hiI have a question while set Option byte using STM32 ST-LINK Utility.I'm testing STM32H750 MCU (chip, socket EVK, ST-Link) After I set the Security bit using ST-Link Utility, MCU can't debug anymore. (like figure1)Is it right that setting Security b...
Dear all,I am using a NUCLEO-L4R5ZI board and am trying to get the octospi interface running in quad mode.After generating the code I tried to run the generated code in the STM32CubeIDE but failed to debug it. Since it seems that the system memory ge...
I have frozen my project on v1.6.1, for good reasons because I don't want new libraries; the existing ones are already massively bloated and full of bugs :)Have they fixed bugs likecannot delete the .elf file (the STLINK debugger is grabbing it - alr...
I wondering on which hardware configuration, I have to implement for this purpose.Could I just use the differential pair as in joined picture without VBUS (as the µC is supplier on Board)?I would like to get more details on how to design this interfa...
What about Vref+??As I am not using any Battery, I have decided to connect Vbat directly to VDD, is that correct?OSC32 will not be used in my app, will it be possible for to leave it open?
HiI am using STM32CUBEIDE on macOS. Until now I used my ST-Link v2 via SWD with no problems. I have recently upgraded to an ST-Link v3 MINI and implemented the STDC14 connector on my custom pcbs. The pinout is according to the datasheet (the pins on ...
According to the manual UM1956 I can power my Nucleo-L432K board using 7-12V on VIN.So I attached a 9V block to VIN and GND. It did not work, and all that happened was that I started to smell and got hot. It looks like the capacitor C25 was the compo...
I want to copy-paste ST-Link implementation from a Nucleo or Discovery board to my customer board with STM32H7 processor. This way, the board will have one USB connector to use for programming, debugging, upgrading, and finally, for serial communicat...
I join the schematic of my board to the question. I am unable to connect my custom board, the error message on STM32CubeProgrammer is "Not STM32 target found" even it detects the supply voltage. The VDD required for the MCU is 1.8V and I connect all ...
I am in the process of designing a new controller for a product and the only processors that seem available in any quantity are the -P versions. The datasheet isn't clear for these if the SMPS is optional and you can just use the internal LDO, or if ...
