Fwd: 96boards: automating USB OTG unplugging

by Amit Kucheria

Hi all, Several people have complained about the need to constantly connect/disconnect usb cables when switching from image flashing (over OTG) to booting with usb-ethernet/keyboard/mouse (on the Type A connector) on the currently available boards. Since LAVA has automated this, I got Tyler to do a short write up (Thanks!), added a diagram and here it is[1]. This should alleviate some of the pain. Please feel free to share externally with others who've been asking for how to do this. Regards, Amit [1] https://docs.google.com/document/d/1tCbC7gCRAIvmqXkePqMK-fLL0jfE3EPk3zW_u9x…

fail to dump value from coprocessor in ARMv8 by openocd

by Haojian Zhuang

Hi Philip & Peter, I found there's the limitation on dumping coprocessor value on armv8. My platform is hikey. I found there're "hi6220.cpu" and "arm" commands in openocd. But I failed to dump any coprocessor value by these commands. After checking the sourcecode, I found that they're just used to dump ARMv4 -- ARMv7. And there's no really support in ARMv8 to dump coprocessor. Do you plan to enable this feature on ARMv8? Best Regards Haojian

Re: [Dev] Draft 96Boards Sensors Kit Getting Started Guide

by Lee Jones

> Also, can you please let me know if your board was missing the > bootloader, and if you were able to get it reflashed? The Sensor Board delivered to me was also wanting of a bootloader. The initial plan was to flash it with a USBAsp bought from China, however the Arduino IDE complained of a programmer error and refused to load the binary. Assuming the problem was related to Dan et. al's low Current issue, I moved right along to the 'Arduino as ISP' method using one of my Nanos. http://tinyurl.com/nanoasisp In the attempt depicted above, the Nano is connected to the Sensor Board via the ISP header and power is being drawn from the Nano's v5 supply; however, during subsequent attempts the Uno headers were used and despite testing all configurations both with and without external power from a regulated power supply, all attempts to flash using 'Arduino as ISP' sadly failed with a 'not in sync' error. After a little Googling I stumbled across and interesting article which mentioned that all of the cloned USBAsps are shipped with ancient firmware which requires updating. Unfortunately after removing the device from its case it was evident that the 'self programming mode' jumper/button had been omitted on my version. I traced the Reset line from the AVR and back from the Reset pin on the header and discovered that it's possible to bridge 2 of the vias which had the desired effect. Flashing the USBAsp using the Nano in 'Arduino as ISP' mode was successful. http://tinyurl.com/usbasupdate Wiring the newly updated USBAsp up via the Sensor Board's ISP port finally did the trick. After which it was possible to program the AVR from HiKey. http://tinyurl.com/usbaspsensorboard It's just I2C support which is now lacking.

UART adapter documentation and design files

by Grant Likely

For those of you who have a 96Boards UART adapter board (Sonic Screwdriver), I've written a user guide and the design files are available on the Linaro git tree. https://docs.google.com/document/d/1x3g4mfZJ2GxHCUYXp_O-ShwlbhJE2bMRtjcyRPF… https://git.linaro.org/people/grant.likely/96boards-uart.git g.

bluetoothctl hangs

by Milosz Wasilewski

Hi, I'm playing with BT devices using bluetoothctl. When I connect some HID (mouse, keyboard) bluetoothctl hangs and doesn't accept any commands. The sequence looks like this: trust <mac> pair <mac> connect <mac> --> hangs here Is this expected? I'm able to put bluetoothctl to background and the devices are still connected. milosz

AndroidFastbootApp.efi

by Milosz Wasilewski

Hi, What is the purpose of publishing the AndroidFastbootApp.efi together with other UEFI binaries? http://builds.96boards.org/snapshots/hikey/linaro/uefi/latest/ The flashing instructions don't mention it in any way. Is there a way to update only the AndroidFastbootApp.efi without changing fip.bin? milosz

HiKey AOSP #184: OpenGLRenderer 'Out of memory' errors and corrupt display

by Jerome Forissier

Hi, I am trying AOSP snapshot 184 [1] + UEFI snapshot 75 [2] on my HiKey board, and I'm seeing some corruption on the HDMI display [3]. OpenGLRenderer logs some 'Out of memory' errors. Am I doing something wrong? Is this a known issue? (I found nothing in the bug tracker [4]). I have posted the outputs of 'adbg logcat' [5] and 'adbg shell dmesg' [6], taken shortly after a clean boot.

FTP support on BT with Linux build

by Milosz Wasilewski

Hi, Is FTP supported on bluetooth using Linux/Debian on HiKey? Chase (CCed) said he was able to transfer files using Android build on HiKey. From what I can see, the only supported profile on Linux is a2dp. milosz
