Hello!For a redesign of an already existing product we're using an STM32H743XI, which is a TFBGA240+25.The BGA balls "B6" and "F2" are documented in two different ways in the datasheet and in CubeMX, see also attached picture.Datasheet "DS12110" (ver...
Hi, I would like to use the STM32F746G-DISCO to do a project. But the pins available on it are quite few (only PA0-PA5 and PD0-PD15). I wonder if those pins' function are fixed because I only succeeded to use PA0 as PWM Output of TIM5. It seems like...
Hello,i am using the ST-LINK Utility 'Serial Wire Viewer' for debbuging three MCU, which are communicating to each other. For a fast opening and exact placement of the windows i use my autohotkey script. Everything work fine, but now i want to set th...
The schematic and insert card disagree.The VCP is USART3 PB10/PB11 (verified)The Arduino header D0/D1 is PB7/PB6 USART1UM2488 described in the data brief is also missinghttps://www.st.com/resource/en/user_manual/DM00547983.pdfhttps://www.st.com/resou...
On the STLINKV3 Mini, what is CN3 used for and what are the signals? Do the two reset pins have a useful user function?No information on this is available in the current user manual.Cheers, Hal
Hi,Some new nucleo STM32G4 boards have simplified version of the st-link v3 (no bridging feature implemented, at leat at the connector level, I guess).Is there any benefit from having 3e st-link version vs regular 2-1 one?
Communications appears fine; I get the following from BlueNRG-1 ST-LINK Utility (version 2.0.0.0):ST-LINK SN : 067......ST-LINK Firmware version: V2J33M25Conncetd via SWD.SWD Frequency = 100 KHz.Connection mode : Connect with Pre-Reset.Debug in Low P...
Nucleo-G474RE has JP7, which pulls down BOOT0 pin to ground when a jumper is installed, but this alone does not control boot options. What is the intended usage of JP7? Does it have something to do that Nucleo-G474RE comes with nSWBOOT0 option bit cl...
The STM32 ST-LINK V1 connects and recognizes the BlueNRG (see STLINK-V1)for the ST-LINK V2 and V3, the STM32 ST-LINK Utility connects but does recognize the device. same for the STMCubeIDE debug connection13:38:57 : ST-LINK SN : 56FF6D067878545241190...
