Look at the package of SoC chip. On top of the package is printed identifier 88F3720. On the last line should be one of the string: C080, C100, C120, I080, I100 which identifies frequency (080 = 800 MHz, 100 = 1 GHz, 120 = 1.2 GHz) Can you check what is printed on A3720 SoC package? > BTW, with the 1200_750 firmware and the patches: > > root@OpenWrt:/sys/devices/system/cpu/cpufreq/policy0# cat > scaling_available_frequencies > 200000 300000 600000 1200000 > > Of course that could mean nothing, but thought I'd mention what I do see. This is value set by firmware file which you have started.
