Hi,
i have a new EVLSERVO1 and a STLINK-V3SET ant try to program my MSDK 6.4.0 generated firmware but i am not able to connect to the bord.
I use the latest STMCubeProgrammer 2 20.0 and the latest stsw-link009 USB Driver.
I updated the Firmware on the V3 to the latest version. And i tried both variants of the firmware.
The Software recognizes the V3 Hardware and reads the 3.3 Volt from the ELSERVO1 board.
i tried to use a Win10 and a win 11 machine.
But I am not able to connect or to flash the Board.
The 14 pin cable to the board seams to be ok.
I am able to connect and flash other STM Boards with this setup like the STM32H745I-DISCO.
Is there anything I have to set to achieve a connection?
I also tried the UART1 connection with Tera Term without success.
Do I have to send the Bootloader activation patterns 15?
From the Manual:
Programming and debugging
The EVLSERVO1 provides a J1 connector to program firmware on the STSPIN32G4. The J1 provides STDC14 pinout featuring both SWD and UART interfaces that simplify communication with the PC through a virtual com port. One STLINK-V3SET debugger/programmer can be mated to J1 using its flat cable. The mating of this flat cable with J1 must be with the plastic notch toward the upper side.
Thx Thomas
