STM32C011. Cant run sysclk from LSI.
Im trying to run SYSCLK from LSI on a STM32C011. But it appears as if the MCU is not running. I cant see anything in the datasheet that says the clock cant be used and it can be routed fine in the clock configurator. Am I missing something in the dat...
Reproducible ECC error in TCM memory, following a certain access pattern with STM32N657I0
Hey all, I have been debugging a nasty issue that I have been having over the last couple of days. I am using the STM32n657I0 MCU. The issue that I observed were random crashes in my code. Luckily the problem was well reproducible. What I observed wa...

STM32H750 and USB3300-EZK has stopped working
I designed a board that uses a STM32H750 with a USB3300-EZK that has stopped communicating over USB. It's been having intermittent issues for the last day or so (sometimes I'd need to power cycle the board before it would show up, but then it would w...
STM32H7R7: How to setup XSPI for external nor flash AT25XE321D
Hi,The external nor flash AT25XE321D is 32Mbits, support quad IO/XIP spi operation, max. 133MHz Freq. Std. JEDEC/SFDP. It is connected to STM32H7R7Z8J6 with with XSPI1 port-1 interface.I am using MX v6.116.1 to setup project for my board. By IDE v2.0...
Troubleshooting IoT Device Power Management with ST Microcontrollers
I have been working on an IoT project using STMicroelectronics' STM32 microcontrollers, and I have encountered a unique challenge around power management. My system needs to run on minimal power to ensure long battery life in remote applications, but...
STM32 ADC VREFINT / TEMP reads maximal value 4095
Hi,I’m trying to read internal temperature sensor on ADC1, but the ADC result is always 4095.I use STM32L471, and I know that the problem is not HW related, when I run a different bin it reads the temp ok.Tried to read VREFINT, raw value is also 4095...
