Pizero wifi crashes after a few minutes

<< < (2/2)

piran:
Although the next problem arises as a seg fault after an hour .... little steps :)

or not - it's still failing with brcmfmac_sdio errors

mocore:
possible things to try

- a powered usb hub ( to rule out power issues , perhaps cabling could also be a factor... )
     perhaps compareing usbcam power used with https://commons.wikimedia.org/wiki/Category:USB_power_meters
      a) pizero-usb
      b) pc-usb

- try asking @ https://github.com/raspberrypi/firmware/ to see what they make of the ' brcmfmac_sdio errors '  dmesg / situation

piran:
Thanks.
I've tried various different power supplies and can certainly get it to crash faster with a lower power supply.
I'll check out the firmware
I'm also going to try a different SD card just in case there's a problem there.

mocore:

fwiw , i wonder if any thing (psu,pi,sdcard,wifichip,camera)  is getting hot ?!!! 

 ... if you can cook egg's&bacon on your psu/pi/sd  perhaps the problem is  https://en.wikipedia.org/wiki/Thermal_runaway

which oddly/completely irrelevantly reminds me of Valeria Golino  ??? https://www.reddit.com/r/tipofmytongue/comments/12y2g4/tomt_movie_with_bellycooking/

piran:
Well, coming back after Christmas, doing a tce-update seems to have fixed the issue (had another issue where the camera was being very slow and would crash opencv but that turned out to be a power supply problem!).

Now to integrate it into the tactile robotic fingertip...
