Getting UART_ERROR_FRAMING issue

[Rakshita]

I am using Asynchronous API of uart to receive the data. During the reception I face UART_ERROR_FRAMING issue in UART_RX_STOP event. But after getting that too it enables the uart again and carry on with receiving the data but after sometime which is around 17-20min the data stops coming.
The baud rate is 9600 and is same for both the devices.

What can be the issue?
PLease suggest

Hello,

But after getting that too it enables the uart again

Are you doing this manually? If so, are you able to pinpoint why it doesn't happen after "17-20 minutes"?

Best regards,

Edvin

Actually currently this issue is solved but I am facing some different issue right now 
I am only receiving uart data and it comes after every 6sec and I store it in the sd card 
It runs smoothly till 5:30hrs but suddenly after 5:30hrs my code gets stuck in 

while (1) {

__WFE();

} after generating a hard fault 
I tried to debug step by step also but didn't find the issue because of which it was getting stuck 

For reference, I am attaching my code below

Actually I put a breakpoint in the WFE() function as I know that it always gets stuck in that 
In the call stack it was seen that after going through the hard fault it jumped to WFE()

In the logs I get nothing related to this it was very normal

Logs looks like this 

8168.build.zip

This is the build folder

How can I find the faulting instruction address in the build folder?

[Rakshita]

Did u get anything?

Hi, Edvin is out of office 

Edvin said:

Perhaps you can show what your hardfault looks like? Do you have any screenshots or logs?

I can not see any hard fault from the log you posted below. 

Also

If you have a logic analyzer I would follow the date connection and verify that everything looks okey at the moment when it stops receiving. 

If your device battery powered?

Thanks for your reply runsiv
This issue has been solved

[runsiv]

Glad to hear it
