Hi,
quoted
The issue I was seeing is that there actually *is* a variant called
'RK3528' which at least according to the latest datasheets slightly 
differs
from 'RK3528A'. We are doing development based on 'RK3528A' and 
calling it
'rockchip,rk3528' which might make it hard to add the non-A-variant in
future (unless we call it 'rockchip,the-actual-rk3528').
I think this can be ignored, because rockchip only provides RK3528A 
chip.
RK3528A should be a revised version of RK3528, which solves some bugs,
so we have never seen the silk screen printed with RK3528.
Thanks for sharing that inside.
I wonder why there's an v1.4 of "Rockchip RK3528 Datasheet" dated
2024-05-12 which differs from v1.4 "Rockchip RK3528A Datasheet" dated
2025-05-12. Anyway: If everybody is happy as-is I guess it's fine.
Just for the record: There actually is a non-A version of the
RK3528, which I actually own (but forgot about - perhaps my subconscious
made me reply to this thread). It's on the Mango Pi MK28 board [0][1][2] -
which, to my knowledge, is one of the first RK3528-based SBCs.
