Upgrading the firmware
The Power Profiler Kit (PPK) firmware on the nRF52832 SoC can be upgraded in either one of two ways.
Option 1
The nRF5x DK will enumerate as a mass storage device. To update the firmware of the PPK, make sure the COM
switch is set in the DK position, and drag and drop the HEX file to the "JLINK" drive.
Option 2
The necessary firmware is included in the PPK software package with the following naming convention:
PPK_XXX.HEX
, where the XXX is the version number.
In the following procedure, the nRF52 DK is used as a reference, but the nRF51 DK can also be used.
To be able to program the PPK, complete the following steps:
1.
The PPK needs to be connected to a SEGGER J-Link device. The nRF5x DK has the SEGGER J-Link built in
and can be used by connecting to a USB cable. Connect the PPK to the nRF5x DK. Make sure that the COM
switch is in the "DK" position. See
Figure 9: Current measurements on the nRF5x DK
on page 15.
2.
The nRFgo Studio is used to erase memory content or program the application HEX file onto the nRF52832
SoC on the PPK. Open the nRFgo Studio on your computer. In the
Device Manager
pane, select the
nRF52
development boards
.
3.
Select the correct SEGGER entry with the ID matching the nRF52 DK connected to the PPK.
4.
Click the
Erase all
button to clear everything in the flash memory.
5.
Select the
Program Application
tab. Click
Browse...
to navigate to and select the HEX file to program.
6.
Deselect the option
Lock entire chip from readback
.
7.
Click
Program
, which will program the HEX file onto the selected chip.
