Using the Cortex M0 cores?

Ooops sorry for the first message!

I’m doing some bare metal coding on the Rock960 and would like to use the PERILPM0 core on the Cortex-M0. To do that I would need to remap its memory. The Rockchip TRM for the RK3399, in section 7 has some tables describing how to remap memory. The problem is the tables reference GRF registers for which there is no documentation. For example, in Table 7.2 it calls out [31:28]: sgrf_perilp_m0_con7[3:0] and [27:12]: sgrf_perilp_m0_con3[15:0] for use to remap memory starting at 0x0. But nowhere in either part 1 or part 2 of the TRM are the registers sgrf_perilp_m0_con3 or sgrf_perilp_mo_con7 locations defined.

Any ideas on where to find data relating to these registers?

Thanks

Hi @Bob_Stewart

Sorry, we never had any info on using the PERILPM0 M0 core of rk3399. Since it is not Rock960 specific, I think you should contact Rockchip directly. AFAIK, they never released any open reference sdk for that core.

Thanks,
Mani

Thanks for the info, Mani. I’ll try Rockchip directly.
