Resolved! what's the meaning of the "SN",readed from "STM32 ST-link Utility"
what's the meaning of the "SN",readed from "STM32 ST-link Utility"I read the UID from the Flash addr 0x1FFFF7E8, i found out the SNis not the UID. please tell me where is the SN 'data from? tks
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 ...
ST-LINK/V2 to small SWD connector
HelloFamiliar with Kinetis of NXP, I start with the STM32.I am looking for the ST-LINK/V2 to program small Cortex M4, with a small connector (SWD). ST-LINK / V2 has a 20pins cord with a 2.54 pitch. I can not find how it should be used with a small SW...
Resolved! Not recognized on macOS
Hey.I just got the STLink V3SET today. I've connected it via usb to my MBP "15 running 10.14.4 (18E226) and the device is not recognized as an USB device. The PWR led is bright green, but COM is not lid I think (I only see a tiny green & red dot).lsb...
STM32CubeProgrammer 1.4.0 and STLINKV3 on linux
Hello,STM32CubeProgrammer 1.4.0 still does not see a STLINKV3 on linux.It this problem known?There is also a Java exception when the program is started:jar:file:/devel/STMicroelectronics/STM32Cube/STM32CubeProgrammer/bin/STM32CubeProgrammerLauncher!/...
NRST / Reset Pin in STM32H7 more ESD sensitive than in STM32F4?
Hi,I have a new PCB here which somehow has latch up problems on the NRST pin quite recently. Usually then the NRST pin would just have zero DC resistance (or typically 1 Ohm) to GND. And then of course also the oscillator (8MHz XTAL) will not start w...
Resolved! ST-LINK/V2-1 change type to STM32 Debug+VCP failed
My board is NUCLEO-H743ZI. I change the ST-LINK type from STM32 Debug+Mass storage+VCP to STM32 Debug+VCP.But after the change STM32CubeProgrammer can not detect the ST-LINK.It might be a hardware ID issue?The usb pid of STM32 Debug+Mass storage+VCP ...
External Loader in ST-LINK works very slowly. 66MB in 25 minutes.
Hello. I have writed external loaders for 2 flash memories: W25N01GV - 1Gb and GD25Q127C - 128Mb. They are working correctly but too slow. For example, programming 66MB of data take time about 25 minutes! That's horrible long. What can I do to make p...
