Resolved! STM32H7 JPEG encoding with DMA leaves empty space
I am encoding a 200x300 image using the JPEG codec available in the STM32H743. The input format is ARGB8888, with the input buffer having a size of 240000 bytes (200*300*4). As I do not know what the output size of the JPEG codec will be , I have all...
How to Reset an UART after an error
Hi,Recently, we desighed a test board with STM32F103RB for UART communication with a wireless chip, and we found that the HAL_UART_ErrorCallback is triggered occasionally (the periods of errors vary betweent tens of minutes to hundreds of minutes), t...
STM32U073 bug in SystemCoreClockUpdate()
I'm using STM32CubeMX 6.12.0, with the firmware package U0_V1.1.0.When generating code for a STM32U073, the file system_stm32u0xx.c is generated, which contains the implementation of the SystemCoreClockUpdate() function.This file seems to be a mere c...
STM32H743 memory bandwidth issues with DCMI, FMC, ADC, parallel bus, DMA1, DMA2 / DCACHE issue
I am developing a product which has an STM32H743 device. I am designing the firmware for the first PCBA prototype. The product receives 30fps video signal from an 720i analog video decoder through DCMI (every second bytes are stored, all lines, so 36...
