Seems last patents expired 2 weeks ago! https://www.theregister.co.uk/2018/02/1 ... g2_patent/

AndyPi

Is it possible that you need to add the g_ether modules into the initramfs and load the modules on kernel cmdline
maybe something like

Code: Select all

MODULES="dwc2 g_ether usb_f_ecm"

in the initramfs config file

AndyPi

Have a look at

Its possible I think to convert images in to GL textures which can then be processed with shaders. egl_image = eglCreateImageKHR(eglFS->display, EGL_NO_CONTEXT, EGL_IMAGE_BRCM_MULTIMEDIA_Y, (EGLClientBuffer)buf->data, NULL); if (egl_image == EGL_NO_IMAGE_KHR) Error("No egl image created",0...

Hi, I am trying with zero too and get a long wait. Did your revised bootcode fix ? andrew@andrew-desktop:~$ sudo ./usbboot/rpiboot -d zero/boot -v Waiting for BCM2835/6/7 Found device 1 idVendor=0x0a5c idProduct=0x2763 Device located successfully Initialised device correctly Found serial number 0 Se...

ncurses supports mouse operations seehttp://www.tldp.org/HOWTO/NCURSES-Progr ... mouse.html. Alternatively you can read the mouse device /dev/input/mice

AndyPi

Have you looked in the build.log ?
also ct-ng list-samples lists some custom rpi samples configs
take a look at http://www.bootc.net/archives/2012/05/2 ... pberry-pi/ and http://crosstool-ng.org/#download_and_usage

I am mildly irritated by all the cfg80211 messages at boot and set about seeing if I could reduce them. I have a Pi3 and have uncommented the GB entry in /etc/conf.d/wireless-regdom. I find that when I do iw reg get global country GB: DFS-ETSI (2402 - 2482 @ 40), (N/A, 20), (N/A) (5170 - 5250 @ 80),...

Take a look at https://github.com/raspberrypi/tools/tr ... er/usbboot and https://github.com/raspberrypi/tools/issues.

Upshot is (I think) that it needs some attention and will get some eventually

AndyPi

All good in Arch 4.1.19-3

PS add

ExecUpPost='iw dev wlan0 set power_save off'

to netctl profile to disable the bothersome power management

AndyPi

Got a Pi3. Install latest raspian. switch on, it boots OK. Get wireless working as well...so far so good. Switched HDMI cable to another Pi (B2) when I switched back I get no signal. Switch cable back to Pi2 and signal returns. I am able to SSH into Pi3 when there is no signal so definitely booted b...

For completeness: Pi2 dmesg fragments CPU: ARMv7 Processor [410fc075] revision 5 (ARMv7), cr=10c5387d [ 0.000000] CPU: PIPT / VIPT nonaliasing data cache, VIPT aliasing instruction cache [ 0.000000] Machine model: Raspberry Pi 2 Model B Rev 1.1 and Kernel command line: dma.dmachans=0x7f35 bcm2708_fb...

AndyPi

On my updated Pi2 image it also has

bcm2710-rpi-3-b.dtb

in /boot so at least it knows about it. I seem to recall that the boot messages properly identified the Pi3.

AndyPi

Arch Arm site indicates that for now Pi3 is to use Pi2 software https://archlinuxarm.org/platforms/armv8/broadcom/raspberry-pi-3 I assume that taking a fully updated Pi2 card and plugging into Pi3 is equivalent to doing a fresh install (?). However although Pi3 + Pi2 card boots OK it seems to boot a...

Hi I did the adafruit tutorial on gadget mode. When it comes to internet sharing they do it on a macOS. To manage it on Ubuntu as host I did the following (BTW I don't really understand what I'm doing but it seems to work. Need to use ip forwarding which is controlled via a sysctl value. To view sys...

Tried three cables. A short one (250mm) from Chromecast kit (I think), one from TomTom kit, one from newish Motorola smart phone. All give same results.

AndyPi

I have a couple of cables with male micro A / male USB-A. Not sure where they came from, do I need something extra special. As I said the Pi0 seems to enumerate when connected using this cable and am able to send usbbootcode.bin OK and read response, just doesn't want to re-enumerate after the bootc...

I must be doing something wrong! Got my Pi zero and want to experiment with the usb device mode. I am having trouble with the simple use of rpiboot. I have compiled and installed the rpiboot program on Ubuntu 14.10 PC. Got a pi zero with empty sd slot, usb micro to USB A cable connected to USB slot....

I have RPI2 and been using Edimax AC600 ( ID 7392:a812 Edimax Technology Co., Ltd )for some time without much difficulty. I am using Arch currently at 4.1.15.
