Hi Laurent, Thanks for V2, it is looking better and better. Great that r8a7791 and r8a7790 can share the CPG code. I have now finally got my r8a7791 board replaced so I intend to try your code out on Lager and then see if I can cook something up on Koelsch. I have one question related to the CPG. What is your plan regarding CPU Frequency scaling? I'd like to see "z_clk" and "z2_clk" implemented together with some way to let CPUFreq scale "z_clk". Can you please spend some time on that?
