Re: Seek advice on how to troubleshoot wifi lost carrier issue

+1 I'm seeing similar behavior on my RPI Zero W. The lost carrier happens several times per day, Most times it eventually reconnects buy can take 30 minutes to hours to eventually reconnect. Sometimes it will never reconnect and I have to power cycle the RPI. I've updated the firmware and disabled p...

Re: NFS over wifi

I resolved this issue although I don't understand it. I ended up executing the mount command and just letting it run over night. In the morning the mount had completed and not when I mount the NFS share it completes immediately. It works exactly as expected. So strange, but I'm happy that it now wor...

Re: NFS over wifi

Thanks I'll try the -o option.

I get no errors. It just hangs for ever. The command never completes. I can live without fstab working so right now I'm focusing on getting this to work by manually using the mount command.

NFS over wifi

I have an issue where mounting an NFS share over wifi fails. If I boot using ethernet the NFS mount works everytime. This happens mounting thru fstab and manually mounting from a terminal.

Is there something I need to do to configure the NFS client to bind over wifi??

Re: [GUIDE] Raspbian Lite with PIXEL/LXDE/XFCE/MATE/Openbox

This is an awesome post and just what I needed. One followup question. Is it possible to skip the desktop install part and just have X-Windows + GTK and run a single app, using the Pi as a kiosk running one, single GUI app? Any tips on making that scenario work?

Re: ttyAMA0 Missing

Thanks, I finally found another post that addressed this.

This issue is that when you disable the serial port for boot using raspi-config, the serial port is also disabled for ANY use.

To fix this you MUST set "enable_uart=1" in /boot/config.txt

This is really a bug in raspi-config.

ttyAMA0 Missing

I had to reinstall my Pi because the SD card went bad so I used the lasted version: jessie from 5/27. I need to use the serial port for my code so I used raspi-config to disable boot from using the port, just like I've always done. Problem is that the /dev/ttyAMA0 is missing. I also disabled the ser...

Re: Building 3.18 Kernel

More than likely yes. So where can I get the sources that match the current Wheezy image?

Re: Building 3.18 Kernel

Yea, I'm aware of the config differences. I've built using "bcm2709_defconfig" to generate the .config file and I've tried building using a .config file that I created using "zcat /proc/config.gz > .config" to capture the RPI2 configuration. Neither way works properly.

Re: Building 3.18 Kernel

Thanks for the reply. What you're saying makes sense, but there must be a way to get the same sources that the Wheezy image was built from. I got the sources from "git clone --depth=1 https://github.com/raspberrypi/linux". The default branch is 3.18.y. The version from the RPI2 via uname is "3.18.7-...

Re: Building 3.18 Kernel

I'm not concerned with how fact the compile process is right now, just with getting it working. So unless the linaro gcc will somehow do that I don't think I need to change compilers.

Re: Building 3.18 Kernel

I am copying just the compiled kernel module. I do not want or need to replace the entire kernel.

Re: Building 3.18 Kernel

Also, just to verify the problem I replaced the snd.ko kernel module that I built and got the same result. No kernel modules that I build are loadable and all get the "disagrees about version of symbol module_layout" error message.

Re: Building 3.18 Kernel

The i2c_bcm2708 is not an overlay but a loaded kernel module. lsmod shows the module as loaded in normal operation. I used the option in raspi-config to enable I2C and am aware of that. The linux/drivers/i2c/busses directory does in fact build a i2c-bcm2708.ko file and on a RPI2 system there is /lib...

Building 3.18 Kernel

I am trying to build the kernel for a PI2 that is running 3.18.7-v7+ kernel. My goal is to rebuild the i2c-bcm2708.ko kernel module. I've successfully built everything but the module will not load. I get the message "disagrees about version of symbol module_layout". The Module.symvers seems right an...
