The macro "PERSISTENT_STORAGE" set to 1, but TX packet sequence number still start from 0 when Soc reset

[oplinux]

Dear friends,

I want to store the sequence nunber in flash, from the case we can know the mechanism.

I found a strange phenomenon that I flashed a serial example(nrf5_SDK_for_Mesh_v5.0.0_src\examples\serial) in my 52840 DK, in the source code the macro "PERSISTENT_STORAGE" default set to 1, as below image shows:

However, when I reset the 52840 DK, the TX packet sequence number still start from 0 and when I reopen pyACI script the log shows:

Could you tell me the reason why TX packet sequence number still start from 0 when Soc reset?

Thanks.

Best regards,

Oplinux

Hi Oplinux,

Please let me know this can help or not. Thanks.

Hi Amanda,

Thanks for your reply.

I have enabled PERSISTENT_STORAGE in the Project option -> Preporcssor Definitions as you shows above, however,  there is many warning informations when I rebuild the project:

[oplinux]

Could you test the serial example(nrf5_SDK_for_Mesh_v5.0.0_src\examples\serial)  in your DK for me, can you find the sequence number increased when the Soc reset.

Thanks.

Hi, 

The support staff is reduced during the summer holidays, and you may experience delayed answers.

I enabled PERSISTENT_STORAGE in Preporcssor Definitions of the serial example and get the different sequence numbers when the Soc reset. Before that, the sequence numbers is the same.

Thank you Amanda,

Unfortunately, I must edit the file nrf5_SDK_for_Mesh_v5.0.0_src\examples\serial\serial_nrf52840_xxAA_s140_7_2_0.emProject directly, as below

if enable PERSISTENT_STORAGE in the Project option -> Preporcssor Definitions as you shows above will cause redefined warning, as I uploaded picture, you can find this warning.

So, is there other workaroud to make "PERSISTENT_STORAGE " set to 1

Thanks.

Best regards,

Thanks for your reply, Amanda

Can I edit the macro "PERSISTENT_STORAGE" in SES directly, and why enable PERSISTENT_STORAGE in the Project option -> Preporcssor Definitions  will caused redefined warning?

[Amanda Hsieh]

It's the same. When you edit from Project option -> Preporcssor Definitions and save, it will reflect in the .emProject file.

[oplinux]

Thank you Amanda,

But when I enabled PERSISTENT_STORAGE in the Project option -> Preporcssor Definitions  will caused redefined.

I can't find the reason.

[Amanda Hsieh]

Not sure what you modify the example, so I would suggest you redownload the SDK to test.
