Missing TH1520 SOC documentation #17

Closed AKeen12344 closed 11 months ago

AKeen12344 commented 1 year ago

There's basically no publicly available information about any part of this SOC, except maybe the GPU model used and that's not really useful either. Only real place where any parts of the SOC are documented in any detail are hidden in THead's Yocto Gitee repository.

+1 Cross-referencing from Beagle forum https://forum.beagleboard.org/t/docs-for-th1520/35860

@AKeen12344 https://lore.kernel.org/linux-riscv/ZMME6cHQzHMLUCq+@x1/#t Drew already asked to t-head about datasheet but seems takes time.

@Kreyren if you want soc chip layout then contact to beagleboard. ( I guess they opend?)

Pretty sure both of us want some more detail on hardware accelerated parts. Looking through a repo to get some level of hope of what's going on is not the greatest.

Last time I checked, both vendors were a little cagey just disclosing what GPU powers the TH1520.

(Please excuse the newbie marks)

TH1520 docs are up on https://git.beagleboard.org/beaglev-ahead/beaglev-ahead/-/tree/main/docs?ref_type=heads

Beagle were in the process of going through what they can disclose via their repo at the time the other comments talking about asking them, which kind of bugged me quite a bit for other reasons, but looks THead Semi did it themselves and Beagle mirrored it on their own repos.

This documentation is not available on the English version of THead's website as far as I can tell, and they have a login requirement to download.
