Hello,

I am trying to find out GPIO mapping on a board with an STM32F407 (which firmware function is related to which GPIO). I know I could do it using a LA, but pins are note very accesible.

I have no access to source code so... I only have a firmware…

Our team has developed a custom SoC with embedded flash blocks and a Cortex M0. Given that the code flash download routine will have to be customized, I am looking for some help and information on how to get started. The SoC as a 2 wire SWD interface…

I am developing simple applications for the STM32F303k8 Nucleo board. I have the same version of KEIL uvision and MDK-Lite (5.28.0.0) installed on both a personal computer and a networked computer at my institution. I have developed simple code to test…

Hello,

I am looking for some help with my Keil uVision 5.27.  I am able to run some example code for my chip that I downloaded from NXP.  I have 0 errors and 0 warnings.  I am able to go into the debug mode, but when I set a breakpoint in the main code,…

Hi. I have an INVPC exception that I am trying to debug on a Cortex M4 STM32. The stack contains the following values:

0x08003555 xPSR
0x08006824 PC

The PC and LR both point…

I've asked is same question in stack overflow, but didn't get the response. Here goes,

Why is Stack-pointer register not reading correct value from another register? When I move a value from register (r0) to stack pointer (r13), the SP reads…
