Error while building 'nrf52-mpu-easydma-using-gpiote-and-registers' example

[Hanish Kataria]

I tried building 'pca10040' configuration of "nrf52-mpu-easydma-using-gpiote-and-registers" example from "https://github.com/Martinsbl/nrf5-mpu-examples". The following error comes while building the example. It also shows 'Build Completed' at the end but hex file is not getting generated.

Hi,

It is hard to see what the error says in your image, but it looks like the compiler tries to open a file, but the path to the file leads to a folder that is not included in the example in github. Can you put these project files in a zip-file and upload them, so I can try to compile it myself?

Hi Martin,

I extracted these projects in examples folder of SDK 14.2 and tried building "nrf5-ble-mpu-data-ready-interrupts" this example.7585.nrf5-mpu-examples-master.zip

I suggest that you try to import the Keil project files to SES using the built in "importer" in SES:

It seems like you have to manually add some include paths etc to make it work though. Unfortunately I don't have time to update the example.

Hi Martin,

The problem is solved and it is getting builded. But it is not giving any output on PUTTY, instead it is giving the following error

Can you tell me why this error is coming and how to resolve it?

What happens at line 131 in main.c? I bet the error is returned from a function that transfers data to the MPU? Can you double and triple check that you have wired everything correctly and that your MPU has power? If it doesn't work, can you try this example: TWI Scanner Example?

Hi Martin, 

MPU9250 was not working properly. The issue has been resolved. Thanks for your support.
