Hi, I am running into an issue running developed firmware an STM32L452RE uC on a custom PCB. I am able to program the uC fine, and the debugger can open (I am running Keil). However, the firmware does not execute. It sits at a random memory position,...

I am currently using an STM32L452 MCU that operates using a custom bootloader and firmware package for operation. I have leveraged the bootloader on other projects before, so I knew (or at least thought i knew) it was solid. I'm learning that when i ...

Hi,I am currently trying to switch my code base from the RB version of the L010 family to the K4 version. I am doing this because the dev board I prototyped on was for the RB variant. I am building with arm (Keil).I am running into some issues in thi...

I currently am working with a stm32L010K4 mcu, but i have a startup script for stm32l010xB (startup_stm32l010xb.s). Where can I find a startup script for the stm32L010K4 mcu -- I'm guessing the name is startup_stm32l010x4.s ?

Hi--I/m pretty stumped. I am trying to implement a odd parity configuration for USART1 in an stm32L452RE micro. I've confirmed without parity the usart behaves as expected at the needed baud. When i introduce parity into the code and sniff the data o...

Interesting, ok. So by that logic it makes sense that VTOR isnt being set since SystemInit isnt being executed. Yes, I removed run to main in the compiler settings. It just floats around the 0x1FFxxxxx hex range, no written code which is readable is...

Hi, I have the code instrumented for hard fault handling, and the handler itself is never hit. I dont think the vector table is getting programmed properly, but i dont understand how that can be. My reasoning for that thought is VTOR is 0x00000000 wh...

Yeah, so i figured out my issue -- i was inspecting memory/registers as i completed my erase prior to write, and noticed that my memory erased was a few pages off.Digging into this more, i learned this offset was due to my utilization of the uint32_t...

Issue executing programed firmware on STM32 uCs onboard custom PCBs

Issue using the HAL internal flash memory interface when leveraging a bootloader and firmware memory structure.

Switching a code base from stm32l010RB to stm32L010K4

Where can i find a repository of startup scripts for the st micros?
