Setting up Keil MDK for DK nRF52832 SDK 15.2.0 ble_app_uart

[PAL_fujita]

Hi everyone,

I am a beginner for  BLE software development with MDK-LiteV 5.26.2.0.

• Target device: nRF52832（EKSHCNZWZ made by Taiyo Yuden）
• SDK: nrf5_SDK_15.2.0_9412b96
• SoftwareDevice: s132_nrf52_6.1.0
• Reference document: Attached

At first, I flashed the SoftwareDevice to the target device with the nRFgo Studio.

Verification was OK.

Next, I compiled according to the reference document and flashed it.

But it did not move.

Thank you for your help.

Hi, Berg-san

I  posted it again.
Can you see it?

Yes, thanks. The program reaches main(), which means that both app and Softdevice has been programmed correctly. Please try let the program run for a couple of seconds as well, then stop it and check if it ends up at the address shown in the screenshot below and not in the application's error handler.

Hi,Berg-san

Thank you for your reply.

I was taking a weekend holiday.

I set a break point and ran the program as shown below.

But my program did not stop at a break point.

I stopped at a different point.

Does this mean that an error occurred before the program reached the main()?

Best Regards,

The program ends up in the SDKs error handler meaning that there was an error after reaching main(). You can use the error handler to determine where the error occurred. 

1. Re-compile the project with the highlighted settings below for improved debugging experience

 

2. Step over the flash breakpoint 

3. Read out the error code, line number and file name to find out where and why the error occurred.  Common error codes are listed in nrf_error.h

Hi, Berg-san,

Thank you for your information.

I got the  evaluation license (No limitation, 30days) and continued debugging.

I saw the "0x00000004" of error code.

This seems to be an error related to memory.

I will continue investigating to resolve this error code.

Thank you for your supports.

Best regards,

Hi,

The error information indicates that the IRAM1 base is set too low (softdevice returns "no mem" error). Try with the settings below.

Hi, Berg-san

I tried the new memory setting.

Then I saw new error code(0x0000057D).

I examined the error code, but I idn't understand it.

What does it mean?

Best regards,

Hi,

This error is coming from the Softdevice. It can happen if you single step or halt the CPU after enabling the Softdevice since it has real-time requirements. Are you able to discover the device from your phone now?

Hi, Berg-san

Thank you for your reply.

I closed the debug mode, and I tried to find a device from my tablet.

It could not find the device.

If it can find the device, I will see "Nordic_UART" on it.

Best regards,
