Why would code work when compiled with Atollic - but not with Code Sourcery ??

I successfully compiled the stm3240g Sample Project using Code Sourcery.

But, it does nothing on the Discovery Board.

But, this code is directly converted from as WORKING Code on the Discovery Board

- when compiled with Atollic Compiler.

-> Why should the Code not run successfully if it compiles by the Code Sourcery too ??

What could cause this problem - difference ? Would WinArm work any better ?

* Is there some Fuse Setting that I need to program into the Chip for the Clock ?

Hi,

Just a background fact.  I've been using CodeSourcery G++ with Eclipse for quite a some time and happy with it.  Before that I used KeilMDK and IAR, and the outstanding Eclipse IDE makes the coding lot more easier.  I'm using Eclipse CDT with Cross Compiler Support.  The CDT internal builder is used, as such the makefile is not needed.  Moreover, Atolics startup and linker descriptions can be used straight away, to start Hello World!  I even used Scons instead of make, and happy with it too.

Clive,

Any ideas from the code ?

Clive, Any ideas from the code ?

I seem to be missing a lot of the pieces (zipping up a complete buildable project might help, bit it is rather a mess), and you seem to have created rather a hybrid environment mixing the standard library code with a lot of other stuff which I don't have any visibility to. I'm not sure why that was necessary as the standard library is serviceable. I've been using GCC with pretty the stock library and example code and customize linker script based on the STM32F1 version I used, Lanchon's I think. And the Ride startup code. What USART are you outputting data too, and does the baud rate match expectations? If the data is garbled it's a pretty good indicator that the hardware and software have different ideas about what the clock rates/settings are.

I can only assume the problem is in the makefile or startup.S

Or low_level_init_0, low_level_init_1 or SystemInit Other functions work back the PLL settings, and HSE_VALUE. Another potential is that it's using HSI (16 MHz) vs HSE (8 MHz), you could direct the clocks out the MCO pins and measure it with a scope to confirm it's what you expect.

clive,

Sorry about looking messy. This is the result of dropping my working Port of stm3240g into a BlinkLed Project for Code Sourcery. I have not been able to get noticable executable code from Code Sourcery before this. The Usart is not enabled. The Startup is the Blink Led Startup - not from stm3240g, but it is calling the stm3240g clock startup. This is running on the Stm32f4Discovery Board. As I said for speed, the Heartbeat Led is twice as slow, the Beeps are lower in Pitch, and the usb is not working - so I think that is already clear as a problem. Let me try to put together a zip then. Try this zip:

You should be able to attach things here.

Missing fonts.h, pulled from another STM32 library Missing chip.h, fudged some code for STAT_P Builds with Yagarto GCC 4.6.2 Want to attach your out directory from Code Sourcery? Mine expired, not hot to do a reinstall or buy a license.

[jlchoobs]

Posted on June 13, 2012 at 04:29 Yagarto GCC should be fine. I have Code Sourcery Lite, but My current Toolchain is Linux GCC. Chip.his listed below. Fonts.his not needed. - Fonts are only needed with LCD which is not enabled. Should be able to compile with your Winarm. This compiles down to 16K bin in Atollic. But, compiles into 144K Bin in Code Sourcery or Linux GCC. - Remove Unused code seems to have no effect. - Withthe Zipthat Isent you, and connecting a SDCard to Stm32F4Discovery Board, will give you Usb FlashDisk when connecting second Usb cable back to PC running Windows. Just compile with WinArm or Yagarto, etc. This is a TestedWorking port of Stm3240g Firmware running on Stm32f4Discovery Board. I sent working Code - just needs configuration tweaks for Code Sourcery or Winarm. - Maybe Startup file issue ? - try using the other Startup_stmstm3240 as Startup.S - Here I attached the OUT dir - I had avoided this because it is 16MB. But, I would suggest just compiling this yourself - you stated that you wanted to try the Usb on your stm32f4disc board -- here you got it ... I would like to post this as the Stm3240g Firmware port for Stm32F4Discovery Board. It is already complete and working under Atollic. But, I can not get it to compile and runwith Code Sourcery or Winarm correctly. Can you give it a shot? - it would be appreciated. - I think a lot of other developers are/would beinterested in this. I already see manyrelated questions on the forum about this topic, - like Sd Card on stm32f4disc. ---
