ChibiOS Free Embedded RTOS

New generation boards: http://www.st.com/stonline/stappl/produ ... rcetype=HW

Apparently the new boards have a new ST-Link, Arduino-like connectors and new ST "standard" connectors. This means that it should be possible to make shields or motherboards usable with any Nucleo module.

Those boards are more naked than Discovery kits, no mems or other peripherals, discovery kits apparently are now positioned differently.

This looks quite interesting! Thanks for the news.

Price is VERY interesting too

See Farnell for example.

Very nice! This really seems to compete directly with the Freescale Kinetis "Freedom" boards like the popularFRDM-KL25Z. They can be had for about 13.00 USD (Digi-Key) and have on-board "OpenSDA" debugger and USB-serial converter (however these are IMO poorly implemented) and have a Arduino compatible headers. However, the Arduino headers are not provided with the board, so you have to purchase and solder them yourself which adds to the cost/effort to get up and running.

I wonder if these new boards are covered by the same evaluation license as discovery?

I just do not see the 'Legal' section on the http://www.st.com/web/catalog/tools/FM1 ... 7/PF260000 page the way is is present at http://www.st.com/web/catalog/tools/FM1 ... 2/PF252419

Maybe they have forgotten to place it there

I just got in my hands the Nucleo-F401RE.

I was confused on how you load the code with mbed... until I read that you just drag drop the ".bin" file to the drive that is created upon you connect the board... Cool!

I suppose you could use another compiler and drag and drop the bin file the same way!
Any plans for porting to Chibios?

Of course, I am waiting a new release of OpenOCD because the new STLink is not compatible with the current one.

Hi Giovanni,

ST-Link from http://www.st.com/web/en/catalog/tools/PF258168# is working from the command line:

My experience with ST-Link is better because in case of "drag&drop" flashing, VCP will not work after and it's necessary to restart the board completely.

Ciao,

https://github.com/texane/stlink - is Nucleo ready too.......

One difference seems to be that the boards come without a crystal for the main clock.
