Hi all, I have a custom board and application using the mentioned MCU, when I use the "run" with the Release option on STM32CubeIDE and once I use the board alone the FW starts flawless as soon I power up. Now when I use the STM32CumeProgrammer to u...
Hello,I am working with an STM32G431K8T6and using the LL library to configure SPI in master mode.The issue is with the MISO pin (PB4).The pin is configured as SPI input, with no pull-up or pull-down.When PB4 is left unconnected, the voltage is measur...
Hi, I have been trying to implement a logic to flash the updated firmware on top of existing with established DFU mode and using stm32cubeprogrammer. Where I chosen bin file for flashing and I provided the starting address as well. For confirming I h...
I'm using STM32F429I-DISCO with external SDRAM and DMA2D to render graphics.CPU run at 180 MhzSdram 90mhzLtdc clock: 3mhzLcd : 240*320 color RGB565Issue:I use DMA2D to fill the screen, then on Transfer Complete interrupt, I trigger a second DMA2D to ...
Hi,I have a question regarding the backup SRAM in the STM32U5. The reference manual is not clear about this:On the one had, it mentions the following Which seems to indicate that it is possible to place the device in standby without powering SRAM2. H...
Hello,When using stop mode 3 with the stm32u5a9j chip, I noticed a unexpected behaviour when exiting stop mode 3.I have a device connected to the stm32 chip which wakes up the stm32 on rising edge on one of its pin ( GPIOA0 ). This interrupt can be t...
Hi, I'm using the STM32H753-NUCLEO Board for some SW development, and I'm having some issues with the SPI Handling.I'm attempting to transmit a single 16-bit data packet, however on the scope I'm transmitting two 16-bit data packets. When I change my...
HiI created a composite USB device with CDC and UVC classes using usbd. The device is detected, camera image streaming works, and data transfer via CDC (virtual serial port) also works. However, after a random time, communication on the CDC data out ...
I am using two NUCLEO-U385RG-Q boards for I3C communication — one configured as the Controller (Master) and the other as the Target (Slave). I am trying to implement an IBI event with Pending Read Notification, and would like to know whether it is po...
Hi everyone! I have a working project based on STM32F746 with LCD, Ethernet and SDRAM(IS42S16160J-6TL) and now we are moving it to STM32H753II. I set up a FMC controller and tested whole SDRAM region with 8, 16, and 32 bit access. I use GCC. During t...
