In SDK 11 I have PSTORAGE_NUM_OF_PAGES in pstorage_platform.h. In SDK 9 you should have PSTORAGE_MAX_APPLICATIONS defined in pstorage_platform.h Try to increase it instead of PSTORAGE_NUM_OF_PAGES

Thank you Vladimir that was the problem! One question. In my set up in SDK 9 PSTORAGE_NUM_OF_PAGES is defined in pstorage.c which is kind of weird for a #define that may need modification. Is there a reason for this or should I just comment it out there and move it to pstorage_platform.h ? Thanks again!

eq You can get error during pstorage_register if you have only 1 pstorage page at your pstorage_platform.h and if your code and deviceManager are booth using pStorage. In my case changing PSTORAGE_NUM_OF_PAGES from 1 to 2 solved pstorage_register problem.

When I follow this example (remove the pstorage_init() function from init_p_storage()) I get : p_storage registration error during pstorage init. Also the example doesn't have this function:

//
	//  Get the Block Handle
	//
	retval = pstorage_block_identifier_get(&pstorage_handle, block_num, &p_block_handle);
	APP_ERROR_CHECK(retval);
	if (retval != NRF_SUCCESS)
	{
	   	printf("Error: %lu\n", retval);
	}

which seems to be needed to read and write as below:

err_code = pstorage_store(&p_block_handle, pstorage_buffer, block_size, block_offset);

err_code = pstorage_load(pstorage_buffer, &p_block_handle, 16, 0);

Should I not be using these calls to read and write to pstorage anymore? A bit confused... Do I no longer need the storage handle?

Thanks

yes, however, when i remove it from one or the other things break. The best question is: IS THERE AN SDK 9.0 EXAMPLE OF HOW TO USE THE DEVICE MANAGER ALONG WITH PSTORAGE. THIS IS THE PROBLEM THAT I CAN'T SEEM T OVERCOME. MY CODE WORKED IN SDK 8 WITHOUT DEVICE MANAGER.

THANKS

You need to remove the call to pstorage_init() in either device_manager_init() or init_p_storage() depending on which one is called first on startup.

Indeed, which is why I was trying to combine the two modules into one. I am encountering the problem when trying to combine the DM initialization functions with those required for p_storage.

Hi, pstorage_init() must only be called once before registering the first pstorage instance. Otherwise you risk getting several instances registered with the same base handle.

Edit - Added example

This example writes a dummy value to 0x3F800 in the "flash_write_timeout_handler". Should work together with the DM module.
