STM32F4 Discovery LIBMaple DFU issue..

Hi guys/galls..

I have read up on the forums and found this:

http://code.google.com/p/stm32f4discovery-libmaple/

Which has allowed me to get so far..

I seem to have managed to get the bootloader on to the discovery, changed the target path etc ('Need to update variable PATH to Sourcery_CodeBench_Lite_for_ARM_EABI\bin directory') and seemingly have succeeded to this point.

I have changed the driver with ZaDig util and placed jumper between BOOT0 and VDD pin to enter DFU.

I run '_build_.bat' and it pings 127.0.0.1 5 times.
It posts that there is 0% loss of packets.

Then it gets to the filter on vendor.

According to the ZaDig util my USB ID is VID 0483 PID 3748 which matches the hardware ID of the STM32 in the device manager.

After changing the driver my discovery appears in the Universal Serial Bus devices list as 'STM32 STLink'.

However, when the build gets to filter on vendor it seems to be looking for vendor = 0x0483 and product = 0xdf11 and claims there are no DFU capable USB devices found.
I have tried changing these details in the makefile, which makes no difference what so ever.

I also tried to go back to using the original driver which is now is also not recognizing. (No STLink detected).

I am not sure if there is supposed to be a change or not in the device manager when I activate the DFU? I am familiar with 8/16U2, which does change when you put it in to DFU mode, but my discovery does not.

I am now stuck in the situation that I can not continue on this route, or go back to the original setup which I am finding very frustrating.

Any help on this would be appreciated!

I may have found one issue..
When I run 'clean.bat' I get the error '/build-targets.mk:5 *** multiple target patterns. stop.'
Therefore can not change the ID to match the correct one..

Not sure how to fix this..

I would run this under linux, but last time I set up a dual boot and updated linux it knocked out 3 of my partitions locking me out of all my data!

Any clues?

I tried Wubi to install linux, which now has locked up on install.. So totally stuck for working in linux or windows with this..

Shame because I was hoping to get this up and running by now.

I'll keep an eye on this thread, if anyone has ideas as to how to go about fixing this I would be very grateful!

You are mixing up things here. The board has two USB connectors. The mini USB connector is connected to the on board STLink-V2, which can be used for debugging and also for flashing, the micro USB is connected to the F4.
There is absolutely no need to change any IDs, as the IDs are correct.
Besides that, the latest sources are at https://github.com/AeroQuad/AeroQuad/tree/development/Libmaple

Ah I see!

Thanks ala42.

So I need to connect through the the smaller port and run this? (Closest to the M4 not the other IC..)

I will try this and let you know how I get on..

One thing however, I now can not access my STM via the STLink as I would by default?

How do I get this to recognise as it didn't originally?

I seem to be stuck in some form of limbo that will not allow me to revert or recognise this and flash as before..

My bad..

I have got it back to the original set up now..

I know this is is probably a real pain, as I am kind of getting out of my depth here..

I seem to have the board linked up, although there were a few errors, but my STM is now blinking and as I had erased the IC previously I take this is correct?

Is there a listing of the new config for the IO or can this be deducted form the docs at ST?

I am guessing that I now compile the program in the Arduino/Maple IDE, find the .bin and then upload via the STLink?

If this is correct I will be a very happy bunny!

Hi
I have STM32F4 discovery board,I have also tried the modified libmaple but I couldn't compile the code from git repo, I'm using windows 7 and I followed the instruction from the wiki "Command-line compilation and manual uploading" ,I'm getting the following error " C:/MinGW/msys/1.0/home/ang/AeroQuad32/MapleCompatibility/stm32.h:215:2: error: #
error "No MCU type specified. Add something like -DMCU_STM32F103RB " "to your co
mpiler arguments (probably in a Makefile)." and if I try the build bat file well it show much more errors
I did modified the Makefile and replaced aeroquad32 to discovery_f4 as Ala42 pointed in another post
Can you help me please , I'm not familiar with make files ans command line and I searched a solution for a days with no success
Thanks in advance

To build libmaple, you just have to start build.bat in the Libmaple\libmaple directory.
To build the aeroquad firmware, edit Aeroquad\Userconfiguration.h. Comment out line 43 and remove the mommend from line 50, so you get
//#define AeroQuadMega_v21 // Arduino Mega with AeroQuad Shield v2.1
#define AeroQuadSTM32 // Baloo board
Then build the binary by starting Build.bat in the BuildAq32 directory. You better first edit Build.bat to use make -j1 instead of make -j4, as compiling in four parallel threads messes up the screen output.

Thanks Ala42 for your quick replay
I found the problem was coming from Sourcery Code bunch, I was using a new version, now I have updated my path to use the one shipped with Maple IDE and I can compile some code from the example folder Which version are you using please ?

PS I couldn't sign into this bb so I opened another account I was getting an error message the page your looking for is unavailable for 2 past days

I use gcc version 4.5.2 (Sourcery G++ Lite 2011.03-42) for quite a while and now also the gcc 4.7.3 from the launchpad site, which produces the better and faster code.

Hi Ala42
I have installed the same version as yours now (Sourcery G++ Lite 2011.03-42)
I'm trying to compile a project which run fine in Arduino and Maple Ide and I'd like to use the STM32F4 but unfortunately I'm getting this error
./support/ld\libcs4_stm32_high_density.a(start_c.o): In function `__cs3_start_c':
start_c.c:(.text+0xd4): undefined reference to `main'
collect2: ld returned 1 exit status
make: *** [build/aeroquad32.elf] Error 1

searched Google but I cannot find anything
Any help please
Thanks

As the error message says, the main function is missing in your project.
The main function is were you put our application code.

There is an example of a main.cpp file containing a main funtion
in the main.cpp.example file that you can find in the top directory
of libmaple distribution. You can also look at the files in the example directory.

Regards
Magnus

Hi mlundinse, of course I have changed the project name to Main.cpp before compiling !
Under Arduino it was splited into Tabs so I've make small change to Arduino preference so that it will give me the .cpp file (added the build path )
Maybe this what cause the error !

There must by a function named main in the Main.cpp project.
Its not the name of the project, but a specific function in
the project.

When you do Arduino or Maple-IDE sketches the main function is hidden away
in the main.cxx file that gets added to your sketch by the Arduino
IDE tool.

Thanks mlundinse ;I've added that magic part and it does compile after that I uploaded the discovery_f4.bin with ST-link
Actually the Serial over usb doesn't work as there's no new COM port showing in the Device manager ,I'll take look into Aeroquad code to see what I need to modify in my sketch
