Hi Tero,
Thanks for the reply. I'll try this out. I don't think mpu_opps is defined for my board_overo.c file. I guess I should look at the board_sdp3430.c as an example for this?

Thanks and do let me know!

Best regards,

Elvis

Hi Elvis,

I think I saw something similar last week, and it was caused by not having CONFIG_OMAP_PM_SRF enabled. The actual culprit is the marked line in sr_configure_vp():

               vpconfig = PRM_VP1_CONFIG_ERROROFFSET |
                       PRM_VP1_CONFIG_ERRORGAIN |
                       PRM_VP1_CONFIG_TIMEOUTEN |
mpu_opps[resource_get_level("vdd1_opp")].vsel <<
                       OMAP3430_INITVOLTAGE_SHIFT;

SR2 has similar code a bit later.

You will also get a failure if mpu_opps[] and/or l3_opps[] is not defined at all in your board files, this null pointer exception would actually indicate a problem like that more likely.
