Dear readers,
I'm trying to get blinky to work on the DA14580DEVKT-B but the jlink device does not seem to get connection with the DA14580 core.
Ive tried all the tooling that has been described in the guides and the result seems the same whichever tool I use.
When connecting using JCommander I get some error info:
For connecting the jumpers on the Devkit I used the schematics on the silkscreen.
UART connection on the first screenshot and SPI on the second.
Ive tried both connections with both the JTAG and SWD interface option.
also i noticed the following:
Power on target is said to be of. Executing the command: Power on, changes nothing.
I measured the testpoints on the board.
When connected with jumpers on SPI setting
TP6 = 1.50V
TP2 = 80mV
TP11 = 60mV
SPI_SUP = 3.4V
经颅磁刺激= 3.32 v
TCK = 1.48V
connections on J6 are 0V
When connected with jumpers on UART settings.
TP6,2 and 11 = same as above
J4 P0_4 = 720mV
P0_5 = 720mV
P0_6 = 80mV
P0_7 = 80mV
经颅磁刺激= 3.32 v
TCK = 1.48V
The DA14580 seems to be completely dead but i was able to program the flash memory and burn the OTP before.
I hope any of you guys can help me out with this problem.
If you have any questions or want me to test any specific connections or signals please let me know
Kind regards, Jack
I've made some pictures of the hardware connection:

Also i've tried to connect with JCommander, and other tools, withthe power jumper on both INT and BAT setting.
Voltage levels in both jumper settings seem allright
Hi bgroffen,
In the device manager of your windows system can you see that the drivers of the jlink are correctly installed (you should see a Jlink CDC UART Port under your system ports) ? Have you tried to download the blinky code using the keil tool, can keil see your device? The fact that you could program the flash on the dev kit (what interface you used JTAG or the UART ?) Indicates that the dev kit (at least the 580) is ok.
Thanks MT_dialog
