STM32G031 Discovery and Keil uVision
Hi there!i buy a STM32G031 Discovery Kit, i try to program with Keil uVison but gave me this error "No target connected" , i download the last version USB driver for STLINK but i have the same problem. Some one can help me ?Thank you Sergio
Resolved! STM32H7XX device security bit error
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...
Resolved! If octospi is enabled system memory is mapped at 0x00 after reset even thought flash should be mapped.
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...
What has changed in Cube IDE v1.7?
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 am planing to design a USB interface for programming purposes on STM32H743VIT6 as the bootloader is already integrated on the µC.
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...
Hello, I am designing my Hadrware base on STM32H743VI. Was looking for Power supply application note I could not find any. I would like to know how I would have to connect my VCAP as the LDO is not used or provided. Shall I put it on 100n??
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?
Resolved! ST-Link v3 Mini with STM32CubeIDE
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 ...
Resolved! 9V battery block as VIN for STM32L432KC Nucleo-32
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...
ST-Link implementation on a customer board
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...
