hangs at nrf_fstorage_erase(). (debug shows -> Unknown function at 0x00000978)

[prithvi25]

So I am trying to store a few configuration parameters in flash.

I am using nrf_fstorage for that.

so before storing the parameters, I am erasing the flash but, it hangs at "return (p_fs->p_api)->erase(p_fs, page_addr, len, p_context);" in nrf_fstorage_erase().

How to solve this problem?
Thank you.

Hi, 

Do you use nrf_delay in the project? If so, is it possible to replace with non-blocking delay?

Please see a similar case that might help you.

I checked it. I have not used any delay API in my project.

Hi,

Could you try to use the HardFault handling library to determine the cause of the Hardfault? As my colleague explained in this thread.

I went through that thread.
so after "return (p_fs->p_api)->erase(p_fs, page_addr, len, p_context);" in nrf_fstorage_erase() it shows BusFault.

So what should I do next?

And if I continue execution and then pause it (in Debug mode), it goes to HardFault_Handler
