Resolved! UDP packets no sent on certain ports
Why are UDP packets on port 53600 sometimes sent and visible in Wireshark, but at other times they are not sent? What factors could influence the intermittent transmission of these packets?

Self waking up from Standby Mode
HalloI use STM32F779 and want to enter this device in Standby mode and wake up via Wake up pin (PA0). The problem is that everything only works one time correctly or it complete its loop first time just correctly. After the Reset, Microcontroller goe...
UART via DMA remains busy
HelloI am currently working on a project needing UART via DMA, however when trying to transmit something via this UART nothing is received on the receiving end and the UART remains in HAL_UART_STATE_BUSY_TX.I am also making use of ARM TrustZone.USART...
Resolved! STM32H563 bootloader SPI configuration
Hi,in AN2606 rev 64, I cannot find the SPI settings for STM32H563 bootloader, i e CPOL, CPHA etc. For the other MCU:s in this document, this information is provided.For example H72xxx comes with CPOL = CPHA = low.Using these settings, and a rather sl...
Resolved! Identical PWM output setting behave differently on General and Advanced timer at duty 0
Hi!The PWM signals are identical and work as normal except when HAL_TIM_PWM_Stop (or HAL_TIM_PWM_Start) is called at duty 0. The Advanced timer work as expected and cause the output PWM to go low, while both PWM signals go low for the General timer....
Resolved! ISSUE WITH DSI MIPI ADAPTIVE COMMAND MODE HP TRANSMISSION
I am currently working with the STM32U5G9J-DK1 development kit interfacing with a Tianma-based display. I have successfully managed to update the display using adaptive command mode with DSI long and short write commands. However, I am encountering i...
Resolved! 4 line Nor flash speed during memory map mode
Hi I use STM32H743XI and W25Q256 for my design.And I notice W25Q256 has two speed 133Mhz(W25Q256JV) and 104Mhz(W25Q256FV), currently I use W25Q256FV, since I only use this flash with memory map mode, is it necessary to replace with W25Q256JV? Will th...
STM32 for high speed ADC > 100 MSPS
Hi,My customer wants to design a high speed ADC aquisition system with minimum 100 MSPS rate and 14-bit resolution.The external ADC devices like AD9258 and AD9268 have this capability, which we are proposing.Would it be possible to use a high speed S...
Resolved! STM32 for live streaming
Hi,we would like to add live video playing/streaming to an STM32-based board we are designing that uses MIPI-DSI to drive a touch display, and we are at the stage of choosing the micro.Ideally it would stream from HDMI signal but we can use another i...
Resolved! H723Z external SD Ram clock no signal IS42S16400J-6TL
I'm working on a custom board with a STM32H723ZG. I'm also using external sd ram part IS42S16400J-6TL found here (https://www.digikey.com/en/products/detail/issi-integrated-silicon-solution-inc/IS42S16400J-6TL/2708625). I've followed the excellent s...
