STM32L412: When I turn the reset (physical) switch, the µC jumps into the DFU bootloader, although it isn't supposed to

2020-10-15
Hi there!I have a weird problem, where I'm a bit lost, probably also due to my limited knowledge of assembly. So I am trying to write a function (which is called using a very secret pattern) which sets a magic number and soft resets the microcontroll...

Linker Time Optimization introduces glitch/noise into Timer DMA controlled PWM

2020-05-11
Hello,I have an application on an STM32F042 microcontroller, and it uses Timer 2 configured as PWM output and is transferred over DMA.To fit the whole code into the small 32 KB flash memory, I am forced to use -flto (Linker time optimization). Howeve...

What do you do to significantly reduce code size? STM32F0 with 32KB Flash Overflowed

2020-05-11
Hey there,I have an STM32F042K6 with 32 KB flash which works with a whole bunch of peripherals using STM32 HAL and a lot of code. Now that everything is configured, it is overflowed by nearly 1.5KB (region `FLASH' overflowed by 1464 bytes).What I'll ...

Using an STM32F042K6 USB CDC, is it possible to request more than 500 mA USB power?

2020-05-11
Hey there,I'm using USB CDC, configured as VCP with an STM32F042K6, bus powered device. Now it seems pretty easy to change the default 100 mA to 500 mA according to here:https://community.st.com/s/question/0D50X00009XkZ8wSAF/stm32-as-buspowered-usb-d...
