Hi there,I have been struggling with the PSRAM. I bought the STM32H7S78 board to pick up the know-how to understand how I should configure the PSRAM at XSPI1 via the EXT MEM manager at my own board. My clock speed is 200MHZ XSPI. PSRAM MPN: APS6408L-...
I have a new board design that interfaces an STM32L4A6 with a uSD card using 1.8V I/O. The SD Card is powered by 3.3V and supports the LVS mode of SD. The STM32L4 does not seem take account the SD specification 6.0. There is no auto detection mecanis...
Is there a comprehensive single documentation source of the Flash layout for say, an STM32H563?The documentation I find is very opaque. Questions I have at present (From a non secure perspective):1. Where is OBK located? (0x0BF0000 to 0x0BF9FFFF ???...
Hello,I want to add a software update feature to my device, but I am unsure about the correct way to verify a newly installed firmware image. My goal is to make sure that the entire firmware has been written correctly and is not corrupted before the ...
Hi,I am getting a warning "The core is locked up" and a few more (please refer to the attached image).I have also tried flashing with the hex file, but some flashing issue is observed.
Hello!I am interfacing an ADS131M02 ADC to the STM32C0116-DK board using SPI for a project I am developing on live streamings. I am able to read SPI Data using the HAL polling functions (HAL_SPI_TransmitReceive), however that created unwanted delay b...
I am working on the NUCLEO-H755ZI-Q, which contains a dual-core STM32H755 (Cortex-M7 + Cortex-M4). I configure the system clocks in CubeMX as follows: SPI1/2/3 Clock MUX: 400 MHzSystem Clock: Configured for high-speed operationCM7 core frequency: Cor...
Hy,we are about to create a Proof-of-concept system for a camera application. We want to use STM32N6 Nucleo-144 board (MB1940) Board and add a extension board to CN2, CN3, CN15 and CN16. The project needs Ethernet (which we want to use from Nucleo Bo...
Sequent Microsystems designs and sells Automation Systems using Raspberry Pi. All our products use STM processors. We use about 10,000 processors per year in different configurations. Generally we do not have any quality problems, but occasionally we...
Bit-banding Alternatives for Modern ARM Cores Background Information: The bit-banding feature available in ARM Cortex-M cores (ARMv7-M architecture including Cortex-M3 and Cortex-M4) provides hardware-level mapping of individual bits within a 1 MB me...
