STM32F427ZIT6 lead time and availability issues

I have a product line using an STM32F427ZIT6 MCU which has been in production for several years. Suddenly it seems to be unavailable. Both Mouser and Digikey have zero stock and cannot even quote a lead time. Our production will be halted very soon. ...

RNG clock error on NUCLEO-L4A6ZG

I am trying to use the RNG on the STM32L4A6ZG but every time I enable the RNG clock RNG_CR |= RNGEN the RNG_SR shows CEIS and CECS.The AHB bus is at 80MHz and RNG_CLK is at 48MHz. I've tested with configuring the RNG_CLK to come from either the HSI48...

Hi, I'm testing libopencm3 libraries on a stm32f103c8t6 board. I have an erro that seems the st-flash tool is not able to record in the SRAM when I use a vm Debian GNU/Linux 10 (buster) , but when I use a VM with arch Linux the process is succesfully.

Attached images of both systems and I really appreciate suggestions to understand and be able to solve the problem in debian.
