When I refactor a global variable or function from its definition in a source file, all instances are replaced except the declarations in the header files.Attempting to refactor from the header file achieves nothing. The new name is immediately repla...

I am attempting to configure the quad spi peripheral on an stm32f469 microcontroller.The address space for the QSPI starts at 0xa0001000.However, the address space from 0xa0001000 to 0xbfffffff is inaccessible. Attempting to read or write to these r...

I am developing a serial comms protocol between two STM32F407s.I am using the hardware CRC module to generate checksums for some of the data.I am also writing a test script in python to aid development.All has gone well until now.Now I need my test s...

Target device STM32F407VGI am getting a hardfault that occurs only when not debugging.Using RTC_BKP registers I have tracked the problem down to a function call that passes a pointer to a struct.This struct contains a pointer to dynamically allocated...

Reboot fixed it.

FWI, I have this problem today. No reason, nothing has changed. Suddenly "Failed to enable SWV".This forum post is the only google hit I got.Will report back if I solve it.

Sources are in `/module_name/src/`, headers are in `/module_name/inc/`If I Ctrl-Click on a definition, it takes me to the corresponding declaration in the header file. Likewise, Ctrl-Tab will take me to the header file for that source file.Checking P...

Hi Clive, Thanks for your response.I've done a bit of investigation with the STM32F4xx StdPeriph driver examples.This has revealed... that the wrong chip was fitted to the board :grinning_face_with_sweat:.I was clued in by hardfaults occurring when ...

Thanks. Yes, I completely lost the plot and had two variables with the same name. :)Also, param x should be false to match STM32CRC.Corrected.Though now the code I use looks like this:from crccheck import crc def crc32stm(inbytes): inbytes ...

Refactor ignores header files. Why?

STM32F469 Quad SPI registers inaccessible.

STM32F4 CRC32 algorithm headache

Pointer value changes when not debugging, causing hardfault.
