FMC with NAND Flash 8 times slower than expected
I am evaluating NAND Flash as a means of storage for a product. I am using the Toshiba TC58NVG1S3HTA00 and using it with the FMC on the NUCLEO-U575ZI-Q board. While I have established comms and have been able to read, write and erase the flash chip s...
Resolved! STM32L431: Enable EXTI on a Pin Number Used as UART RX on a Different Port
Hello,I would like to configure PA11 as an EXTI pin. I know that there exists the hardware limitation that there cannot exist two pins with the same pin number in different ports configured as an EXTI pin (I.E., I could not configure both PB11 and PA...
STM32G0B0RET6 failure rate
We are on the second generation of prototype here. On the first generation I had an MCU fail for reasons I couldn't trace. This was from a set of six. I have now powered seven of the second generation two have had MCU failures. The second failure w...
Resolved! How to disable XSPI SCK Clock preamble?
Good day Folks,I am hoping you are able to shed some light on this odd XSPI clock behaviour. I have connected XSPI2 to a W25Q64 Flash in QSPI mode.There are 'preamble' clocks present prior to the NCS being asserted. I've noticed that the number of p...

STM32H745 Bootloader and RAM on STM32H745XI-DISCO
I want to create and application on a STM32H745XI-DISCO. I am not using M7 core only M4.Reference manual says that upto 864kB of SRAM and 2MB of flash are available.I will receive the application sw via Can. My bootloader will save it RAM and after ...
ADC Multichannel - DMA on STM32U545
Good afternoon, I have some questions for reading multiple channels of the ADC in continuous mode and map the results in the DMA. I have been able to monitor the voltage coming from a potentiometer and map it into the DMA and i can see the values in...
ADC - DMA - TIM
Hello everyone New STM32 user here, more specifically STM32 U545 RE-Q. I am kind of new and i would like to start acquiring some data with the STM32 ADC, triggered by a timer, and send the data to the DMA so that i can use the CPU for other stuff. D...
Resolved! I2C Slave device implementation ACK/NACK problem
As mentioned in the topic subject, I would like to implement I2C Slave device which will simulate the BQ769x2 device. For development I'm using STM32F4 Discovery board, but the final product will be deployed on STM32L0.Master device is first trying t...
