Thought I'd share my idea as well: I've built a simple device from an Arduino Nano, a microSD interface and a small display as a solution to this problem. It loads the label from a text file named label.txt on the boot partition. The Arduino library I use can only read FAT32 partitions, but luckily...

AFAICT, there isn‘t any trace of an attached Ethernet adapter in any of your listings at all. It would be very helpful to mention what Ethernet adapter you‘re trying to use (maybe pictures of it), and what chipset it uses (can be found e.g. with lsusb on a computer that does recognize the adapter).

5.4 kernels seem to be affected as well: https://github.com/raspberrypi/linux/issues/3702
Haven’t tried it with a 5.4 kernel myself because my image is highly customized. Will upgrade eventually, though that doesn’t fix this particular problem as proven by the issue report on GitHub.

Any news on this issue? I'm seeing the same problem with an enc28j60 on a Pi 3A+ and already got excited when I found your thread about it. Seeing it apparently was left unresolved had me a little disappointed :roll: :D I'm seeing this trace on Raspbian Buster on a 4.19.97 kernel (the image was the ...

Are you sure you're using the micro USB port labelled 'USB' on the Pi Zero W and not the one labelled 'PWR'? Only the one labelled 'USB' can be used as an USB OTG port, the other is only for powering the Pi. This might seem obvious, but IIRC, this was the issue in a very similar thread.

Great to hear you found the culprit!

This does sound like a power issue, but it’s a bit curious you’re seeing it on a Pi Zero (W), which usually doesn’t have very high requirements on the power supply. Do you have any peripherals connected to the Pi? Did you try to use a different cable from the power supply to the Pi? Does the kernel ...

I finally found the problem, and as I was suspecting, it indeed was a stupid mistake from my part: In the kernel modules, I was registering the interrupt for the rising edge, although it should have been the falling edge. While the Raspberry Pi already started sending out data over SPI, the STM32 st...

Hi, I'm trying to write a custom kernel module for communicating with a microcontroller via SPI. Specifically, I'm now using an STM32F103C8T6 microcontroller on a cheap 'Blue Pill' type board. The Raspberry Pi is the SPI master, the STM32 is the slave. In the most basic setup, the STM32 requests an ...

Thank you for working on this. It has the potential to increase the life expectancy of Zero hardware as software is tuned to run on the ARMv7. I'm sorry I don't have any insight on the control coprocessor, but wonder, what are such instructions doing in user-space code? Thanks for the encouragement...

Any CPU upgrade to the Zero would come with an increase in power consumption.....swings and roundabouts! Interesting project, no idea if it's even possible. I agree that even this "software CPU upgrade" would increase power consumption per executed program instruction, ie there'd be a per...

I don't have the first faintest idea why you think you'd want to do this. Why not simply buy a RPi4B 4GB and you can run ARM6, ARM7 and ARM8 code natively on the processor. I have existing ARMv7 binaries (no source) that I'd like to run on a portable device with as little power as possible. The Pi ...

Hi all, I'm trying to write a kernel module that allows to run ARMv7 userspace code on an ARMv6 Raspberry Pi Zero. The kernel module registers an undefined instruction hook and parses ARMv7 instructions, manually executing the required register transfers etc. I'm hoping this would have as little ove...

Is it possible to mirror the content 90 degrees? I just merged a PR from user Steven Hickson that enables rotating the image. You now just pass the desired degree (a multiple of 90 deg) as argument to the new -r flag, e.g. ./rpiplay -r 90 So I've installed this on a Pi Zero and exactly as per the i...

Yes already discussed: https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=261725 There are only 3 variants of the Zero $ 5 Zero $10 Zero W $15 Zero WH Thanks! Sorry, seems like I missed that thread. I know of these three Pi Zero variants, meant to write build variants, i.e. different compo...

The title might sound a little misleading, so I'll clarify right away: The RAM capacity has not changed (and is technically limited by the CPU IIRC). I recently ordered a Pi Zero from Pimoroni and was a little surprised that it looked a little different than all the others I'd seen before: It seems ...

Hi, For my open source AirPlay mirroring receiver RPiPlay, I'm looking for a future-proof video and audio decoding and rendering API that Uses the video decoding hardware Supports different audio sinks such as HDMI/Analog/ALSA (DACs and USB audio interfaces) Could easily be adapted to H265 should a ...

Questions for usage: 1. How can I start the program with specific arguments -n? I can only double click the application to start?! 2. Can I change the black background to another if there is no connection? 1. You are supposed to start it from the command line. 2. Not possible at the moment, but tra...

Hi, First of all, thank you for this project, it's working beautifully! I see that it was recently changed such that a black screen appears when there is no connection. Is there a way for nothing to appear instead (so I would see whatever is running behind). In my specific case I'm running magic mi...

fd_

Hi, A few notes about your project: 1) shairport-sync is audio-only, to the best of my knowledge. For AirPlay mirroring, you'll have to use RPiPlay (an open source program I'm developing). 2) RPiPlay uses OpenMAX for decoding and rendering H264, which usually cannot be captured in screen shots. Howe...

Hi all, I'm trying to add a software-controlled power switch to a USB hub I have. The hub uses the Terminus Tech FE1.1s USB hub chip which, according to the datasheet (linked below) has "Ganged Power Control" (which I found means that all ports share a single power switch). As far as I am ...

fd_

Did you find a solution to the problem? I think I'm seeing the same issue with the Realtek 8152B, a hub (either FE2.2s (Terminus Tech FE1.1s clone) or HS8836 based) and the Zero. It must be somehow linked to the Realtek 8152B and probably some wiring issue in the hub or the ethernet adapter. To answ...

Still not seen this though I have jumped to Mojave on one but of Apple kit.

Wonder if it’s an extension clashing?

Only extension I have installed is https://apps.apple.com/app/pipifier-pip ... 4471?mt=12

The recent Safari 13.0.1 (14608.2.11.1.11) update fixed it now, so it must have somehow been related to the browser
