Resolved! Unwanted received byte at startup with UART+DMA

Hello ST experts,I have a weird experience with UART communication between two STM32G4 microcontrollers. MCU1 sends 10 bytes to MCU2 via UART. Both UARTS are configured with 9600 Baud rate with DMA in circular mode. The Problem arises when the MCU1 i...

Need information related to the H.264 encoding

Hello,I am using the VENC_RTSP_Server example located in:STM32Cube\Repository\STM32Cube_FW_N6_V1.2.0\Projects\STM32N6570-DK\Applications\VENCThis example shows how to use the VENC block and stream H.264 video through RTP/RTSP using Ethernet.I want to...

STM32G474RBT6 DMA question

Hi, everyoneI recently encountered a strange phenomenon. I opened three DMA channels on the STM32G474RBT6.The first one is Channel 1 of DMA1 (circular mode), which is used for automatically collecting the data converted by ADC.The second one is chann...

Resolved! Cortex M0 Vector Table Reallocation Problem

In my embedded software project, I need to write a bootloader. I wrote an application code for the bootloader and testing, and everything is fine so far, but the delay function in the application code is not working. I think the reason for this is th...

Resolved! Writing to the FLASH_OPTR to switch banks

I am designing a system that will utilize the dual bank feature of the STM32 devices to make a robust system for OTA updates. I am currently using a STM32U545 for my project and have questions about writing to the FLASH_OPTR to change the SWAP_BANK b...

RM0394 SRAM2 connectivity in bus matrix

In the lower-end STM32L4, covered by RM0394, SRAM is partitioned into two parts, SRAM1 and SRAM2.SRAM2 (besides being "special" in that it has ECC and automatic erase facities), is mapped at both 0x1000'0000 and at the end of SRAM1 in the 0x200x'xxxx...
