Yes, take a look at arch/arm/include/stm32f0l0g0
But keep in mind that STM32F071 has only 16KB/20KB RAM, it could be a
limiting issue if you want to use USB and Ethernet (ok they don't have
peripheral to it, but you could want to use ENC28Jxx for example), so
feel without of memory very soon.
For realtime control and maybe simple Modbus applications it could be an option.
As a side note: some years ago I helped a company using NuttX on
SAMD21, it has 32KB RAM, but they needed to use Modbus, GPRS (2G
Modem), ABNT-CODI, Analog Input, Digital I/O, external RTC, Battery
Manager and Low Power Support, HTTP Client (with DNS support), etc.
Eventually we got everything working, but it was really challenging,
the configuration was very well tuned to support it, as well their
application.
So, as Mr. Bill Nelson said few days ago: "You can only get so many
pounds of potatoes out of a five-pound sack". If you want to go big,
use a MCU with enough resource to avoid future issues.
BR,
Alan

One question, nuttx runs on STM32L071 ?

Hi Nathan,
Yes, I already suggested it, but he didn't submit a proposal to the
N.O.W. event yet, he was waiting to get more features supported.
His post is gaining a low of visibility, let see if someone from
Microsoft will see it! ;-)

This project is really nice.
Isn't it good enough for a presentation at the workshop?
Best regards,

Hi Nathan,
Yes, I already suggested it, but he didn't submit a proposal to the
N.O.W. event yet, he was waiting to get more features supported.
His post is gaining a low of visibility, let see if someone from
Microsoft will see it! ;-)

Thanks for sharing.
Maybe extend an invitation to them to post about it here or speak
about it at a NuttX event?
Cheers,
