I'm having problems on a brand new Zero, I prepared the SD on a Zero W to install updates and other via internet, I disabled bluetooth and I left wifi enebled in case I'll need to change something on the SD using the Zero W headless.

on the Zero W all works like a charm but when I move the SD on the Zero it freezes.

so:

1 ) are the Zero and Zero W software compatible?

2 ) or do I need to disable both blueetooth and wifi to make it work on the Zero?

3 ) or maybe my Zero is faulty?

4 ) otherwhise how can I set up a Zero without internet connection, download updates from another computer and then move them to the Zero using an USB stick would be annoying


UPDATE

I formatted the SD card using SD Card Formatter then I wrote on it the 2019-04-08-raspbian-stretch-lite image, I changed config.txt and cmdline.txt as described here for gadget mode, when I booted the 1st time it got stuck on:

after 5min it rebooted and then got stucked on:

after 2min it rebooted and then got stucked on:

touching it I almost burned myself for how hot it was, definitely faulty?

  • 1) yes, except for wifi/bt 2) yes 3) don't know 4) use gadget mode – Jaromanda X Jul 8 at 23:58
  • so do you think the cause of freezes could be the wifi enabled? – Miky Jul 9 at 0:25
  • not sure to be honest – Jaromanda X Jul 9 at 0:44

If the OS loads correctly but randomly freezes, there might be something wrong with the RPi, but if the boot process gets interrupted, or paused for a very long time without letting you login it most likely means the DHCP server is trying to find the interface in which your Pi was set and thus you may need to boot again on the other Pi and disable wifi, or create a new image using this Pi Zero.

  • I have the boot option wait for network disabled, so it shouldn't be a problem – Miky Jul 9 at 6:23
  • I added to /boot/config.txt dtoverlay=pi3-disable-bt and dtoverlay=pi3-disable-wifi but still freezes, a faulty Pi? – Miky Jul 9 at 21:42
  • If you added the wifi settings on your pi manually, it might want to do the network first... try leaving it until it asks you to login or until it actually fully boots. wait up to maybe 20 minutes... if nothing then I would say try a different image. – Agustin Jul 10 at 2:45
  • If you don't have a second sd card you can backup this one unto a .iso in mac or .img in linux and reformat it and start over knowing you haven't lost your work on the previous image. See here for instructions: thepihut.com/blogs/raspberry-pi-tutorials/… – Agustin Jul 10 at 3:09
  • currently I can login, it freezes when I run my python script that captures images to a USB stick, which on the Zero W works. also I tried on the Zero another SD (always prepared on the Zero W) and it freezes when running scripts or browsing directories. so probably a faulty Pi? – Miky Jul 10 at 11:15
