Resolved! [STM32H755ZIT6] DCMI to external SPI PSRAM
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.

Resolved! [STM32H7]I use BootRom to jump to sdram to run the program,but the jump from boot to app is slow
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...
Resolved! STM32H7 ADC differential mode, using Vref/2 as INN ?
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...
Resolved! Stm32h723 pbuf free assert, why are the ethernet drivers still broken?
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...
STM32N6 OTP
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...
I2C timing on STM32u385 Nucleo
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...
Resolved! Can I flash software to a development board that uses a slightly different MCU ?
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...
Resolved! Intermittent failure when entering Standby Mode
Hello,I'm encountering an issue while testing the Standby Mode on my device.Most of the time, the device enters and wakes from Standby Mode successfully. However, after repeated testing, it occasionally fails to enter the mode.What could be the poten...
Time taken to switch to VBAT from VDD by RTC for STM32F091VCT6
Hi,We are using STM32F091VCT6 in our application, however we are observing some instance of RTC losing time. We checked entire datasheet but were unable to figure out how much time the RTC takes to switch to VBAT after VDD falls below given threshold...
