indicates H3D (a still unknown variant).



Mine has "H2+" labeled on the CPU chip.


Ok, case solved.
