launchpad gcc for ARM: Understanding linker scripts

Greetings to all, I want to run code from a ram-location on a STM32F407 (Cortex-M4) microcontroller, but before I can do this, I want to understand the linker-commands, and this seems to be a real challenge. At first, I want to find out where some code-fragments

work, I got "bootstart = 0x20000804" and "bootend = 0xaf00b580", superfluouses to mention, that the STM doesn't have so much memory. [code] SECTIONS { . = 0x08000000; bootstart = . ; .text : { ... ... [/code] It's amazing, that the code generated with these linker-scripts

STM32F303 Discovery: SPI basics

Yagarto and floating point

general 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/

Problem with reset vector (Yagarto + STM32F107)

to understand how to use the yagarto tools (yagarto + eclipse + openocd + TinyUSB) with a Olimex's STM32F107 board. So far, using Olimex and yagarto examples, I have been able to compile the code. But the reset vector doesn't point to the correct part of the code. I have defined the vectors :

Encoder Timer switches between 0 and highest value.

problem could be. You probably need more information, im happy to give them to you. I work with a STM32H745XIHx. Thank you

So you configured the STM Timer for Encoder-Mode, but only one channel is connected. Thats wrong. If you use only one channel eg. for speed measure you have to configure the Timer in capture mode.

I think a lot has todo with the way you are masking interrupts. With the stm cortex you can enable a global method (cortex_m3 maskisr on|off) or use the DBGMCU_CR register. You are using the gdb hooks and the maskisr cmd. The only issue i see is you seem to have a typo in

trouble with printf on Cortex-M3 (STM32)

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

Weact Blue Pill + GD32F303

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.
