Hello.I implement the SD Card access using the SDMMC1 on the NUCLEO-H743ZI board + SD Card sub board.Now the SDMMC1 Interrupt was not occurred after the DMA request setting and SDMMC interrupt enable(DCRC, TIMEOUT, RXOVERR, DATAEND) for reading the M...
the ST-LINK can't detect the micro but the software who is already programmed in the micro work perfectly.Does anyone have an explanation why the reset breaks like this?
Hello everyone,I've been working with ST link v2 programmer/debugger for a while with IAR embedded workbench. But recently each time I start a debug session or I appoint a break point and I arrive at the breakpoint, the IDE freazes for a while and wa...
Hello everyone,I'm working on a projects that countains a stm32l152re to communicate with temperature/Humidity sensor amongst other sensors and a DC relay to control some light bulps. However, when the relay is closed, it overheat and corrupt the me...
Hello everyone.I am working on a project, where It has 6 PWM channels, and there will be 3 channels active at time, As all PWM channels must have the same frecuency, all PWMs channel must start and stop at the same time, I am trying to define TIM2 as...
Hi I have interfaced STM32L4 qspi with Winbond(W25N01GV). I am using HAL api's. The problem is erase/write to a page(2KB) address(say 0x0) repeats to the page after 512 KB(Say 0x80000) and so on. This is a 128 MiB NAND flash and erase command(D8h) o...
Hello All,I am facing an issue with the Driver for MT25QL512 Flash Memory within the STM32H750DK. I followed the MOOC provided by ST and did the same things but it still times out in the CSP_QSPI_Erase_Chip() during the QSPI_AutoPollingMemReady() cal...
