@dave75

I imported a project that I've been working on in Keil MDK into Segger, followed the steps and all seems to go well except that the linker barfs on the arm_math library (CMSIS-DSP).

I get this:

undefined reference to arm_negate_q31' undefined reference toarm_float_to_q31' undefined reference to `arm_fir_interpolate_init_q31'

I went through similar trouble as you did with the Linker. But you basically need to state the corresponding math library file explicitly, as far as I know, so the linker knows it exists.

Goto Project->Edit Options...->Linker(under Code)->Additional Input Files: Include: $(PackagesDir)/CMSIS_4/CMSIS/Lib/GCC/libarm_cortexXXlf_math.a

Hope you already had this figured out by now.

I was curious to know if there is a guide/tutorial available yet for creating a brand new nRF5x project with SES without exporting an existing project from Keil or IAR. I work primarily on Mac and Linux and I am interested in learning how to create SES projects from scratch and adding the necessary libraries as needed, as opposed to working from a converted example. Thanks!

It seems to be some new changes in v3 of the Segger embedded studio so that this walk-through is no longer valid for the most resent version of SES. I am experiencing the same problem as embedded-creations.

The problem seems to be the that SES does not set some include paths for the prepsosessor. I am including them manually now and keep you posted about the progress.

EDIT: got it compiling see my blogpost devzone.nordicsemi.com/.../

Did anyone get it to work with the Preview DK, SDK12.0.0, and SES 3.10a? I'm close but I get no memory errors when initializing the stack and softdevice.

Has anyone tried using SES V3 to compile NRF5 SDK Examples? I tried using this tutorial with SES V3.10a and there's no "Project Template Chooser" window during import. The imported project is missing CMSIS files and build fails because it can't find "nrf_gpio.h" (and probably other files past that).

I posted about this on the Segger forum.

I have Keil project and want to migrate it to SEGGER Embedded Studio.

I followed instructions shown above.

However, when I tried to "Build" -> "Build and Run", an error occured. error says

my momery settings are,

<!DOCTYPE Board_Memory_Definition_File>
 <root name="nRF51822_xxAC">
  <MemorySegment name="FLASH" start="0x18000" size="0x28000" access="ReadOnly" />
  <MemorySegment name="RAM" start="0x20002000" size="0x6000" access="Read/Write" />
</root>

these are the same as in Keil project setting shown below.

Could you please give me any clue to solve this issue? Thanks in advance.

I am having the same issue as alhay49. After following the directions meticulously, the ble_app_hrs project builds fine but when trying to debug - I get the "Cannot download multiple load files because they overlap" error.

board: nrf52 PCA10040 (not preview DK)
SDK: nRF5_SDK_11.0.0_89a8197
SoftDevice s132
SES V2.20
Windows 10

UPDATE: I managed to solve this issue by following Wayne's suggestion:

"Go to "Project Properties -> Linker -> Linker Options" and in "Section Placement Macros" set FLASH_START=0x1C000 RAM_START=0x20002080 These values came from the armgcc build settings of the same HRS project, namely examples/ble_peripheral/ble_app_hrs/pca10040/s132/armgcc/ble_app_hrs_gcc_nrf52.ld "

Thanks Wayne!

Hi, I followed along with the directions with the ble_app_hrs but for some reason I get a "Cannot download multiple load files because they overlap" The only additional load file is the softdevice. Anyone else have this problem? Thanks

Hi, I've been trying to run proximity example without success. The example runs on PCA100028, but hard-faults immediately after connect. Double-checked everything. Unfortunately I can't run the same example through Keil as the code exceeds 32k limit.

Any help much appreciated.

No luck, just getting four always-on LEDs on my nRF52 DK :( I've set FLASH_START=0x1C000 and RAM_START=0x20001f00 to the values shown in the s13x_nrf5x_2.0.0_migration_document.pdf. Heap/Stack is set to 256/2048 Bytes and the memory map says FLASH start="0x00000000" size="0x00080000" and RAM start="0x20000000" size="0x8000". Memory usage looks like this:

There must've been something I've missed >_>

EDIT: Solved by changing ram start in linker options to 0x20002080.

Hi and thanks for a great article!

I am trying to run hrs example on PCA100028 with s130 softdevice and was able to perform all the steps without errors, and the board seems to be successfully programmed. But while the debugger shows program running, the nRF51 status LEDs stay always on, and I can't connect to the board - nRF Toolbox doesn't find any device. I double-checked all the steps in the tutorial, and even started from a vanilla SDK11.0.0, with same result.

I'd be grateful for any ideas what might be wrong.

After installation and import the SDK sample, cannot find the linker when open project option page. any idea?

Kan.

Thanks for the info on this development option. Do you know what kind of restrictions there are with respect to the free license? Eval only? Non-profit? etc.?

Thank you for the tutorial!

I wasn't able to get this to work on using the following

s130 soft device
the characteristic tutorial code found here github.com/.../CompletedCode
nRF51-DK

My error is this... Programming failed @ address 0x00000000 (block verification error) Verification failed @ address 0x00000000 Failed to download application. Error during verification phase. Please check J-Link and target connection.

My target connection is J-Link...

Any assistance would be much appreciated!!
