Rak811 Tracker Board

Checkout this,

Maybe they moved something around or is using a different version , _estack should be defined here,
src/boards/rak811breakboard/cmsis/arm-gcc/stm32l151xb_flash.ld
but maybe you are using linux?
src/boards/RAK811BreakBoard/cmsis/arm-gcc/STM32L151XBA_FLASH.ld

Maybe the guys at RAK used a filesystem that is not case sensitive and yours is.
Can you paste the full link command?

You can change classA.coproj from,
LocateLinkFile path="…/…/src/boards/rak811breakboard/cmsis/arm-gcc/stm32l151xb_flash.ld" type=“0”/
To
LocateLinkFile path="…/…/src/boards/RAK811BreakBoard/cmsis/arm-gcc/STM32L151XB_FLASH.ld" type=“0”/

I also started experimenting with a rak811.json board file to be put in,
~/.platformio/platforms/ststm32/boards
Should be possible, then you can have board = rak811 and framework=cmsis

Compiling with platform io,
I have put the complete platformio RAK811 code here,

The blink program is working but timing is way to low and there is no debug output

julian-1 · February 10, 2018, 11:07am

I use Segger RTT in other projects (but not the rak811 yet) and the devices definitely run without the debug probe connected. not sure why that would make your project not run on normal processor reset?

OlofAst · February 10, 2018, 11:16am

The code runs without being connected to the debugger and I can see packets with size 21 on my gateway.
I changed OVER_THE_AIR_ACTIVATION to 0 in Commissiong.h
I will commit a request for a new board RAK811 to platformio.

will have a go later, where do the board json files live?

BoRRoZ · February 10, 2018, 12:36pm

I just sit back and see your guys working really hard to crack this board … great work !

frml55 · February 10, 2018, 1:05pm

@julian-1: Thank you. I will check the differences this afternoon. It‘s really hard work in comparison to Arduino-workd

OlofAst · February 10, 2018, 1:45pm

On linux they are stored here,
.platformio/platforms/ststm32/boards/

Should be something similar on wondows.

I managed to get packet through to my app on the things networks so it seems to be working.

Verkehrsrot · February 10, 2018, 5:24pm

May RAK811 arrived. What’s the easiest way to get in online on ttnmapper.org?

jezd · February 10, 2018, 11:09pm

Huge thanks to @OlofAst on this, all working on Windows 10, Visual Source Code, Platformio addon, used your github code (see post above) as it is for testing.

Dropped in the new RAK board json file
Created new RAK811 board project
Copied Lib, Src and platformio.ini files across to the new project
Changed Commissioning.h device settings
Compiled, few warnings but did ok, BIN file created
Burn device with STM flash loader demo gui, had to use (STM32L1_Cat2-128K) to get it to work?
Work well with OTA, sending movement, battery and temp data via Cayenne (pre coded for this)
Interesting that it joins on SF7 here and then falls back to SF12, will see how ADR behaves re this

Thanks, I would never have got this far on my own!!

Lots to do now in terms of testing, lowpower, changing etc - not got GPS on my board (ordered two tracker boards from RAK).

anyone seeing ADR working on this board?

OlofAst · February 11, 2018, 8:48pm

Hello frml55
For some reason the wrong link script is used,
“-LC:/Eigene Dateien/0_Familienmitglieder/Maze/IOT Allgemein/RAK811 Tracker/coIDE/classA” “-Wl,-TC:/Eigene Dateien/0_Familienmitglieder/Maze/IOT Allgemein/RAK811 Tracker/coIDE/classA/link.ld”

Should have been this,
-TC:/dev/TRA/LoRaWAN/RAK811/FW/src/boards/rak811breakboard/cmsis/arm-gcc/stm32l151xb_flash.ld

Double check the LocateLinkFile path in the ClassA.coproj file

frml55 · February 11, 2018, 9:02pm

@OlofAst: Thanks.
I had no idea, but searched for *.ld files and found these:

Then I renamed “STM32L151XBA”_FLASH.ld to “link.ld” and copied it to the directory of link.ld

Full sucess.

Then I found in CoIDE configuration “Scatter file” and placed the right Linker file there:

And it worked again

Now last question: Is “STM32L151XBA_FLASH” or “STM32L151XB_FLASH” the right one?

frml55 · February 11, 2018, 9:58pm

Both link files are working.

Now I have my “RAK811Breakboard_classA.elf” and “RAK811Breakboard_classA.bin”

But what to do next to connect the board to TTN and Cayenne?

OlofAst · February 11, 2018, 11:24pm

To connect to the network you should edit the file Commisioning.h

Is “STM32L151XBA_FLASH” or “STM32L151XB_FLASH” the right one?
One is for the 16KB verssion of the board, If both works you probably have a 32KB version and should use XBA version of the ld file as it should allow you to use more RAM.

OlofAst · February 12, 2018, 1:31am

Hello again,I also got printf to work.
I moved the printf.c source file from lib/Retarget_printf/src/ to src
Also added -fno-builtin flag to compilation flags but not sure if that was important.

I got Move detected INT1 whenever i move the board.
Move Detected INT1 src:0x60
Move Detected INT1 src:0x60

I dont have a gps on my board.
