I have a custom STM32 Board that is supposed to act as a flight computer. Currently I am having trouble connecting to the STM32F4 chip over SWD.I am using a STLinkV3.I can read the following voltages:Vdd = 2.4VVda = 3.3VBoot0 = 2.4VBoot1 = GNDNRST 2....

HI!I am trying to program a custom STM32F446 Board using the SWD connections on the board. When trying to flash the custom board I receive the following error on OpenOcd: xPack Open On-Chip Debugger 0.12.0+dev-01312-g18281b0c4-dirty (2023-09-04-22:...

So I have a abstracted function to read the INA226 component. The function reads the data completely fine over I2C. The problem occurs when I try to display the read data on my dev terminal (Terra Term) over the COM port for STM32. The output on the ...

Hi!I am somewhat unclear on how to handle variable length transmissions using the STM32F4xx HAL. I have looked at other solutions, and suggestions have been made to use HAL_UARTEx_ReceiveToIdle_DMA() or the ISR equivalent.My situation however, involv...

Currently I am trying to interface with a LM75A temperature sensor using the STM32F446RE nucleo board.From the datasheet of the LM75A, I gathered that the sensor, returns a temperature measurement without any configuration.So I tried to simply hook u...

I wanted to use the System Memory when configuring the bootloader, is there a particular reason that would be a bad idea when connecting over SWD?I have a way to set the Boot0 pin to low using one of the switches. So I will try that!

NRST is getting voltage (~3.3V) so its driven highThe STM32 Chip also has a constant 3.3V on the VDD.Cant figure out why the OpenOCD or STM32CubeIde cant find target.

I added an external source, and tried again but this time the init failed:Heres the error message:xPack Open On-Chip Debugger 0.12.0+dev-01312-g18281b0c4-dirty (2023-09-04-22:32) Licensed under GNU GPL v2 For bug reports, read http://openocd....

I might be the dumbest person alive (atleast from what I have read online  ) You need to provide the STM32 with your own external power, the STlink SWD Vcc connection doesnt power the board itself!

Dont think the CMSIS memset uses the STM32 DMA, but I might be wrong there. Also ty for the webpage, will look into it!!
