MicroPython on i.MX6

Postby Tetraeder » Wed Nov 18, 2015 2:36 pm

Hi,

after many attempts I’ve managed to port minimal to i.MX6 quadcore :mrgreen: .
I get a repl via UART.
I report the next day about the progress.

Do you mean you run it bare-metal, without Linux? If so, that's indeed pretty cool, details wanted.

Yes as bare-metal. On a Freescale Sabre board.
My tests so far: variable declarations and small calculations(10*5).

Something is not right with UART: it will not appear to me that I typed in but after I hit enter, it is displayed.

Cute. If you'd select more wide-spread target, like Raspberry Pi, or just bare-metal x86, you might even catch some people testing or even contributing to it. Otherwise, well, keep us posted ;-).

Hmmm,

that means we can run micropython on the upcoming new generation of e-ink devices which will base on the i.MX7.
Wait until those units are cheap enough and we will have an display unit in form of an programmable e-ink display to show calendars, sensor data, weather or other IoT stuff.

My UART problems are solved.
It works fine, now.

I have one raspberry that would be the next target after i.MX6. If by then no one else has it already been ported.

Now I try to display the repl prompt over the HDMI or LVDS connector. And the support for a keyboard.
furthermore at this point the MicroPython-lib is not complete there also needs some more time.

Small update,

currently able to run:
* communication over UART (debug interface)
* Set Pin and toggle output state
* Display (only pictures no video content)
* Temperature monitor

Next,
* USB

Do you have some news about porting?
Are you planning publish code?

Hi Honza,

not found much time to work on.
Currently working on CDC (USB).

I would publish the code but I do not know if I could publish the code of NXP (Freescale) on Github? Because I use the driver package from NXP.

Hi,
the USB CDC support is done.
Next will be MSD.

I have found the the LICENSE of the NXP/Freescale SDK, which I use. Can anyone tell me if I can publish uPy port with the NXP/Freescale code? Only what I have to do is to check the disclaimer in each file, right?
