Hello,let say that STM32H753 mCU has connected VBUS (via resistor divider to be sure that voltage on VBUS detection pin (PA9) would never exceed AMR), D-, D+ and GND lines with PC, before mCU core is supplied. At the moment when mCU core is then conn...
DMA stops working when I enable IWDG in .ioc on my STM32, even when commenting out the IWDG initialization for testing.DMA stops working when I enable IWDG in .ioc on my STM32, even when commenting out the IWDG initialization for testing.Before enabl...
Heyho,after some *** CAN beginner mistakes on my side, I got the FDCAN BRS 8 Mbit working.Or so I thought. It's only working between my custom boards, as I found out after connecting a Kvaser Leaf v3.With the Kvaser (directly connected to the board's...
I am using STM32WB55 and entering STOP2 mode for low-power operation.RTC Wakeup timer is configured, and the interrupt works correctly in RUN mode,but the MCU does not wake up from STOP2 mode when the RTC wakeup interrupt is expected.Configuration:- ...
In the above image (logic analyzer) , SPI in DMA was supposed to start at the end of high on the second signal, but it starts a bit later. (3rd signal CS of SPI, 4th signal SCLK)And the SPI was to supposed to be active at every period (the first sign...
If have read the RM0456 and could not found a detailed description.If I switch the option byte DUALBANK to 0 single-bank mode, what will happen if I access a address which is normally supposed to be in bank 2? Do I get a memory access error?So is my ...
I have two boards, both with the G473.I am using the ROM bootloader on SPI1. On one board, the bootloader works. On the other, it only responds with 0xA5 during the initialization sequence.The MCU can program and run if I load it through the SWD por...

Hello ST Community team,On the DS11532: The title of the Figure 20 should be changed to avoid any confusion between figure 20 and figure 21.Also, the note under figure1 is not really clear since the STM32F767 TFBGA216 for example is not compatible pi...
Hi, I do not have a lot of experience with the STM32. I used other processors in the past like the LCP1768. We developed a custom bootloader to be able the load a new firmware into the uProcessor. In our current case, the STM32G474 is connected by ...
