Hi Team,As we are going to use RAM – IC CY62136EV30 (TSOP-44) in our new project with ST micro STM32F407ZG (LQFP-144).Do we need any impedance matching for 6-layer board?Can you please suggest the same. Crystal frequency we taken 16MHz for the MCU.Th...

I am having a custom board having STM32N657I0H3Q interfaced with quad flash MX25R6435FM2IL0. I am unable to access (both read and write) to the flash MX25R6435FM2IL0.I have attached Saleae capture (configured the flash in single mode only for Saleae ...
I am trying to create two phase-shifted PWM waves on an STM32L4 TIM1 using asymmetric mode. From what I understand, I have to:enable output on GPIO channels 1 and 3enable output compare 1,2,3,4 and output compare 1,2,3,4 as asymmetric PWM modeThen, I...
From the ES0335 errata there are two errata that look pretty significant for dual bank boot (which I'm planning to use as the basis of field firmware update):2.2.8 Dual-bank boot not working when the boot in flash memory is selected by BOOT0 pinDesc...
Hi,I am working on an application for the STM32N6 (using zephyr) that streams data from four SPI interfaces (SPI1, SPI2, SPI3 and SPI6) via Ethernet (UDP). I am using full-duplex SPI transfers and GPDMA1.Everything works fine up to SPI clock frequenc...
We are working on a bare-metal application using USBX on an STM32N657X0H3Q device.In CubeMX, we configured USB1_OTG_HS under Connectivity and enabled USBX in Middleware. However, when we execute the following function: static void MX_USB1_OTG_HS_P...
I am currently using STM32G0B1. I found that when using an active crystal oscillator, the STM32 fails to recognize my crystal oscillator, resulting in the HSERDY bit not being set.This is the configuration of my cubemx.Use an oscilloscope to check if...
Hello,I’m currently testing the CSI–DCMIPP interface on the Nucleo-N6 board. I’m following various examples, but the variable used in DCMIPP_Start (lcd_bg_buffer) is not receiving any data. Is there something I might have configured incorrectly?At th...
Hi,I’m working with the STM32F407VGTX and I am using GPIO PA4 as the SPI chip-select (CS) pin. In my GPIO initialization, I set the PUPDR register to configure PA4 with a pull-up, expecting the CS pin to remain HIGH when idle. However, I observe on m...
