building micropython for STM32F7DISC and Nucleo_F767 gives this error message. Please help.....

Are you using the arm toolchain from here: https://launchpad.net/gcc-arm-embedded

It looks like your toolchain is too old to have m7 support.

I am using Raspberry pi 2 as a linux platform. I am newbee on micropython build. Will you please help me by command codes, how to setup latest version of gcc-arm-none-eabi on my raspberry pi. i am very much interested on micropython. I have tried this command

"sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa"

but it gives me a error message :
pi@raspberrypi:~ $ "sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa"
-bash: sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa: No such file or directory

Because you don't mention otherwise, I'm assuming you're running the Raspian distro on your Raspi. Adding PPAs with add-apt-repository AFAIK only works on Ubuntu-based systems, which Raspian is not.

Anyway, if you're trying to build MicroPython to run on your raspi, you don't need the gcc toolchain for bare bones ARM system, you need the normal GCC and build tools for the Raspi.

If you're trying to build the MicroPython firmware for the Pyboard, install gcc-arm-none-eabi package from the standard Raspian package repository, then follow the instructions in the README in the "stmhal" directory.

I'm not sure where you would find a raspberry pi version of the toolchain which includes M7 support.

gcc-arm-none-eabi package from the standard Raspian package repository does not support M7 device. Here is the details

Package: gcc-arm-none-eabi (4.8.4-1+11-1)
GCC cross compiler for ARM Cortex-A/R/M processors
Bare metal compiler for embedded ARM chips using Cortex-M0/M0+/M3/M4, Cortex-R4/R5/R7 and Cortex-A* processors.

need help . what to do??

Maybe try the approach described here: https://www.raspberrypi.org/forums/view ... 29&t=99127

Or try Arch Linux instead of Raspian?

for building STM32F7 Discovery i have used Raspberry Pi 2 and these are the command line codes.

Step1: sudo apt-get install git
Step2: sudo apt-get install gcc-arm-none-eabi
Step3: sudo apt-get install screen
Step4: git clone https://github.com/micropython/micropython.git
Step5: cd micropython/stmhal
Step6: make BOARD=STM32F7DISC

But its works for STM32F4 series only. Not works for STM32F7 series. Experts of micropython please help me on for building micropython for STM32F7DISC or NUCLEO_F767ZI.

You'll need to find a distro for the Raspberry Pi that has an arm cross compiler that supports M7, or build one yourself. I've never built a toolchain on the raspberry pi, so I don't know if it even has enough RAM to support that.

Those are basically your only options if you want to use the Raspberry Pi as a host.

The title of this thread says "on windows". The launchpad site includes a gcc toolchain for windows which includes M7 support
