Hi,

Hi Miro,

I have tried this option and i cannot able to connect to DAP. I have tried to reset more than 100 times still i get the same error.

"Dap: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 8.1.0.00007)"

Thanks,

Best Regards,

Hi Miro,

Yes, i have tried all the resolutions from this E2E forum on this issue. I still cannot make the board running. While i apply the power to the board the led's itself not glowing. I am not sure whether the hardware is down.

Thanks,

Best Regards,

Note: The led's around the microcontroller are not flashing while power on. The blue led's are fine.

Hello,

The LEDs arround the MCU are user LEDs so it is not necessary to be ON.
