How to make ESPRESSObin v7 stable?

Recommended Posts

It looks like that even with latest patches is 1.2 GHz mode unstable on more boards. Therefore there is a proposed patch which completely disables cpufreq driver on 1.2 GHz variant of all A3720 SoC including Espressobin:

If you have any input on this or reaction from Marvell / GlobalScale, please reply.

Thats sad. Another Marvell SoC which has dvfs advertised but not working. We went through similar troubles with A380 (Helios4 and Clearfog), seems like there is not much interest from chipmaker to help out.
