Problems with Code sourcery G++ , audio playback file

Dear All, Greetings !!! I am trying to build a code example given with the STM32F4 discovery board and am getting the following problems in the console/ after build "D:/eclipse_indigo/stm32f4discovery_fw/STM32F4-Discovery_FW_V1.1.0/Project/Audio_playback_and_record/inc/usb_conf.h

of the macros in a header-file which is included by all USB-codes. IRC there is such a file in the STM library, somthing like usbconf.h. Further information should be available in the manual of the STM32F-USB-Library. The STM32-forum at st.com might be a better place to ask such target-specific questions

Helios GDB hardware debugging & JLink

7.0.0.201109151620 I try it with Segger J-Link, with gdb command arm-none-eabi-gdb from eclipse. I am building STM32Test from yagarto. I pasted scripts stm32_ram_jlink_[12].gdb into startup tab of Debug Configurations, but... When I start debugging, I get error dialog "Error in final launch sequence" with

0xFFFFFFF8 (Data = 0xBF00E7FE) So gdb and segger jlink appears to work correctly. (the yagarto STM32Test.zip may not be perfect for my STM32F103RBT6) I think my problem is with helios to gdb interface.

GDB issue (cortex-M3)

help: http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/arm_memcards/index.html#chanfat_stm32 During development I have used Eclipse Ganymede, CDT, CDT hardware-debugging-plugin, Codesourcery G++ lite for ARM-eabi 2009Q1, OpenOCD (different but rather up-to-date versions), Amontec JTAGkey, FTDI-drivers and STM32F103CB for the tests. Debugging from Eclipse works as expected (well, at least what I expected/needed). A little bit of additional information can be found in the readme.txt.

hardfault when using snprintf

snprintf(buffer, sizeof(buffer), "%i", n); and it doesnt work. I end up with hardfault on the stm32 that im using. If i use the below statement it works fine snprintf(buf, sizeof(buf), "hello %s", wld); Im quite new to programing so what could i have missed /Dennis

Choosing the Right Microcontroller for Low-Power IoT Applications

For STM32 low power, better look at STM32U0 for lowest price, STM32U3 for lowest power and STM32U5 for low power and highest functionality.

Best overall balance: STM32L0, SAM L21 Best if wireless is needed: Nordic nRF52 Best purely for ultra-low-power sensing: MSP430 or Silicon Labs EFM32

New Luminary Stellaris microcontrollers (ARM Cortex-M3)

Well, there is a solution for the MP3 approach. The STM32 Primer2 comes with an MP3 player implemented, this time however tied to the Raisonance tools, which are great for the STM32 but not available (yet?) for Luminary. btw. I would agree that the old

am getting at. The new Stellaris joins the NXP1700 in the 100 MHz Cortex-M3 performance level, the STM32 is sort of close but right now not there. On the other hand, the STM32 is real, can be purchased through distribution, the Stellaris and the LPC1700 are real in the lab of Luminary and NXP but can

Newbie Qs about ARM Types and Lookup Tables in C

really like the MKxxxx (Kinetis) from former Freescale. But they are usually cheaper. I also like the STM32Fxxx from ST. On both brands (LPC and STM) you will find a nonvolatile bootloader on the chip, what is very convenient, because the programming does usually need nothing more than a serial line or

Thank you for your replies. I just got two STM32F4 Board from a friend. I guess i'll start with ST :) and go from there.

Linking order and startup files

linker script that works fine now, but I needed a little tweak: The startup code I use is startup_stm32f10x_md.s, taken 100% from the STM Standard Peripherial Lib. As I said, it works fine, but I had to edit the isr_vector section: [code] .section .isr_vector,"a",%progbits .type g_pfnVectors,

OpenOCD load and debug fails sometimes

show openocd.cfg. You may also just try: [code] openocd -f interface/<yourinterface> -f target/stm32 init [/code] which will use files from the "target library". I have used them in my STM32 projects with success.

how can i debug code in ram ?

I did test with STM32F103C8T6 ($3 chinese board, known as blue pill). The only thing I had to do is to write my linker script to put everything in RAM, then: 1. Put the jumpers at BOOT0 & BOOT1 pins to boot from RAM.

Possible wrong explanation on "STM Discovery as Black Magic Probe" page

Hi, There is a tutorial how to use the STM32 Discovery boards as Back Magic probes, and one section refers to why the DFU does not work on the STM32F429I board. http://embdev.net/articles/STM_Discovery_as_Black_Magic_Probe#F429Discovery_board_doesn.27t_enter_System_DFU_bootloader I believe the explanation is wrong, and the reason it does not work on the STM32F429I discovery board is that the USB OTG wired out is the USB OTG2 peripheral in FS mode. DFU supports the only the OTG1 peripheral, see STM32 AN2606, section 18.1.1, table 38. PA11, PA12 pins used

nsec-resolution time measurement with MSP430 or alternatives ?

While the STM32F334 has a timer with 217 ps resolution, it is a pity that this resolution is only for output, not for capture, as the poster asked. The Infineon Cortex Parts also have sub-nanosecond timers, but

capture. And datasheet download still requires a NDA! You can get about 5 ns resolution with the STM32F405 and bigger parts, running the timer at 168/180 MHz or LPC43xx at 204 MHz.

Interrupt handler in C++ File?!

You cannot do that as part of a class. I don't know the STM32, but my guess is that interrupt vectors are known by their global name, so they cannot be established using C++ name mangling. This also implies they cannot be hidden with in a class (class members

Suggestion on controller selection

external scanner or ohter input. Its just a thought and might be easier than a controller like e.g. the STM32F429 which has TFT driving, USB and e.g. SD Card ports. If you think about writing your own software from scratch, have a look at the Discovery Boards from STM, like the above mentioned F429 or the latest F7 series. http://www.st.com/en/evaluation-tools/stm32-mcu-discovery-kits.html?querycriteria=productId=LN1848

Cortex-M3 External SRAM and Flash Programming

general this may not be a good idea due to the speed of external memory access. For example, the STM32 external bus is only 16-bit and access time is significantly slower than for internal SRAM or Flash. Running code from external memory may be as much as 10 times slower. Jack Peacock
