Update STM32L47 Firmware from SPI memory

This is for firmware Over the Air(FOTA) updates. This is an mbed-os based device.My device will be told there is a new FW image and subsequently load it down to an on board SPI memory. I then need to load that image into Flash and make it active. Thi...

Nucleo-f746zg input_capture not working

I'm trying to get the basic input_capture example to work. I've created a project for the nucleo-f746zg board using cubemx and I've followed the cubeF7 example for input capture to be able to capture the ON time of the blue push button on my board. H...

WWDG Reset on Low Battery

Hello,I am using a windowed watchdog and resetting (petting) the timer in the EWI interrupt. I also kick/pet it in my main loop at 1000Hz. Time is kept via a systick handled flag. Systick, to my knowledge, is attached to the system core clock (same a...

STM32L4S5ZIT: USART1,2,3 BRR(Baud Rate) configuration is not changing dynamically

STM32L4S5ZIT: My code is dynamically changing the AHB prescaler 1 or 2. I am using HSE external 6 MHZ crystal oscillator. So my program dynamically 6 to 3 & 3 to 6 MHZ will be changed through AHB prescaler(I am not using more than 2 prescaler). I a...

Illogical Prescaler Behavior

I wanted to see what would happen when I set the prescaler for an interrupt lower and lower.My expectation was that the main loop would lose out on it's share of processing time, but I was surprised when the results of my test were mixed.Essentially,...
