Running at 130MHz is unsafe since on those targets, we disable memory frequency scaling because it is unstable. That leads to situation where cpu is running at 64MHz and VDD is at 1.050V. But on STMP3700, the EMI uses the VDD rail instead of a dedicated VDDMEM rail as on STMP3780. Thus we are essentially running the EMI at 130MHz at 1.050V when the minimum recommened voltage is 1.2V. This commit runs the EMI at 64MHz all the time on the ZEN and ZEN X-Fi which will lead to reduce performance but hopefully increases stability. Change-Id: Ida6c2ec130b1778973e383d7c44a06a6ca8f9268 |
