Variable "sec_mode" is used uninitialized at this location in the sourcecode

[Renix]

With IAR (EWARM) 8.50.9 the UART project in the SDK compiles fine.

After upgrading to IAR (EWARM) 9.10.1 or 9.10.2 I get compiler error:

 Error[Go029]: Variable "sec_mode" is used uninitialized at this location in the sourcecode. D:\2\IAR\nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_uart\main.c 156 

Any help on what the problem is?

Hello,

Error[Go029]: Variable "sec_mode" is used uninitialized at this location in the sourcecode.

This is a common compiler error, and it says that you are using the sec_mode variable, without having initialized it - so it may be any random value at the time of use.
Please look at the mentioned line 156 of your main.c. Make sure that the sec_mode variable is initialized before it is passed to a function.
Please see this stack overflow ticket for more information about why you almost always should initialize your variables.

If this is not the solution to your problem, please share the entire function which encompasses line 156 of your main.c file. Please use the Insert -> Code option when sharing code here on DevZone.

Best regards,
Karl
