This section contains some common issues that may be encountered when using the USB-SWD programmer board and 
possible solutions for these problems. 

 

Problem 

The unit is connected to the computer and the red LED is on constantly, the green LED is not on. 

Possible Resolution 

Check if there is a NOLIC.TXT file in the virtual flash drive. If there is, please contact Laird 
Connectivity support with the details of this file. 

 

Problem 

Attempting to program or erase a module fails and does not work. 

Possible Resolution 

Check that the target device is correctly connected to the USB-SWD programmer board and that the 
voltage level is set correctly for the target (nRF51-based modules (BL600 and RM1xx) do not 
support writing/erasing flash at 1.8v and must be programmed at 3.3v).  

Check that the programmer is set to the correct device type. If automatic detection fails or has 
issues, set the programmer to force a specific module type by creating an empty file 

nrf51.cfg

 for 

nRF51-based modules or 

nrf52.cfg

 for nRF52-based modules. Copy it to the virtual flash drive, then 

retry the write/erase process. If this still fails, try reducing the maximum SWD clock speed by 
creating an empty file 

swd1mhz.cfg

 and copying it to the virtual flash drive then retrying the 

write/erase process again. 

 

Problem 

The MSD drive does not appear on the computer or is visible but is empty as if there is no disk 
inserted into it. 

Possible Resolution 

Try power cycling the USB-SWD programmer board and ensure the voltage level is set up correctly 
for your module. If you are using Windows 7, ensure that the MBED serial port driver is installed as 
described in the 

MBED Serial Port Driver (Windows 7 only) 

section. 

 

Problem 

Writing to or erasing nRF52 devices with a QSPI memory chip can be very slow and/or time out. 

Possible Resolution 

The QSPI chip fitted in the Pinnacle 100/MG100 can take between 1-3 minutes to perform a full 
erase.  

We do not recommend that you perform a full erase of the QSPI chip. Try disabling QSPI/SPI flash 
access by creating an empty file 

qspi_off.cfg

 and copying it to the virtual flash drive. This hould 

prevent use of the QSPI erase function. 

Note: 

This entirely disables QSPI support.
