Hi, I tried out yagarto to generate code for a cortex-M3 (STM32). I got it working, but I was surprised a whole bunch of exception handling code ends up in my binary (the source code is pure C) This happens both with my (complex) program, and the STM3210ETest small example project (yagarto howto page, STM32), if I add this small function: [c] unsigned long long xyz(unsigned long a, unsigned long long b ) { return a/b; } [/c] If i check the library, there are some .ARM.extab/.ARM.exidx sections
HI All, I have recently installed WinARM 20080331 and created a test build for the STM32F103ZE target device. I am able to compile, link, and execute all 'C' code and some 'C++' code correctly. The problem appears when I attempt to use the C++ exception handling mechanism. I have

Hi, I try my first programming on an STM32 Discovery Board (STM32F303). I was using avrs before for years :-) First step should be to get the SPI to work. My IDE is Eclipse with gnu arm eclipse-plugin. All I want to see for now is the
STM32F130 contains two adwanced timers - 1 and 8. But Keil's STM32_Init.c and its Configuration Wizard knows Timer 1 only. After "manual" programming it works but I cannot find its interrupts. How can I
For what it's worth, I had the same issue the other day. I was working on an ARM project with the STM32 Cortex-M3 MCU. The quick fix I tried was to use gcc.exe instead of ld.exe for linking. It removed the problem with undefined references, but after debugging the project I discovered that the toolchain

Hey, I'm encountering a strange problem with the hardware SPI of the STM32F407 [2] (discovery board). I'm trying to communicate with an UM7 IMU [1] over its SPI interface. When I try to read its firmware revision, I receive ASCII 'T71E' instead of the expected 'U71D'.

Hi, I am trying to use yagarto (arm-elf-gcc 4.3.3) for STM32. Everything works ok if I don't use printf. But I need to use printf, so #included <stdio.h>. It produced error: [pre] In file included from main.c:31: C:\SCARM\GNUARM\arm-elf\include/stdio.h
without errors, but linker produced many errors of this type: [pre] ../arm-elf/bin/ld.exe: ERROR: stm32f10x_gpio.o uses FPA instructions, whereas Hello.elf does not [/pre] Does it mean that the newlib that came with yagarto is compiled using FPA? Does it mean it can not be used for Cortex-M3? Is

the flash as spi, not as quad spi. - The GD32F303 devices have some small differences wrt to the STM32, that mean you cannot just compile micropython for STM32F4 and hope it will work on GD32F303. Gigadevice provides CMSIS and HAL, but what is missing is software that is known to run on this processor
Dear Madams and Sirs, im trying to programming / and reading an 1Mbit EEprom with STM32F030x. There are some issues i am working on and make me some headache. Im using the STM32f0xx_i2c files for working and a Keil Compiler (V5.17). My first problem is: Im using one of our
target, the entry address (PC after reset) and the stackpointer are completely wrong. I am using a STM32F107VC (Cortex-M3). Here is the output of readelf: [code] $ arm-none-eabi-readelf.exe -S project.elf There are 18 section headers, starting at offset 0x3884c: Section Headers: [Nr] Name
Try do transfer the code with the STM32 bootloader, for example with the flash loader demonstrator available from st.com. If it works there is a problem with the programming-settings in the IDE (model, flash-programming-algorithm, memory-regions
Hi, I am trying to get strncpy working. At the moment I know that it has something to do with the newlib. I am using coocox with https://launchpad.net/gcc-arm-embedded/ How do I include the newlib into my toolchain? Or am I wrong with newlib an the problem lies somewhere else? I included the syscalls from the repository: "The component implement the minimal functionality required to allow libc to link." I also included libc in the "linked libraries section". But it seems as if behind strncpy is only a declaration: "char *_EXFUN(strncpy,(char *, const char *, size_t));" I do not have
hint: check if, during the link process, the correct libraries are used. For example: I use the STM32 which got a cortex-m3 core and accedentially linked the libs for a other arm core. resulting in perfekt working code, up to the point on which I tried to use floatingpoint. that is, because the STM32 got no fpu and than the wrong lib was linked and used unsupported commands to emulate the fpu. You should check the main.map file, it includes the linked libs. then check if they are supported/compiled
