nrf52832 reset continuously.

[1979]

Hi All Team Members,

Using Nordic Development Kit of nrf52832 I am able to write and test basic application using UART and BLE

using this kit I get the following error: 

I have load example code of ble uart from SDK 15.0 in Segger Embedded Studio to this kit but device reset continuously in debug and release both mode.

NRF_BREAKPOINT_COND;
// On assert, the system can only recover with a reset.

#ifndef DEBUG
NRF_LOG_WARNING("System reset");
NVIC_SystemReset();
#else
app_error_save_and_stop(id, pc, info);
#endif // DEBUG

please reply me the solution for device reset continuously in debug and release both mode.

Thanks and regards,

Ronak Jain

Hi,

Some error occurred (was detected) and caused the error handler to be run (which you have pasted some code for). You should be able to see more about what caused the error by building the Debug version (choose Debug instead of Release in the build configuration drop down menu) and running again. When you build with DEBUG the system will not reset but will instead trigger a breakpoint so that you can inspect the state with a debugger. In most cases the problem is that an APP_ERROR_CHECK has detected an error, and if so you can see the file name, line number and error code.

Hi,

Using Nordic Development Kit of nrf52832 and compiler Segger Embedded Studio for development.

Case 1: Build and Debug mode

Service named "Nordic UART"  found during  scan mode in Mobile APP. After connecting with this service, Data communication between board and BLE works ok in debug mode.

But when debug session stop and unplug device and plug it again than code not run. 

Case 2: Build and Run mode

After loading code through IDE or nrfgo  studio, code does not work. No service named "Nordic Uart" found during scan of device in Mobile app.

Reply me with solution for this issue. Thanks for your previous reply.

 Can you elaborate? Is it at this point you reach the error handler which you posted code snippets from in the initial question? If so, have you checked the state of the system and backtracked to see what proceeded this? Was it an error check?

Essentially this tells us that "it does not work". As already mentioned there is a need to use the debugger more to understand what is going on. I do not see any way around it.
