Hello, I found this handy site with example code on getting free space on a USB connected to my STM32F7. The example code says "assuming 512 bytes/sector"... but I can't get the math to work out. How do I tell how many bytes per sector is on my USB d...
This is the second time I’ve asked for help about coding a USB MSD bootloader for the STM32L4 using the STM32L4R9I-EVAL board. I gave up for a while but would really like to figure this out so I can move forward and be able to use the STM32L4. I used...
Hi team,I am new to CubeIDE, just wondering how can I monitor the stack userage of a FreeRTOS task? Is there a built in feature that I can use, or do I need to fill the stack with some known data the monitor it manually?If using the second method, ho...
