SWD Error while trying to upload any program on BLE Nano

Hi,

I was able to update the firmware as described on the website. But I am unable to upload any program. When I do that I get a failed.txt file with content "SWD Error". My connections between BLE Nano and MK20 are correct. I tried to do upload nrf51822_blinky_nrf51822_.hex the issue occoured. When does this error occour? what can be the problem?

Question relating to:

Last updated: 27 Aug 2020
BLE Nano is the smallest Bluetooth 4.1 Low Energy (BLE) development board in the market. The core is Nordic nRF51822 (an ARM Cortex-M0 SoC plus BLE capability) running at 16MHz …

Updating the firmware (https://developer.mbed.org/platforms/RedBearLab-BLE-Nano/) and fixing the connections (soldering) fixed the problem. I don't know which one was actually the solution.
