Why can't my STM32F469 hardware enumerate correctly USB sticks?

Hi all.I have a hardware with STM32F469, running FreeRTOS and USB stack as configured from CubeMX.I have the following problem. I have a preproduction stock of this hardware and 2 USB sticks.Let's consider only 2 of the above boards (let them be A an...

Dividing hardware timer in software

I have a hardware timer using its updateEvent interrupt to increment a ms_passed variable every 1 ms. I have a freeRTOS task reading ms_passed ( via TaskNotification ) in a while(1) loop to toggle a pin at a given time interval/tempo based on a vari...

Why is the bootloader of STM32F072RB moving PB12 Pin? it's not mendioned in AN2606.

I'm working on a custom board with an STM32F072RB as microcontroller. I'm testing the firmware update via USB and I found that as soon as I jump to the internal bootloader (address 0x1FFFC800) the CPU goes down. Looking at the enables I found that t...
