phintegrator Posted August 11, 2016 Posted August 11, 2016 Hello All, Does someone knows a possible reason why AXP 209 on some boards are failing? That will result to an error message "Failed to set core voltage! Can't set CPU frequency". After that we cannot probe the i2c bus address of the AXP209 anymore. Hope someone can share some insights.
