I see numerous examples of 4-wire SWD without a reset pin connection.I come from the PIC world where there is always Data, Clock and Reset for a Pgm/Dbg interface.I bought a Chinese STLink-V2 programmer/debugger and it has a reset pin as well as data...
Hi,today I got my STLINKV3-MINIE and I quite like the polarized 14-pin Flat ribbon connector that is used on it.I searched a bit, but could not find this exact type of connector this is: Does anybody know what make and model this is?Thanks!Oh, and wh...
Is it a problem to set the constant of the external pull-up resistor connected to the "PB9_Boot0" signal to 100kΩ? (R13)Also, if there is a problem with the connection, I would like you to point out the relevant part.
I would like to use the STM32F779AI, in WLCSP package. I did not find any application notes, or schematics or dev board for such MCU. Is there some litterature or example, schematics, ... talking about layout rules, VIAs, etc... for the WLCSP-180 (p...
On the board schematics the LED is just connected to PJ2.I configured pin PJ2 as GPIO output push-pull, state high. So it should be off. But after roughly 1 second from reset the LED turns on and blinks like every 20 seconds.It's supposed to be user ...
Hello,for a first design verification i am using a NUCLEO-F429ZI board mounted on an own PCB.With my first board everything is fine and i have no issues. But with my second NUCLEO-F429ZI, the behaviour is strange.I am using the same PCB and can chang...
We have developed an application with legacy STM32F746G-DISCO.Recently we purchased more STM32F746G-DISCO.Although newly purchased STM32F746G-DISCO looks exactly same there are few changes as below-1 The color of leaflet is Yellow ( vs sky-blue )-2 C...
I have designed board with two USB. USB HS has to be device for the PC. Unfortunately it doesnt work connection's device descriptor request failed appears .I tried USB FS to be Device and it work fine. Is there any problem with the drivers for HS ...
I had PA13 and PA13 set as a GPIO. I was able to program it one time with both the ST-Link V2 Clone, a.k.a Blue Pill, and via the Bootloader program stm32flash (on SorceForge.net) using the UART.Both would only work on a new chip. Once the chip was...
I have multiple boards (self-designed) that I've been working with for years with no issue. However, suddenly I can't seem to do a Download/Debug (IAR compiler) using my ST-Link v2 (which I've literally used hundreds of times before). Tried a half do...
