using st-link utility to see data in sdram of STM32F429ZI. loader problem. help

Hello. Please helping me with solving this problem.I used Truestudio to write data into external sdram.Now, I want to see the data in sdram by using st-link utility instead of the debuging system in truestudio itself. (because of Liveupdate system, i...

Voltage Drop from 3.3V to 1V on NRST Pin of STM32F070CBT6

I am using STM32F070CBT6. I am experiencing voltage drop on NRST Pin from 3.3V to 2V or 1V randomly for few milliseconds then it goes high to 3.3V. This drop comes randomly in every 2 to 3 minutes. My VDD is stable I checked the same on Oscilloscope...

When using the ST-LINK Utility, it doesn't connect to the Discovery card.

I'm using True Studio to compile a sample PWM program and using ST-LINK to program the device. It worked for the first 20 or so iterations but now it won't connect. It gives me this message:OK I go to settings and there is no where to select "Connect...

Is it possible to show SWO trace from cli with ST-LINK_CLI or some other tool?

I'm using ST-LINK_CLI to flash my STM32F427 and I'd like to start SWO tracing after flashing. Is there a (Windows) command line tool which can do this? Currently running Win7, ST-LINK CLI v3.4.0.0 and ST Link  FW: V2J33S7

Programming the STM32VLDISCOVERY board

Hello All,The project I'm working on requires an STM32100RBT, so I ordered the STM32VLDISCOVERY discovery board, which mounts it.I can't seem to work with it, apparently because it has an ST-Link V1, which seems to be deprecated, judging by how widel...

How can we read the ST-Link SN(Serial Number) from firmware? IS there a specific address location like the one for UID?

I want this development board. (which is not yet)

Your mockups have a weird property to grow in value. I think this is due to the huge number of electronic components on the PCB, literally for all occasions. It is good for study, and completely useless for use in real life. That is, after debugging ...

Why stm32 randomly stucks at HSE?

I just made a clock with 7-seg display and Stm32f030f4p6. Firstly i used 3.2768 HSE(high package) and 2x22pF caps. ​That's annoying, but uC randomly stucks displaying one digit(display is multiplexed, So whole uC is stopping). I was trying 1.5pF but ...
