Hi,
Almost finished product. DM8148 with IPNC RDK 3.8 as basecode.
Question:
Due to an awful amount of overheating problems (from flash corruption to PHY stalling), I need to substantially lower the DSP Clock.
I've followed this post https://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/716/t/229933
And changed DSP_M from 500 to 100, 250 and 400. Only the defult 500 worked. All the others caused the system to stall right after the 'boot' comand on U-boot.
I do not want to turn off the DSP core, just to lower its clock as much as possible. I've also set the core voltage to ~1.16V, to match OPP100 recomendation.
Where else must I change to achieve lower DSP clock speeds? What's the trick?
