Where can I find the datasheet for the IEG1120TB103GF-001 display on my 32L4R9IDISCOVERY? The only Google result shows a PDF that doesn't include the startup sequence, and the demo code has what seems to be completely arbitrary initialization sequenc...
Hello! The problem is ST-Link V3 not always connect to the target with ST-Link GDB Server. It can connect one time, but next ten times doesn't connect. Reboot the programmer or reboot target doesn't help. With OpenOCD - works great with the same cabe...
Hi All,My board is built on the STM32F746IG.Some time after the launch of the firmware (3 different firmware) access via SWD is unavailable.Stm32_Link_Utility reports:- Core is held in reset- Can not connect to target!..........Vnrst = 0.3 V, despite...
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?
