{tabbedtable} Tab LabelTab Content

The Raspberry Pi 3 Model A+ is the latest product in the Raspberry Pi 3 range. Like the Raspberry Pi 3 Model B+, it boasts a 64-bit quad core processor running at 1.4 GHz, dual-band 2.4 GHz and 5 GHz wireless LAN, and Bluetooth 4.2/BLE. The dual-band wireless LAN comes with modular compliance certification, allowing the board to be designed into end products with significantly reduced wireless LAN compliance testing, improving both cost and time to market. The Raspberry Pi 3 Model A+ has the same mechanical footprint as the Raspberry Pi 1 Model A+.

Comment List
  • I worked for a company that used Raspberry Pi in their fingerprint reader as a communication controller and Pi's display to provide visual feedback.

    Also I know cases where Pi is used to capture photos for site's time lapse.

  • Hi Aswin,


    This is an old issue (almost a year old). The recent kernel version is at least 4.19.x, so it is likely to be a different issue I think. (Not sure though).

    @robogary, do you have the information regarding the disk space (df -k). If you can print it out in its entirety, that will be helpful, or if you can confirm the previous storage space issue is resolved.

    If there's limited space for swapping, then you may get strange memory allocation issues (I'm speculating - I've not been in this situation -

    I've had no issue compiling OpenCV on a Pi 3B in the past). What brand micro SD card are you using, and where was it purchased from (this could be relevant).

  • Thank you. You have taught me a new place to look for known bugs. I appreciate your kind help.

  • This is a Linux Kernel issue. It consistently occur on current 4.14.6x and 4.18.x pi kernels after varying intervals.


  • Hi Gary,


    Generally the microSD card shouldn't be swapped from one Pi to another. Once it is running, a separate microSD card should be used for the other Pi. Otherwise you're just making life difficult for yourself, having to debug one thing on top of another.

    Regarding the message, is this related to the low storage memory you had (I think you mentioned a 16GB card was insufficient). Is that resolved now?

    It is worth checking with df -k

    Could you display the entire output from that command?

    Also, there's no need for NOOBs, Raspbian can be downloaded and used. Incidentally have you noticed the vague wording on the raspberrypi.org website, where they suggest to download Raspbian, but then put the icon/link to NOOBs first : ) I often notice subtle "usability" type issues like this : )

    I wonder how many people go through hoops to install Raspbian via NOOBs as a result of this..



  • The Raspberry Pi 3A is having an issue compiling openCV. I reboot, make some more compilation progress, but the compilation process never completes.

    When the SD card is installed into a Raspberry Pi 3B from Raspberry PI A, this same error message is seen, and both 3A and 3B lock up during compilation.

    ( process stops updating, the Pi green LED is solid on, the real time clock on Pi splash screen stops incrementing) I dont recall seeing this message with a 16Gb uSD card, and I dont recall seeing it the first time the 32Gb uSD card was used.

    After opencv locks up the PI, I have reformatted the uSD card using full format and quick format of the SD card formatting tool, and reloaded NOOBs 3.1.1 a couple times (very time consuming) and restarted the whole compilation process and wonder if this message is relating to my compilation problems.


    Any suggestions on root cause and corrective actions ?


    I tried with both 16Gb uSD card and 32Gb uSD card, and get same error in 2 different Pis, and desktops seem to work so it likely isnt the root cause of my openCV compilation problems, and I may be chasing my tail.

  • As I alluded, system sizing was a task I was familiar with in past careers. I have had a few gotchas over the years that have caused consternation in projects. Always interested when someone has a similar experience.  Thanks for sharing.



  • I recall reading something that suggested testing and approval was done for of SD card size 16G. I can't find the link. I use a number of vendor 32G cards but never expanded the O/S to take full advantage. I did find this link https://elinux.org/RPi_SD_cards  examining SD cards and Raspberry Pi. Not sure if helps.



  • Thank you for insights. I checked card space with df -h , sure enough it was full. :-)  The configuration menu said the program space already at maximum by noobs.  The program I was installing annunciated that it stopped due to lack of space. The installation instructions warned the application was pretty big, and it might be a good idea to delete Libre Office to save space. I appreciate your suggestions. It  is an adventure when trying a new unfamiliar and challenging project in Raspberry Pi.

    The 32 Gb uSD card wasnt anymore expensive than a 16Gb or 8Gb, maybe even less cost.

    I also use alot of WTV020SD-16p sound modules , they are limited to 1Gb maximum uSD card. DFplayer modules can allow larger uSD cards, I just want to keep my hobby parts inventory as common as possible between different modules and platforms.   

    32 Gb is my new standard for Raspberry Pis. .....at least for now  :-)

  • Hi Gary,


    Is it possible the file system has not been expanded? By default, it is a small value (2GB) but needs expanding using the raspi-config program.

    Maybe you've already done that. I don't know what applications you've installed, so it could be normal, but I figured I'd mention it just in case.

    Also there are various commands that could help, maybe 'df -k' will reveal enough.
