Any one can help to find the ST micro MCU part no based on the SMD Chip marking code?

Resolved! MCU hung after staying idle for hours

In our system with SMT32G041F6P6 powered by a battery, device gets to hung state when kept idle for few hours or days (randomly). We have already implemented a window watchdog to detect any faults. Even with watchdog enabled, we are getting this han...

STM32H743VG QSPI in double flash mode for driving external DAC

I need to make 2 DAC channels 4bit each. I plan to use QSPI in double flash mode.Task is to play prerecorded samples from RAM cyclically. Samplerate is 45Msamples/secondI plan to use DMA in circular mode to send data from RAM to QSPIAre there limitat...

STM32WLE5JC FatFS cannot open, read file, cannot get number of free clusters

I have been trying to use the FatFS file system to create a new file on the SD card, or to read a simple txt file on the SD card. However, I seem to be running into issues after mounting the SD card. Initially, I ran code to:- mount sd card in main- ...

Zephyr B_U585I_IOT02A BLE examples timeout and crash

I'm trying to run a few of Zephyr's BLE examples on the B_U585I_IOT02A development board. I have tried the beacon, peripheral, and peripheral_csc examples. These BLE examples all work properly on a Nordic nRF52840 dev board.Zephyr's blinky exampl...

Resolved! Can I use the STM32F446RE (64 pin package) with memory mapped QSPI external flash?

HI,I am using a STM32F446RE which is the 64pin package.AN4760 states that "LQFP64 supports only Bank1 and Single-SPI/Dual-SPI only"Does this mean that I am unable to use the QSPI on this chip to be memory mapped?When configuring the chip in CubeMX, Q...

STM32F407VET6 DEMCR base address

Good morning,I'm trying to develop a simple Hello World printf example by writting "Hello World" into the port0 of ITM. There are several tutorials telling that 0xE000EDFCU is the base address to set the bit TRCENA to 1. However, when I try to debug ...

Resolved! hash registers not defined in stm32h723xx.h

I am trying to use the cryptographic hash processor on the STM32h723xx, however, I cannot find the registers like HASH_CR defined in the device header files.Can someone please advise If I should be using the register definition from another MCU devic...
