I have experienced this issue on STM32L4R and STM32U5. If debugging through STOP mode (with DBGMCU_CR_DBG_STOP set), the flash memory occasionally seems to read out garbage as the MCU is coming out of STOP mode. This typically causes the CPU to har...
Hello,I dug deeper into PSSI behavior, and and I observed unwanted behavior. From my point of view it is a bug.PSSI is configured as:OUTEN = 1 (transmit mode)CKPOL = 0 (outputs driven on rising edge, inputs sampled on falling edge)RDYPOL = 0 (0 at in...
When I'm enabling DMA and run the code, the debugger hangs at "SCB_EnableDCache();" even though the function is correctly excuting when I go step by step. Also as seen in the examples the problem gets solved when using a static declaration "static v...
Is it possible to DMA DCMI data to external SPI PSRAM (8MB)? I don't have enough pins to place SDRAM and wish to buffer Camera data.
Hello,I wrote a Boot program in flash to initialize sdram and copy the app program to run in sdram. The current state is able to jump and run normally, but the length of jump time seems to be positively correlated with the size of global variables in...
Hello, Just a quick question as I need confirmation :Using a STM32H7 ADC in a differential input mode, does this circuit work ? The output of the op-amp is Vout = G * (Vin[+] - Vin[-]) + 1.65 .Then the ADC output should be between :[0 - INT16_MAX] w...
I have a project running on my Stm32H7. I imported my ethernetif/lwip settings from the Stm32CubeH7 H723 lwip + freertos http server example, but made some small changes. For the most part in the most basic sense, the driver works and my board at lea...
Hello,Using the STM32CUBEPROGRAMMER v2.2.0 + the NUCLEO-N657X0-Q :I tried to set the OTP_124 -> HSLV_VDDIO3 bit to 1 but it did not suceed. First, I read the whole otp, put 1 in that field then press Write and it did not work, the OTP_124 stays at de...
Hi,I am using NCLEO-U385RG-Q running STM32u385. I created a project using the board selector. I configured I2C2 using STM32CubeIDE to run in fastmode at 400khz for PINs PA6/PB2 per schematics described in MB1841. My clock sources are all defaults...
I have developed software on the Nucleo-L433RC-P development board which uses the STM32L433RCT6P MCU (the P defines it has 2 x VDD12 pins for an external SMPS).However, I have designed a PCB that uses the STM32L433RCT6 (no VDD12 pins) but want to con...
