You can add kernel boot parameter editing the file /etc/default/grub:
$ sudo vi /etc/default/grub
Just add it to variable:
GRUB_CMDLINE_LINUX_DEFAULT
Then just update GRUB:
$ sudo update-grub

I was using the default “gcc-arm-none-eabi” package from Ubuntu 14.04 but was receiving this error message when trying to compile “nrf51-sdk”:
arm-none-eabi-gcc: error: nano.specs: No such file or directory make: *** [blink.elf] Error 1
Searching about the issue I discovered this issue is related to Ubuntu’s gcc-arm-none-eabi package, more info see:
https://bugs.launchpad.net/gcc-arm-embedded/+bug/1309060
Then I followed the steps suggested:
$ sudo apt-get remove binutils-arm-none-eabi gcc-arm-none-eabi $ sudo add-apt-repository ppa:terry.guo/gcc-arm-embedded $ sudo apt-get update $ sudo apt-get install gcc-arm-none-eabi
Now compilation goes fine!
These are the steps I’m executing to try to compile the nrf51-sdk on Linux:
$ git clone https://github.com/relayr/nrf51-sdk.git $ cd nrf51-sdk $ mv build.mk Makefile $ cd nordic/ $ unzip ../../SDK/V8/nRF51_SDK_8.1.0_b6ed55f.zip (download from https://developer.nordicsemi.com/nRF51_SDK/) $ cd .. $ vi nordic/components/drivers_nrf/pstorage/pstorage.h replace the include to: #include "config/pstorage_platform.h" $ make arm-none-eabi-gcc -MM

NuttX is fantastic, just like Linux is… except you cannot run Linux in a fast way in small microcontroller.
From NuttX shell (NSH) I could test if MPU-9250 is working, just reading the WHOAMI (0x75) register:
nsh> i2c get -a 68 -r 75 READ Bus: 1 Addr: 68 Subaddr: 75 Value: 71
NuttX is wonderful!!! (Kudos to Gregory Nutt)
These are the commands I use to flash a nuttx.bin firmware in the STM32F407 microcontroller:

I was trying to get fastboot working with my low cost Dell Venue 7 but the fastboot doesn’t return anything.
After some search I found this fastboot binary:
http://www.mediafire.com/download/pbr4b2x2ig9b2m5/fastboot
I found a reference to it here:
https://software.intel.com/en-us/forums/android-applications-on-intel-architecture/topic/494961
Magically it worked fine!
I was getting this error message trying to compile an Android application using the gradle :
* What went wrong: Execution failed for task ':app:preBuild'. > failed to find Build Tools revision 21.1.2
This error means there is not android 21.1.2 support on my SDK.
I can list all available versions and install it this way:
$ android list sdk -a Packages available for installation or update: 156 1- Android SDK Tools, revision 24.4 2- Android SDK Platform-tools, revision 23.0.1 3- Android SDK Platform-tools, revision 23.1 rc1 4- Android SDK Build-tools, revision 23.0.1 5- Android SDK Build-tools, revision 23 (Obsolete) 6- Android SDK Build-tools, revision 22.0.1 7- Android SDK Build-tools, revision 22 (Obsolete) 8- Android SDK Build-tools, revision 21.1.2 9- Android SDK Build-tools, revision 21.1.1 (Obsolete) 10- Android SDK Build-tools, revision 21.1 (Obsolete) $ android update sdk -a -u -t 8
