External flash loader program not working
I am trying to develop an st-link utility external spi flash loader using STM32F411RE and Winbond W25Q32. Mass erase, Read, Sector erase are working well but the program not working, the following errors are pop-up 1)Timeout during flash programming....
Resolved! STLink detects MCU but fails to flash
Circuit (programmer given by SAMTECH part) (zoom in to see):When I connect STLINK V3 Mini to program the STM32L4676RG MCU, it detects the chip without errors. However, when I try to flash, STLINK generates fail.text.Any idea what's happening?
Diagnose USB connection of STM32F103VCT6 custom board
I have made a custom board for STM32F103 VCT6 and have shared the schematics and PCB Layouts below. I had used a blue pill dev board of STM32F103C8T6 for my circuit which worked well. However my production board (with bigger MCU) has intermittent con...
STLINK-V3Mini and STM32G081KB, how to transfer code?
I have a STLINK-V3Mini and STM32G081KB, on the board I have 4 connector pins (VCC, SWDIO, SWCLK and GND). SWDIO is connected to PA13 and SWCLK to PA14, as standed in RM SW debug port pins. VCC is connected on 3.3V. On the other side, I took 4 pins (3...
Resolved! Use NUCLEO-H745ZI-Q on-board STLINK-V3 as external debugger
Greetings,I'm trying to use the STLINK-V3 debugger and programmer which is included on the NUCLEO-H745ZI-Q dev board to connect to external STM32. I have read https://community.st.com/s/question/0D53W00000OmiV6SAJ/nucleoh732zg-has-strange-new-stlink-...
Resolved! Error (no st-link detected) when I try to debug or run code on nucleo board with stm32ide and Mac
Hi I have an error when I try to debug my nucleo board L412KB on my Mac . I have the latest stm32ide. But when I try to debug I got this error No st-link detected. If I run a s’y-info —probe I got no result 0 device found. If I try to update stlink f...
ST Link V2 doesn't connect the target after 1~3 times firmware download.(STM32G071R8T6)
Hi.I want to use ST32G071R8T6 on my project.As a first step, I was testing my firmware on NUCLOE-G071RB (that connected indivisual st-link board).I was no problems and working well.However, on the board I made, it behaves abnormally.ST Link V2 does...
Resolved! What debug capabilities should I put on my proto board for STM32F373?
I'm designing a proto board for my application and can't use a discovery board since there isn't one for this chip. So I have to put debug capabilities on my board. However, I can't find documentation on how to hook it up to the processor once I've...
