I have a main board with an STM32 uC which communicate with multiple STM32 uC daugtherboards over SPI. I currently use standard male pin headers on the top of the main board, and female socket connectors on the bottom of each daughterboard. The re...
Dear all, I'm facing the firmware downloading on a custom board for the first time after its testing version was produced. This custom board design was an heritance from an externarl designer but I have found some hardware issues that must be fixed....
Try to connect the receiving terminal of the external interface connection terminal to GND. Will this help with program changing issues?
Hello,I am preparing a custom board and I am preparing the portion of the board to program and live debug it. I have been looking at the evaluation board schematic and some other online references and I'm getting some contradicting information, so I ...
have tried with STLink V2 and it's works fine. In the manual of ST-Link V3 they are not specifying any particular jumper settings for SWD. With a multimeter I cannot detect Vcc of 3.3V between the VCC and GND of SWD pins. Please find the below pictur...
Hello.We are working on a project that uses STM32H747 dual-core MCU.Debugging does not work well when downloading to the latest version.So I'm looking for the V2.J32.S7 firmware that I used before.Currently, the downloadable version is J36 or later.I...
Hello,The STM32F7 supports up to two external SDRAM ICs, where both SDRAM ICs basically share the same set of pins. Given all the restrictions on creating traces between STM32 and SDRAM (different layers, same length, same number of vias, ...), how...
I read on the intenet that they both are used to debug the IC.But how they differ?thanks
