STM32 boards

[LisaM]

Solved the mystery, it was a single line of code! Changing this in the hal.py file from:

Code: Select all

#core._nic.active(1)

to

Code: Select all

core._nic.active(1)

Solved the problem. In hindsight it makes sense, the nic was there, even with an ip-address, but not active so it couldn't receive data...

Fantastic! Good spot!!

Difficult to see in this forum topic which board specs will and won’t work. Ie. memory required for code, etc.

Will this board work?

STM32 ARM Mini System - 72Mhz
https://www.robotics.org.za/6970622930693

And the pycom lopy?

I totally forgot the Lopy was ESP32. Since I have a couple of those, I will have to plug one in and see if it works.....

I gave the LoPy a try, the 2048 version loads and runs. I need to play with it more, but it appears to have issue keeping the AP information but that could be me not doing something correctly.. There were some other errors, something about MAC address not set, but that could be the LoPy comm module. Hard to say.

I was able to access several of the menus as well..

Thank you drum, I will wait until someone get there t working.

And the other STM32 I showed? Does it have enough memory?

No Idea. I only have 1 and I have not been able to get it to work yet. It may work in mine, I just have not spent a lot of time on it.

You have to remember uPyEasy is still in beta and is not perfect on anything yet. Los of potential but it's not there yet.

Thank you!

The mini doesn work, you'll need at least 1MB of flash memory! Also at least 196K of ram.

The pycom is using an ESP32 and hsould work, although untested since i don't have it.

Can you post the errors? i'm interested in the error.
I'm going to order the pycom GPy since it supports nb-iot.

I (2715) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE
I (2725) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE

This is all I get consistently today.

Is this an ESP32 or a STM32F4?
It looks like this is a brown-out, meaning your power supply isn't strong enough.
Can i have the entire log?

[Drum]

Well it is a ESP32 based LoPy. Power is coming from the computer, but that could be part of the problem. I will see if I can figure out how fix that and get a copy of the log file.

I just got a couple of ESP32 Nano boards I will try it on too..

Here is the log after updating to the latest version
The LoPy works much better with an antenna attached

I am still getting
I (3063) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE
I (3073) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUS

How can I get the log without being connected to the computer?

Thanks

But, you do get an ip-address:

I (5063) event: sta ip: 192.168.1.114, mask: 255.255.255.0, gw: 192.168.1.1
I

You should be able to connect to it...

[Drum]

Yes, and I have it running with syslog set to debug, but it is not what I see on "Screen".
Is it possible the
I (3063) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE
I (3073) system_api: Base MAC address is not set, read default base MAC address from BLK0 of EFUSE
is related to the LoRa radio and not the esp32? Or perhaps LoRa and Bluetooth?

New version is much faster on this.
