Hi.
Trying to set up the Ubuntu development environment for you nRF52 development kit.
I followed this tutorial: devzone.nordicsemi.com/.../
Stuff done so far:
- Installed latest gcc-arm-none-eab tools under /usr/local/
- installed 32 bit libraries(sudo apt-get install lib32z1 lib32ncurses5)
- installed the SDK (developer.nordicsemi.com/nRF52_SDK)
- changed the makefile.posix to: GNU_INSTALL_ROOT := /usr/local/gcc-arm-none-eabi-5_2-2015q4 GNU_VERSION := 5.2.1 GNU_PREFIX := arm-none-eabi
-Tested the build for blinky demo (success) -Tested the flashing in drag-and-drop-mode (success) -Installed the jlink (www.segger.com/jlink-software.html) Linux V5.10u, TGZ archive 64-bit version [13,715 kb]. I put it to /opt/SEGGER/JLink as it seems to be the hardcoded location in the SDK
At this phase I tried the old style flashing with /home/matti/Tools/nRF5x-Command-Line-Tools_8_3_0_Li nux-x86_64/nrfjprog/nrfjprog --family nRF52 --program _build/nrf52832_xxaa.hex
I get: ERROR: There is no debugger connected to the PC.
Also if I try to run /opt/SEGGER/JLink/JLinkGDBServer, I get: SEGGER J-Link GDB Server V5.10u Command Line Version
JLinkARM.dll V5.10u (DLL compiled Mar 17 2016 19:06:19)
-----GDB Server start settings----- GDBInit file: none GDB Server Listening port: 2331 SWO raw output listening port: 2332 Terminal I/O port: 2333 Accept remote connection: yes Generate logfile: off Verify download: off Init regs on start: off Silent mode: off Single run mode: off Target connection timeout: 0 ms ------J-Link related settings------ J-Link Host interface: USB J-Link script: none J-Link settings file: none ------Target related settings------ Target device: unspecified Target interface: JTAG Target interface speed: 1000kHz Target endian: little
Connecting to J-Link... Connecting to J-Link failed. Connected correctly? GDBServer will be closed... Shutting down... Could not connect to J-Link. Please check power, connection and settings.
If I check lsusb, I can see the the device there (and as said, drag'n'drop flashing works): Bus 001 Device 020: ID 1366:1015 SEGGER
also dmesg | SEGGER: PQ: 0 ANSI: 4 [4343271.361802] usb 1-2: Manufacturer: SEGGER [4343277.367831] scsi 11:0:0:0: Direct-Access SEGGER MSD Volume 1.00 PQ: 0 ANSI: 4
I can live with the drag and drop flashing, but the problem is that the eclipse debugging doesn't work either (test with the blinky example just like in the tutorial). There I get the same error as above: EGGER J-Link GDB Server V5.10u Command Line Version
JLinkARM.dll V5.10u (DLL compiled Mar 17 2016 19:06:19)

Ideas? Suggestions?
