QSPI reads only 0x9999
I have a custom board with STM32H747IGT6 MCU, which communicates with a S25HL512TFAMHI010 flash memory chip over QSPI. I have made several iterations of this board, and the QSPI communication has always been fine.However, on the most recent iteration...
Resolved! QSPI RAM on OSPI Interface of H7A3 MCU issues
Hi Guys,I need some help / input:I am trying to get the communication running between my Nucleo H7A3 and a Shield with a ISSI QuadSPI RAM in a SOP-8 Package running.Scenario:I am debugging with my Scope, I have a digital Probe on all 6 lines (CSn, Cl...
Problem setting up UART on STM32F756VGH6
Hi,I am learning and exploring the STM32F756VGH6. My goal is to setup a simple UART and send some data to the PC using USB-UART serial converter and puTTy terminal on PC. I am using register based coding approach as it makes the code more efficient....
Pull-up and Pull-down resistors in STM32 microcontrollers
Hello everyone,I have carried out some experiments on five different STM32 microcontroller devices (STM32F103) measuring the values of the pull-up and pull-down resistances integrated in the GPIO. I have created a voltage divider between VDD and grou...
RTC resets or stalls even with backup battery
I have an application running on STM32G491 which uses the RTC. There is an external 32768Hz crystal and a backup coin cell battery (I have checked that it is not depleted: 3.12V). There are two issues:Scenario #1: I pull the main battery, wait a bit,...
Resolved! Trouble with ADC accuracy
I am using the ADC on a Nucleo-L412KB board. I am setting up the ADC for single conversion once per second. I am getting digital values which are off, as though the Vref is up around 3.4 V. I have an LM385 voltage reference as a source and have t...
SD Card mounting error- FR_DISK_ERR, disk error occurred
I am using STM32L562 microcontroller. I am unable to interface it with sdcard using sdmmc and fatfsmy sd cards are- 8gb (formatted in fat32)[old], 32gb(unused)[new]. In both sd cards I am getting the same problem- disk error occurred (FR_DISK_ERR) it...
Resolved! Issue with Blank Screen in TouchGfx when updating via STM32CubeIDE for STM32F469I Discovery Board
Hello everyone,I am currently developing a GUI for the STM32F469I Discovery Board using the TouchGFX IDE. The GUI works perfectly when updated through the TouchGFX IDE.However, when I attempt to update the same project using STM32CubeIDE, I encounter...
Resolved! USB XACT_ERROR response on BulkIn request
Hi all,we are developing a board based on STM32F429 chip.In particular I'm developing a composite USB device on USB OTG port, showing a custom device + a CDC device [ep 0x85, 0x06, 0x83] using USB_Device_Library code.Windows correctly shows 3 items: ...
