Hi,New to STM32 I'm discovering the STM32L072CZ, I'm trying to access the AHB2 bus by SWD interface in order to r/w on addresses (say 0x4800 0000 on peripheral GPIOA). When performing a coresight read on 0x48000000 I got 0xBC11477.After checking Ultr...
Status bits in the RCC internal clock source calibration register (RCC_ICSCR) indicate which clock(s) is (are) ready and which clock is currently used as a system clock.Should be the following:Status bits in the RCC clock control register (RCC_CR) in...
Hello all,In my design, I wish to use the STM32H725RGV6 (VFQFPN 68pin)In this package, there is no embedded LDO.There is no explanation or design example for the use the embedded SMPS in this package...should I connect the SMPS output directly to VCO...
Dear Team,We are using the STM32G473VET6 microcontroller with the IMP34DT05TR microphone, utilizing the serial audio interface with DMA.The current buffer size is set to 1000 samples. However, we are encountering an issue where only half of the buffe...
Hi all,we have a custom board with STM32H753 MCU and a DP83848 PHY. When configuring the PHY in loopback mode I can send and receive messages as expected. But when not in loopback mode we can receive data but the Tx path is not working.As the loopbac...
Hi everyone,We are currently designing a board which integrate a STM32L071Ux with UFQFPN32 pinout.In the pin description of this package, it is indicated that pin VDDIO2 supply PA11 and PA12.As we are not using some pins including PA11 and PA12, we ...
There seems to be conflicting information about FMC support on the STM32F446RE board. As the spec sheet says that it doesn't have support for FMC while the stm32f4 series product page says it has FMC. I have attached some files showing this contradic...
Currently I'm programming a smaller data collector which also opens some power FETs.My problem is, that the voltages I want to monitor are sent into a voltage divider so the Nucleo can sense it without any damege to it. For the voltage measurement I'...
Hi Team, Working on a custom design using STM32H750 and 2 Winbond W989D6DBGX6E LPSDR memory devices configured for 32b bus. The Design passes memory test at FMC_SDCLK@80Mhz.The Design fails memory test at FMC_SDCLK@100Mhz.When checking the signal tim...
Posted on October 03, 2017 at 17:53Hi,I'm having trouble getting SDIO to work on a STM32F767 based project. I used the exemple provided in the CubeMX repo to try a dummy read/write, but the initialization process stall in the SD_PowerON() function.A...
