Facing Ethernet Ping Issue using FreeRTOS for STM32F767.
I am using STM32F767 with LWIP and LAN8742 PHY.Ethernet initializes but I am facing Ping does not work reliably. This is the Schematic.

Problem: Bus Fault error when using ADC + DMA on STM32H747i with Zephyr OS
I'm trying to read ADC1 on channel 12 using ADC with DMA in a Zephyr OS environment, but I'm getting a BUS FAULT error when using the adc_read_async() API.This is my prj.conf fileCONFIG_LOG=y CONFIG_MAIN_STACK_SIZE=4096 CONFIG_ADC=y CONFIG_ADC_ASY...
STM32U5 ADC + TIM TRGO + DMA: repeated samples when reading ADC at 100us interval
I am using STM32U575 (MCLK = 160 MHz) with ADC1 in scan mode (4 channels).ADC conversions are triggered by TIM3 TRGO and results are transferred by DMA in circular mode.Continuous conversion is disabled.TIM3 is configured to trigger ADC every 100 us ...
48 bit SPI implementation
Hi there,I'm attempting to use an STM32 U5 device to interface with another device over SPI, and am trying to do it using 48 bit SPI frames supported by this device.An illustration of what I'm trying to accomplish is below, the key is to be able to t...
With STM32N6, are there any limitations to using the NPU RAM
On the STM32N6, half the ram is attached to this NPU RAM on it's own bus. Are there any downsides to using this ram for non neural net applications. Use case I would like to use the NPU ram for just frame buffers. From what i can tell the memo...
800 x 800 Display with STM32U5G9VJT6Q - possible?
Hi,we are trying to get a 800x800 display to work with the STM32U5G9VJT6Q, using either RGB888 or RGB565 in Video Mode (Burst).According to what we read it is definitely possible. Did we miss something?Could someone please confirm that is definitely ...
'U5 SBus-via-DCACHE1 connectivity
Is this connection real?I don't think so. DCACHE implementation subchapter says:The DCACHE1 is placed on Cortex®-M33 S-AHB bus, and caches only the external RAMmemory region (OCTOSPI, HSPI, and FMC), in the address range [0x6000 0000:0xAFFFFFFF] of t...
Resolved! What can keep the ADC from finishing a conversion? (STM32G474)
I am trying to complete one – just one – ADC conversion without using DMA. This is sort of a one-off sampling after power-on, and subsquently the regular sequence conversion with DMA is to take over. But I don't get that far.I'm trying to sample ADC1...
Use pin as both SPI MISO and GPIO/EXTI input
I use external ADC (slave) with pins with dual function. And when SPI don't work , on MISO pin can check and "end of conversion". This is when SPI pin NSS is high.So: can I activate pin first like SPI "alternative pin" (pin is input - MISO) and like...
ADC not working with PCLK / 4 ?
Hi, Im using STM32g0b1 ADC in continous mode.I am continously converting channels 0,1 and 2. Everything works perfect when clocking the ADC with PCLK/2.SYSCLOCK is 64MHzPCLK is 64MHz so ADCCLOCK is 32MHz.I get End-of-Conversion Interrupts correctly a...
