Timer issue with getting external flash binding

Sorry, but what exactly did you do to get it working? Did you enable printing again or remove the printk statements in the device_get_binding() function? As I've only seen parts of your code the only thing I can think of is that the printk() statement is returning an error because it's not recognized/included in your project when you have disabled PrintK.

Best regards,

Hello Simonr,

Yeah seems this is the case:

[quote userid="75734" url="~/f/nordic-q-a/91197/timer-issue-with-getting-external-flash-binding/382988"]If you're calling multiple printk functions in your application after disabling the printk that is likely to cause issues. [/quote]

Not altogether.

[quote userid="75734" url="~/f/nordic-q-a/91197/timer-issue-with-getting-external-flash-binding/382988"]Is there a reason you have printk() function(s) if your plan is to disable printk altogether?[/quote]

Anyways, Now it is working, I am able to get device binding for serial flash.

Help me understand how disabling print posed problems in getting device binding for serial flash..?

Thanks,

Ubaid

Hello Simonr,

[quote userid="75734" url="~/f/nordic-q-a/91197/timer-issue-with-getting-external-flash-binding/382811"]And what do you mean by[/quote]

What I mean is, as in printk definition below:

I added a return statement on line number 1 in the above definition.

So the revised definition of printk applies everywhere.

Now with this revised definition, the device_get_binding() returns 19.

What version of NCS are you using here? And what do you mean by "if I am removing return statement from printk(), the device_get_binding() returns 0"? Is the device_get_binding successful if you're not adding these printk() functions?

Best regards,

Simon

Hello Simonr,

I am using device_get_binding() function, in a C++ application file as:

Here I device_get_binding() is returning 19, if in printk() definition I am calling return; as soon as execution enters printk().

If I am removing return statement from printk(), the device_get_binding() returns 0.

In what file and code line does your application call the device_get_binding() function? This function iterates through the devices on the system. If a device with the given name field is found, and that device initialized successfully at boot time, this function returns a pointer to the device. To debug, it's best to set a breakpoint on your device driver's init function. Perhaps there is something in your application requiring printk. Is it the same call both if you enable and disable printk? Error 19 points to there being "no such device".

What nRF Connect SDK version are you using, and is your project based on one of our samples?

Best regards,

Simon
