I think I've set up everything sensibly via STM32CubeMX to get HAL control of the LSE, but the external oscillator appears to be not operable. In particular, there is essentially no voltage on the 32kHz crystal pins, so of course it will not oscillat...

Posted on September 03, 2014 at 17:26I've been trying to run the system bootloader from my application on an STM32F205.  I think that should b feasible, but at present the system firmware behaves badly.  Probably I'm doing something wrong, but I can...

Posted on July 25, 2014 at 10:33Hi, I'd like to program STM32F373s via their usart1 from an STM32F2, though the latter should be irrelevant, I think. The board has the STM32F2 controlling four STM32F373 processors as peripheral controllers and talks...

Posted on June 11, 2014 at 13:44I have a curious behaviour with USB that I can't presently understand. I have a dual CDC/VCP of an STM32F205 HS_FS USB port with the internal phy in FS mode. When connected to a Linux machine, the USB enumerates and r...

Posted on October 11, 2013 at 13:25Hi, If I had a suitable board, I'd just try the obvious, but I don't presently have one. I'm pretty darned sure this is a dumb question, but if I'm wondering, I guess others may do as well, so here goes. In AN2606,...
