SR2:VDD autocomp is not active ::: BeagleBoard Halts
Hi all, I have the following very odd observation, can anyone please elaborate on why this could be happening and possible solutions to it. When running beagleboard with android image, After running a userspace application for a while the board prints the following: SR2:VDD autocomp is not active and simply halts!!!.. Note: Smart reflex is enabled in the linux kernel... Any help would be appreciated...

Re: SR2: VDD autocomp is not active
Thank you :) , I found the "omap2_clk_init_cpufreq_table" function in the kernel image installed on my board ,and the hanging up is not permanent ,sometimes occurs and some time doesn't . So what the reason may be for this case? ..also what is the usage of "sr_vdd1_autocomp" ??

Re: SR2: VDD autocomp is not active
Basically I'm working on beagleboard rev B5 . I'm not using the pm branch of kevin ,,however I'm using source files from the rowboat project (Android) ,just I enabled the cpufreq and smartreflex in the kernel configuration while I'm building the linux kernel of Android . Any Idea :-) ??

Re: SR2: VDD autocomp is not active
Thank you for your reply , But another thing appears and also the system hangs up after activation the ondemand governor OPP4 doesn't support SmartReflex SR1: VDD autocomp not activated P.S:- I did as you told me by echo 1>sys/power/,,,etc Regards, On Mon, Dec 28, 2009 at 9:48 AM, Romit Dasgupta wrote: > > tarek attia wrote: > > Hi all, > > > > Each time I enable the ondemand governor ,it works fine for a while > > ,but each time the frequency is changed this messages appears :- > > > > SR1: VDD autocomp is not active > > > > then it works again ,but after small amount of time this messages > > appears followed by hang up for the overall system > > > > SR2: VDD autocomp is not active > > > > > > try this: > echo 1 > /sys/power/sr_vdd1_autocomp; echo 1 > /sys/power/sr_vdd2_autocomp > -- tarek -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html

SR2: VDD autocomp is not active
Hi all, Each time I enable the ondemand governor ,it works fine for a while ,but each time the frequency is changed this messages appears :- SR1: VDD autocomp is not active then it works again ,but after small amount of time this messages appears followed by hang up for the overall system SR2: VDD autocomp is not active Any one has an idea ??

Re: error message - SR1/SR2: VDD autocomp is not active
Hi, More specifically, the touchscreen controller doesn't work after it resumes. Is there any way to fix this? Otherwise my only option is to disable patches 0149, 151, 152, 153, 154, 155, 156, 157, 158, 159, & 168 onwards, generated using the command git format-patch master.

Re: SR1 / SR2 VDD autocomp is not active error & cannot suspend due to USB
Hi, I managed to get USB suspend to work after enabling the appropriate USB suspend/resume option in the kernel. Now it works fine. However, I still get the SR1 and SR2 VDD autocomp not active errors. What could the reason for this be?

SR1 / SR2 VDD autocomp is not active error & cannot suspend due to USB
Hi, I am getting the following errors when I connect a USB hub device. There are no other USB devices connected to the hub.
