SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

LoRa - REGION_AU915

Posted by jsayed1 on 2017-12-19 20:23

Hi all,
First my apology, if this is not the appropriate forum for my question, if not please guide me to the correct one.

I have two ST Micro LoRa Development systems (B-L072Z-LRWAN1, discovery cards). - http://www.st.com/en/evaluation-tools/b-l072z-lrwan1.html.Question

I have installed the AC6, OpenSTM32 tool bench for STM32 on window 10.
http://www.openstm32.org/HomePageQuestion

I downloaded the ST Lora Stack – I-CUBE-LRWAN
http://www.st.com/en/embedded-software/i-cube-lrwan.htmlQuestion

I am working on the sub-project in it called AT Slave.

I have two questions:
a. Is this the correct LoRa stack I should use on MuRata module?
b. As default AT_Slave application is set for REGION_EU868. I like to
set it to REGION_AU915, I don’t know how to?

Thanks

One of the first lines in main.c is defined( USE_BAND_915 ) so just put the setting in the preprocessor defined settings in the properties of the project.

Hi Mark,
Thank you for our email. I have already tried this procedure several time but it does not work, couple of points.

a. There are 4 projects (sample code) in this package Only one project (PingPong) uses the USE_BAND flag.
The other 3 projects use REGION_XXXX such as REGION_EU868 switch. Its described in region.h file.

b. I changed the pre-processor flag as follows:
project> Properties > C/C++ Build > Setting > Preprocessor
it had following setting:
STM32L072xx
USE_B_L072Z_LRWAN1
REGION_EU868

I changed REGION_EU868 > REGION_US915  but it does not change the frequency sounds like it hardwired to the EU868 switch, I tried finding the define statement in the code but was unenable to do so.

will appreciate any help,, Thx
