Hi, I've got an application which is running on an STM32F746ZGT. During in the field firmware upgrades, it has to erase part of the device's internal flash memory and then write to the flash. The problem I'm trying to overcome is to enable the device...

Hi, I'm using the STM32L451VETx and I'm configuring the ADC to read from the internal temperature sensor however the readings are lower than expected. Typical readings at around 21 degrees Celsius are only 3 degrees Celsius. I can see some change in ...

I'm running this code in my application and it continuously reboots. I've since moved the writing of the option bytes to the programming stage to avoid it but want to understand what I'm doing wrong. FLASH_OBProgramInitTypeDef ob; ...

Hi, this seems like it should be a simple task but I have not yet found a way. I have a project that I created in STM32CubeIDE v1.3.1 and by default all peripherals I've enabled use the HAL drivers. I want to use the LL drivers however but there does...

Hi, I've got FreeRTOS and LwIP running on an STM32F746. The application has a TCP socket listening for incoming connections. Incoming connections are coming from multiple sources and unfortunately I'm seeing some of the connections get an ECONNRESET ...

Thanks for the suggestions. I've been stepping through the code, and I'm realizing that there's a huge chain of functions that also need to be moved to RAM in order for this to work as I want it to. That's where I'll focus now.

I've changed the .isr_vector section from ">FLASH" to ">RAM AT> FLASH" in the linker script and the code still works but hearing from @Pavel A. about the .rodata not getting copied into RAM by the startup code makes me question whether the vector tab...

Thanks for the tip, I can see in the startup code, only the .data section is copied to RAM, so will either have to move the .rodata section into .data or create another copy loop for .rodata.If I set up the MPU to protect against access to flash befo...

If I change the .rodata section from ">FLASH" to ">RAM AT> FLASH" my code does not run. What I'm doing seems pretty straight forward, not sure why it won't run? Any ideas?

That sounds like a pretty good explanation, I'll have to move more parts into RAM. Ideally I could move all code and constants into RAM, but my code is just a little larger than the available RAM.Would you recommend turning off instruction and data c...
