hm... modulemode SWCTRL causes wait_target_ready to fail. Any hints ?gets stuck in transition state. PRCM_CM_WKUP_DBGSS_CLKCTRL is always read as 0x 12510f00 which would translate into: - module disabled - all opt clocks are on - module is transitioning - module in standby - clkA as TPIU and STM trace clock - all dividers set to 2just fyi, checking with HW folks, this might be a new bug, unless debugss needs something special.
If that happens on DEBUGSS disable, it's probably the same issue as on AM33xx: http://www.spinics.net/lists/arm-kernel/msg320801.html http://www.spinics.net/lists/arm-kernel/msg321930.html http://www.spinics.net/lists/arm-kernel/msg329151.html Does adding HWMOD_INIT_NO_IDLE fix the issue you're seeing? - Paul
