Hi,we are currently evaluate the STM32MP for a project and we want to ensure that we can handle all errataissues that concern our usage scenario.In Errata are the points: 2.6.1 to 2.6.4 that discribe DMAMUX issues. At this point my question is:Does L...
Hello guys.I am proceeding in the manner provided on the WIKI page(https://wiki.st.com/stm32mpu/wiki/STM32MP1_Distribution_Package).However, the following problems still occur in Step 6.[error codes]-----------------------------------------------...

Hi,i try to use a ADM DMA with the board in object.I generate the code with CUBE MX and i add only the function HAL_ADC_Start_DMA(&hadc1, (uint32_t*)&buff, 1); before the while loop in the main.After i start the ADC, the hadc1.State remains in HAL_A...
