pdn: Failed to configure CID 0, err, -1 after upgrading the SPI flash memory

[Praveen Deshmane]

Hi,

I would like to carry the full modem update.

Based on nordic website I need at least 4MBytes of flash for doing a full modem update on the nRF9160:

https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/nrf9160/http_update/full_modem_update/README.html

Currently i am using the Winbond W25Q64JV 8MBytes flash memory.

device_get_binding for w25q64jv flash memory

flash_dev = DEVICE_DT_GET(DT_NODELABEL(w25q64jv));

the above device binding information got from this ticket link

SPI flash driver w25q64jv was found successfully.

I am getting below error

RTT Error log

rtt:~$ Found SPI flash driver w25q64jv 
[00:02:30.951,354] <err> pdn: Failed to configure CID 0, err, -1
[00:02:30.951,385] <err> pdn: Failed to configure default CID, err -1

NOTE:

PDN error won't occur in other device with w25q32jv 4Mbytes flash memory.

It is occurring only in device with w25q64jv 8Mbytes flash memory.

am i missing anything in spi3 configuration of device tree? 

Please guide to overcome this problem.

Hi,

 

The error returned (-1) from pdn_init() indicates that the modem lib is not yet initialized.

I would recommend that you initalize the pdn connection in your application by setting :

CONFIG_PDN_SYS_INIT=n

And initialize PDN prior to executing AT+CFUN=1 (ie. before lte_lc_init()), similar to what is done in the lwm2m sample:

https://github.com/nrfconnect/sdk-nrf/blob/v2.0.0/samples/nrf9160/lwm2m_client/src/main.c#L407-L413

 

Could you try this and see if this works better?

 

Kind regards,

Håkon

Please tell me what is wrong.

Hi,

 

The pdn_ctx_destroy is potentially called before pdn_init. is this intentional?

Could you share a larger log to see where you get this warning returned?

Does everything else work as intended?

 

Kind regards,

Håkon

[Praveen Deshmane]

The pdn_ctx_destroy is potentially called before pdn_init. is this intentional?

It has written by some other developer. I commented that code, i still getting the problem

<err> LTE: write certificates error

we have increased flash memory to 8Mbytes does it affecting?

Hi,

 

I am not sure how changing only the spi memory overlay shall give you this sort of behavior.

Are you certain that you have updated the modem firmware on the new device?

 

All the return codes indicate that the modem fw isn't fully initialized, while the SPI flash seems to be detected as expected.

 

Kind regards,

Håkon

[Praveen Deshmane]

Hello Hakon,

I figured out myself and solved this problem yesterday itself. It was modem firmware update problem.

Thank you for reply too. I really appreciate it.

Hi Praveen,

 

I am glad to hear that you found the root cause.

Hope you have a wonderful day!
