Retrieve saved info on restard with pstorage module

[ppatierno]

Hello,

I need to store some app configuration on the FLASH and I'd like to use the features of pstorage module. I don't understand the following thing ...

When the application starts, it uses the pstorage_register (after the pstorage_init of course) to register itself to the pstorage module and then uses it with load and store feature. On restart I can't read what I stored on the previous execution. How for each reboot of application the pstorage knows what's my app FLASH area with my saved info ? I can't find this information ...

Thanks. Paolo.

I tried your main.c and it works. I did this simple test. I moved your code into files rgr_cfg.c and rgr_cfg.h and call rgr_cfg_init(); that execute your same code. Howerver it doesn't work. Why ? Can you execute a test with above files calling rgr_cfg_init(); from the main ?

Thanks, Paolo.

Of course I removed the code to restart the board. I reset the board manually. However my output is following :

BLE ANCS *prt = 0 rgr_cfg_save pstorage_block_identifier_get err_code = 0 block_handle.block_id = 260096 pstorage_store err_code = 0 block_handle.block_i_handle=536885612, op_code=2, result=0, p_data=536890128, da ta_len=4 p_data[0] = 16 p_data[1] = 32 p_data[2] = 48 p_data[3] = 64 d = 260096 BLE ANCS *prt = 0 rgr_cfg_save pstorage_block_identifier_get err_code = 0 block_handle.block_id = 260096 pstorage_store err_code = 0 block_handle.block_id p_handle=536885612, op_code=2, result=0, p_data=536890128, data_len=4 p_data[0] = 16 p_data[1] = 32 p_data[2] = 48 p_data[3] = 64 = 260096

It seems that *ptr is always 0 and save is always executed.

I was wrong ... executing your code (your main.c file) the *ptr is 0 on reboot so it always executes the "save" and never "load". So your main.c doesn't work for me.

im sorry, I painfully verified it again. it still works for me. Give me your whole project, so that i can debug it. Else I think we have achieved the fact that pstorage works as it should in the given SDK and SD version.

Thank you very much for helping me. I'd like to give you our project but I'd like to do that in private. How can I reach you in private for sending it ?

Paolo.
