Re: Call for beta testers: FIQ_FSM USB driver rewrite

Thanks GrayShade for the link. I understand a bit more now. As an engineer, things bother me when unexplained! Not that I lost sleep over it, but a significant change in a value is a thing of concern, at an order of magnitude! :) I did notice a significant drop in IRQ after the firmware change on my...

Re: Call for beta testers: FIQ_FSM USB driver rewrite

I notice that the April 28 Firmware update for FIQ FSM causes quiescent CPU ( no load) to increase by an order of magnitude. Reverting to pre April 28 firmware "fixes the problem". Before update the CPU average reported as 0.2 to 0.4%. After update it is reported as 3-4%. the data comes from here: V...

Re: SD Card Corruption

Basically by doing that you are telling the card that all sectors (blocks?) are now full of data. Which happens to be all zeros. The SD cards controller now cannot use those blocks to perform any wear levelling it may want to do. Heater, thanks, maybe that is what happens, the writing everywhere sl...

silly question, maybe, but could the grey blocks be caused by an operating system issue like incomplete write to disk (i.e. if sync is used it would not occur as cached data write is forced by sync) and the other process grabs it before the O/S has completed its "housekeeping" lateral thinking maybe...

Re: Static and Sensor modules

I certainly wasn't aware of any static discharge, nor have I ever noticed any while at my desk. I'd imagine the amount it takes to destroy a static sensitive chip would be way below the threshold of human perception.

Pi quits Graspberry have you added a line to /boot/config.txt. On mine, it boots into safe mode without this line though.
