Re: Moving Linux kernel to 4.14

https://github.com/raspberrypi/linux/co ... f41103d422

fixed max_mtu in the function gether_setup_name(), but that one is not used: they should have fixed gether_setup_name_default()

Looks like an easy fix.

Re: Moving Linux kernel to 4.14

I have looked at the jumbo frames issue, and it was already broken in Linux 4.12. Likely due to the commit: https://github.com/raspberrypi/linux/commit/b3e3893e1253692c3d2b8e8ebd5a26183ed30443 This had unintended consequences that I in no way understand: https://github.com/raspberrypi/linux/commit/2...

Re: Security issue with the BCM43438 firmware?

The published attack only works from another device that is already connected to your network, but the RPi is at risk and the firmware should be updated.

Re: Rpi's that wont boot

If your bootcode.bin is larger than 48k, try replacing it with one of the older versions from 2016.

Re: Model A Q: Can it be USB client instead of USB host?

I don`t think the patches are in linux 4.4, but I have been using gadget mode on a model A with linux 4.9 (a prebuilt version is in firmware-next) and 'dtoverlay=dwc2,dr_mode=peripheral' added into config.txt

Re: Two Cameras and power?

The pi camera uses a lot of power, but a webcam will use more. Dave Akerman could tell you how much, but he will also tell you that you need to test it for yourself. Six batteries should be enough, but you need to leave your payload running overnight to find out. It is an easy fix to use two cameras...

Brillo has no graphics, or java, if that`s what you mean by headless.

Re: Pi 0 wifi hack postmortem

Is it really dead? Can you desolder pp1 and try powering it over usb?

My guess would be that the pp1 and pp6 wires are both touching the usb mountpoints.

Re: Maybe offical google support for Android.

This is for Brillo. It would be nice to know if it had RPI Foundation support: Google don`t always open source all their device trees.

Re: How to port libraries from ARM-7a to ARM-53

If you do want to compile for arm v7, remove this part of the code: https://github.com/intel-tbb/intel-tbb/blob/master/include/tbb/machine/gcc_armv7.h#L31 "include/tbb/machine/gcc_armv7.h" uses machine code that will only run on armv7, so the mistake in the source code is on this line: https://githu...

Re: PITS and Pi Zero Auto Start

What does it say if you type "cd ~/pits && ./build", because that seems to be failing.

Re: PITS and Pi Zero Auto Start

The good news is that you can still login, so you can install the software again.

The part that installs the tracker software is:

cd
git clone https://github.com/PiInTheSky/pits.git
cd pits
./build

that part may have failed if one of the earlier steps failed.

Re: RPi3 kernel CONFIG_VMSPLIT_3G

CONFIG_VMSPLIT is used to set the physical address of the RAM, so you have to use the "right" setting. That might be a kernel "bug" that could be fixed.

Eric Anholt is making good progress with open source hardware acceleration, and it is looking quite promising. Here is a CromiumOS build I made earlier:
