sntp -s time.google.com seems to work as a clock adjuster, I'm just a bit unsure about if it keeps running or not after I've used it? It generally does the adjustment in just a few seconds. ntpd -qg is definitely a one shot that I can use each modem power up but it takes at least a quarter of a minu...

I've got Jessie on a Pi0 whose only internet connection is a 3G modem that powers up briefly every 10 mins to squirt some data to a website. I'm in all all sorts of strife with ntp, ntpd, sntp, etc. I've tried shutting down the automatic service (/etc/init.d/ntp stop) & running sntp -s google.co...

I can't seem to compile this program on a Pi0 with Jessie. Get an error 'undefined reference to `main'
collect2: error: ld returned 1 exit status' and after that the hub-ctrl.c program is gone?!

PlanB

The first fn was throwing an error saying 'subprocess referenced before assignment' but I just removed it's 'import subprocess' & it's not complaining so I'm even more confused now. Python interpreters are moody creatures.

PlanB

I import subprocess at the top of a python 2.7 program. The program calls a couple of functions that also use subprocess. The 1st fn has the line p = subprocess.Popen (['python', '/home/pi/gpioA-D/pot_cap.py'], stdout=subprocess.PIPE,stderr=subprocess.PIPE) The 2ndr uses catdata = subprocess.Popen([...

Phil, a year or so ago you were kind enough to write me a w1-gpio-intpullup.dtb file that eliminated the need for the external 4k7 on the DS18B20 data line in Wheezy by substituting the more than adequate strong internal pull up available on gpio4 I renamed the file w1-gpio-intpullup.dtbo & it w...

PlanB

I get this when I try to use the Wheezy .dtb as a .dtbo in Jessie
[ 6.517364] w1-gpio onewire@0: gpio pin 4, external pullup pin -1, parasitic power 0
[ 6.517414] w1_add_master_device: set_pullup requires write_byte or touch_bit, disabling

PlanB

Device tree puzzles me greatly but I'm making the effort. I've got a w1-gpio-intpullup-overlay.dtb file from my Wheezy days with the DS18B20 that I'd like to use with Jessie. Alas this is pushing my userland slum credentials. Anybody know how to convert this to a Jessie compatible .dtbo file?

Here is my problem as near as I can figure it out. WiFi details in Jessie are entered into /etc/wpa_supplicant/wpa_supplicant.conf The file originally looks something like; country=AU ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev update_config=1 then, when the AP details are input, it look...

I get a similar gripe when I try to use Bill Wilson's rpi-clone

For a couple of years now I've had great success with Bill Wilson's https://github.com/billw2/rpi-clone for dupicating SD cards on the pi. Great little utility that automatically resizes to fit the card your duplicating to. When I moved to jessie lite last year it still worked great. However last ni...

Having exactly the same problem here, doesn't really seem to be any of the issues mentioned in the 2013 engineer post. The fact that the keyboard/gensys combo works when connected to the pi via the TerminusTech hub just floors me, I guess because it hammers home how much I don't know about USB.

PlanB

I've got identical software (cloned sd cards) on a piA+, a pi0 & a pi3. I bought a usb hub for the pi0/piA+ but it won't work (not even with just a keyboard plugged in) on either yet identifies/functions OK on the pi3 (Bus 001 Device 004: ID 05e3:0606 Genesys Logic, Inc.

Just as a matter of interest the GPIO.add_event_detect(channel, GPIO.OPTION, callback=my_callback) version of this fn crashes the I2C bus if you happen to be using the bus at the time the interrupt occurs. If you can wait till you're not using the bus to service the interrupt then GPIO.add_event_det...

I really struggled with Jessie, all the wireless setups seemed so different. Is there no way I can get the new gpio into Wheezy?

Wow, would that all my Pi tribulations were cured so promptly, thnx

I've got a little python routine that uses wall instead of print to output diagnostics. As the program runs the diagnostics are accumulated in a log_output file & at the end the wall outputs them all at once. Wall outputs text no matter how you're connected to the pi (ssh, local terminal, 'scree...

For what it's worth the updated wheezy sd from my Pi3 works OK with the 9601 chipset, you don't have to go to jessie. The particular combined usbhub/ethernet unit I had was a dud but a 9601 based ethernet only adapter was fine.

PlanB

I'm getting no indication that there is a driver problem here, no kernel panics, the iptable looks OK, /var/log/messages are sweet. I've got this nagging suspicion something else is amiss.

PlanB

So do I have any chance of getting the 9601 chipset working without upgrading to Jessie? Jessie frightens the life out of me because of stuff like https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=110606 and this thing is looking like it should work, no kernel crashes, route -n, ifconfig e...
