STM32L1xxx µC displaying memory contents

first of all would like to greet everyone from my side. I am working as an intern and working with STM32L152 EVAL board. I am supposed to take the digital values from the ADC converter from an analog input and save them for the first run. In the second run I have to save the second values and compare

Yagarto: Cortex-m3 linked ok, Cortex-m0 not

I have a lot of projects with stm32f1xx CPUs (cortex-m3), all is good with them. Now I decided to make project with stm32f051 (cortex-mo), and linker works with errors. I have several cpp files (task is to light-up LED), they are

done. I use Yagarto with GCC v.4.7.2. Here is output: arm-none-eabi-g++ -T"D:\Nute\_tmp_\f0test\STM32F051R8.ld" -Xlinker --gc-sections -Wl,-Map,f0test.map -mcpu=cortex-m0 -mthumb -o "f0test.elf" ./src/main.o ./lib/src/stm32f0xx_rcc.o ./lib/startup_stm32f0xx.o ./lib/system_stm32f0xx.o ./kl_lib/

STM32 GCC problem writing to flash bank 2

STM32 and Programming via Boundary Scan

Hello, im currently writing on my B.thesis about boundary scan and its implementation. I`ve found enough informations about the principle of boundary scan and how to test with BS. However, i didnt find a lot informations about using BS to program a µC. Can anyone provide my informations about programming with BS? How efficient is it? Another question that has to be answer is if BS is useful for our products. We have quite a lot analogue devices such as analogue control stages or other complex analogue components. In some cases, we only have 1-2 digital devices (µC,..) on the PCB. Is it useful

Advantages of Hard/Soft FPU Compiler Settings

about the "overhead", maybe somebody else can. As far as I can see (I just made a few tests with STM32F4 Cortex M4 and GNU tools) the main advantage of the soft-abi is the possiblity to "mix" libraries which are only available as object code (archives/"a-files").
