Which code in SRAM4 for LPBAM?

Hello,In the example projects for LPBAM from ST, it is necessary to switch the RAM address to the SRAM region. This is because LPDMA has in Stop2-Mode only access to SRAM4.If I also want to use the RAM, which part of LPBAM (or maybe other parts) must...

STM32H755_CM7 and STM32H755_CM7 svd files v1.9 missing MPU and NVIC peripherals

I'm in the process of generating the Rust PAC for the STM32H755 using the svd files. I've downloaded the latest svd file v1.9 from here stm32h7-svd.zip I noticed that the file is incomplete as the MPU and NVIC peripherals are missing for both the CM7...

Resolved! TCPP03-M20 + STM32 - enable USB bootloader in dead battery mode

Hi,i am using STM32G0B1KB and the UCPD peripherals to implement an USB-PD device with 2 ports:- Port 1 is DRP & DRD device, USB FS data via STM32 USB peripheral, using TCPP03-M20.- Port 2 is Source only, not USB data capable, using TCPP02-M18.For por...

Resolved! UCPD (USB-PD) use DBCC pins for something else if dead-battery not needed?

Hi,i am using STM32G0B1KB and the UCPD peripherals to implement an USB-PD device with 2 ports:- Port 1 is DRP- Port 2 is Source onlyI need the dead battery pulldowns for port 1, so I will connect the UCPD1_DBCCx pins with the UCPD1_CCx pins as descri...

STM32F103C8T6 pin multiplexing problem

hello,STM32F103C8T6 enables SPI1, but does not use MISO pin (PA6), can this pin reuse other functions? For example, timer function.Also, the PWM output can be observed in the software simulation, but there is no PWM output in the actual test. Is ther...

Cannot get CC1 on TIM15 to go low using CCMR1 register

Using a Nucleo-F072RB. I am trying to get the output of CC1 to go low after the CPU does something. Everything is working as expected except I cannot get the line to go low. I have tried both variants of the CC1P bit and neither seems to work. I ...

PSRAM Issue with STM32L4R9 Discovery Kit

Hi,Currently I am working with STM32L4R9 Discovery kit. The connected PSRAM model with this board is IS66WV1M16EBLL-55BLI. Using HAL functions, I can only write and read up to 16 bit data (i.e. unsigned integer 8 bit (uint8_t) and uint16_t). Other da...

STM32F103RB I2C1 Busy Flag stays high when initializing

I finished my I2C peripheral drivers and I would like to test it with my bh1750 sensor but I am having an issue, when i initialize the I2C1 peripheral, everything is smooth but then I notice that the busy flag is always high and it does not go low, s...

Resolved! STM32F401RE SPI1 CLK signal wrong

I am trying to use the SPI example code, and I configured SPI1 on the NUCLEO-F401RE board in full Duplex work mode.I connected two NUCLEO-F401RE boards together by GND, CLK, MOSI, MISO,and CS(but I use NSS_Soft mode).Because there is no example code ...
