Eslipse and DFU

Hello, I’m playing with SMT32 + SPL and Eclipse over two years… Now I can using DFU for upload firmware. I try upload to chip Arduino-SMT32 bootloader and test simple blink LED example in Arduino IDE. It is working without any problem. Bud I can using this bootloader (DFU and VCP) in Eclipse (using SPL, no Arduino library). What I must change for example in LD script or somewhere else for successful uploading? Chip is STM32F103C8T6 (64 KB FLASH, 20 KB SRAM).

Thanks, MG

Too many forum references for Eclipse… but the site is fully indexed.

Click for Google search The first results looks promising.

OK, forgot to Eclipse (I’m using Eclipse only as IDE with external makefile)…

I want to use makefile + SPL, *.LD, *.S. Nothing else and of course dfu-util.exe.

For example: I have main.c for simple LED blink and makefile (plus SPL, LD and S). No Arduino library or source, no Arduino IDE. Command “make” generate hex file. This file I uploading with st-link to MCU and LED blinking. What I must make when I can upload this hex file with DFU util. Burn Arduino-stm32 bootloader and? Edit LD script (set right start address – skip bootloader)? Anything else?

Thanks

Add a custom post build step in the property dialog:

I think this is not too simple only edit post step (do you mean dfu-util.exe). I think it is necessarily edit LD script too (currently I’m not using arduino bootloader).

Yes make the last step an upload step using dfu

Or you could just configure an external tool menu item (Run menu)

http://help.eclipse.org/kepler/index.js … unning.htm

Or you could create a custom makefile for your project instead of using the one eclipse auto-generates.

Maybe we do not understand… This is not as easy as I found.

LD script is must be modified – ROM (rx) : ORIGIN = 0x08002000…
After make hex respectively binary (-Obinary) it is necessarily make MCU reset (reset.py – through VCP).
Then I can upload binary to MCU (dfu-util -a 2 -d 1eaf:0003 -D xxx.bin).
It is working.

Bud there is a small problem. The part of the main program must have VCP init because after upload binary to MCU, MCU (USB) stay in Maple DFU mode and I can’t make software restart when I can upload another firmware…

Yes, bud from Aurduino IDE/Arduino sources. As I said I can using DFU and VCP outside Arduino environment, only with SPL (no Arduino IDE, no Arduino sources etc.)…

Sorry for bringing up an old thread.

But, im strugging to get this working.

Trouble is I dont know the arguments to pass to the dfu util… in mac.

Ive got eclipse mostly working now but I cant upload using the normal arduino serial method and I cant time the manual reset correctly. As manually resetting turns off the board and hides the serial port.

So , what arguments do i put in?

dfu-util is a open-source package that is available on Mac, Linux and Windows.
Here is the manual page for it:
http://dfu-util.sourceforge.net/dfu-util.1.html

I assume that you are using it with the maple bootloader (https://github.com/rogerclarkmelbourne/ … bootloader)
Then you need to
1. pass VID:PID of the USB device using “-d” option
2. pass alternate settings using “-a”. There are three alternate settings available in the bootloader which points to three different locations.
0: RAM
1: Flash 0x8005000
2: Flash 0x8002000
The choice of these depends on where your user application is compiled at.
3. pass the user application binary file you want to download using “-D”

Then you need to manual reset it as I believe the bootloader goes into dfuMANIFEST-WAIT-RESET state (I might be wrong here).

Thanks, sadly i have a new problem…

I discovered that for some reason it was trying to trigger the WIN version of the dfu… And i couldnt find an option that forced it to use macosx, so i basically copied the MAC files into the win dir…

Kinda worked, managed to get it to upload. But I have a new problem… I think its either corrupting the upload or the builder in eclipse is compiling a damaged file. As once its uploaded. The board doesnt run the program or is crashed. And i even have trouble with getting serial to see it after this.

Reuploading using DFU from the arduino IDE fixes this. I assume corrects the bootloader or programme.

Is eclipse system getting flagged as windows and performing bad builds or something?

I really want to get this to work…

Well really interestingly… If i upload the same sketch from the arduino ide it uploads and runs fine.

if i upload from eclipse(sloeber) i get it to upload, but doesnt seem to run. And the serial port disappears as if its crashed or something…

So i assumed that eclipse is building a bad binary… However. i uploaded blink through Eclipse and it ran fine.

Really confusing.

i only have a few libraries included.
#include <Adafruit_NeoPixel.h>
#include <ThreadController.h>

Maybe eclipse is reading from a different library or something. its rather confusing me.
