Failed to enable SWV.
Hi, I use an stm32f429 discovery board to examine some exercises.When I enter debug mode, SWV error message appears.That message appears today, not until yesterday, but I didn't change any settings.error messageFailed to enable SWV.SWV will be disabl...
STM32U5 series has no FMC SDRAM controller
After finding that the stm32u5 series seemed perfect for my application I discovered it does not have an FMC SDRAM controller.This leaves me in a strange position for my application where the stm32h5 doesn't have HS USB and the stm32u5 doesn't have a...
STM32F405 RGT6 CAN bootloader can't connect via STLINK-V3SET with bootloader V3.1
Hi,Currently we are using STM32 CAN bootloader to program the flash. All was fine until we use this batch of STM32F405 RGT6 with bootloader ID V3.1.We can not even use STLINK-V3SET and stm32cubeprogrammer to get communicate to this batch of chip. Rea...
Resolved! Struggling with I2C and the MCP79410 real time clock protocol
Hi, I need to use the MCP79410 rtc (or alikes: DS1307, PCF8583, etc) but the STM32CubeIDE I2C seems that can't handle the read/write protocol for these devices. For example, as the below image shows, one needs to send the control byte (writing) follo...
Rebroadcasting existing CAN msg on network issue
I'm working with an existing CAN network on which I want to read a msg, modify it slightly and rebroadcast.I'm running into an issue where the code seems to crash/freeze if I broadcast the new message too close to the original one thats on the networ...
The QUADSPI module sent extra one clock to get data
When I sent an SPI commnad to get the status from an SPI NAND, an extra clock was sent by the STM32F4.I chedked the waveform with a logic analyzer.An 8-bit command was sent to D0.An 8-bit address was sent to D0.There were 9 clocks sent by the control...
Recovering STM32H563 from closed product_state
Hey community, I was working on some production scripts for our H5 based boards and got myself locked out.This occured after trying to set the obk file. STM32_Programmer_CLI -c port=SWD ap=1 -sdp=<wrong_obk_path> I got a corresponding warning "Error:...
GPIO mode change
Hi, I set it to GPIO Input mode and am using it. When I receive any signal during MCU operation, I want to convert it to Input -> EXTI mode. I wrote these codes at the moment, but there seems to be a problem. My Init code : GPIO_InitStruct.Pin = ...
stm32f072rbt6 discovery board spi issue
Hello everyone,I am working with the STM32F072RBT6 Discovery board, where the board is configured as an SPI slave while another device acts as the master. I am utilizing DMA to receive and transmit data through two SPI interfaces (SPI1 and SPI2).Curr...
