==========================================================

Seems to have something to do the arm-gcc compiler.

I find the solution in this link: https://github.com/spark/firmware/issues/1054

It turned out that arm gcc 5.4 is too new for Particle Firmware.

So I did everything again using arm gcc 5.3 and it worked!!!!!!!!!!

Don't forget to change the GCC_ARM_PATH.

Particle Photon Firmware Dev Get Started Part: ARM GCC Compiler Not Found Issue

I followed this link to install my ARM GCC Toolchain:

      http://gnuarmeclipse.github.io/toolchain/install/

And I followed this link to start Photon Firmware development:

      https://github.com/spark/firmware/blob/develop/docs/gettingstarted.md

BUT I stuck at:

make clean all PLATFORM=photon -s program-dfu

And I get:

/bin/sh: 1: arm-none-eabi-gcc: not found

../build/arm-tools.mk:43: *** "ARM gcc version 4.8.4 or later required, but found ".  Stop.

This is mentioned in the Common Error and the provided solution is to export the PATH. However, at the end of the first Link above, it mentions that it would be better not to do that. So here is my solution:

(1) Locate file ../build/arm-tools.mk from firmware/modules

We can see all we need to fix is to indicate GCC_ARM_PATH

(2) At the top there is a line : include $(COMMON_BUILD)/common-tools.mk

GCC_ARM_PATH must be in there.

(3) open file ../build/common-tools.mk

We can see:

# GCC_ARM_PATH can be defined to be the path of the GCC ARM compiler,

# It must include a final slash! Default is empty

So I defined right here:

GCC_ARM_PATH = /usr/local/gcc-arm-none-eabi-5_4-2016q3/bin/

Arduino Uploading Problem: stk500_recv(): programmer is not responding

This actually works for me:
switch on verbose output during upload (in the arduino IDE preferences pane).

Delete Ubuntu Safely with Win 7

(1) Download mbrfix.zip and unzip under root c:\
http://www.sysint.no/mbrfix

(2) Open Windows terminal and input:
cd \

mbrfix /drive 0 fixmbr /yes
(3) reboot
We don't see the grub list any more.

(4) delete the ubuntu partitions.

Grub Rescue

I got this prompt when I was trying to clear out some Disk from my Win 7 for Ubuntu. Here are the commands I've used to fix the problem.

(1) Find the /boot partition
ls

we can see something like:
(hd0,1),(hd0,5),(hd0,3),(hd0,2)

(2) Try them one by one and if one shows a file "grub.cfg", that is our /boot

ls （hd0,X)/grub -- I remember I have an independent partition for /boot

(3)
grub rescue>set root=(hd0,5)
grub rescue>set prefix=(hd0,5)/grub
grub rescue>insmod normalgrub rescue>normal

We can see our grub list now. BUT!!!!!! It's not over yet.

(4) last step

sudo update-grub
sudo grub-install /dev/sda
