Troubles to use FOTA + NVS Lib

[Felipe Dantas]

Hi everyone,

I working on a projetc that i have to use the NVS lib to store several user data on external flash, but i need put FOTA capability in this firmware and when i´m included the needed configs on prj.conf  and created the thread that process a connection with nRFClud, the drive of spi flash memory seems that don´t worked propertly. This issue occurs on my proprietrary board but don´t occurs on 9160DK despiste that i´ve use same parts used in DK, but with a diferent pinout in flash IC


here is my overlay:

Note the first line. This only occurs on my proprietary board. 

Some help are welcome.

Hi

You say this only occurs on a custom board. The error message here points to the SPI_NOR library not being able to communicate with the external flash memory. Can you confirm whether you have an external NOR flash on your custom board or not? The application expects that you have an mx25r6435f on the board that's connected to the device.

Best regards,

Simon

Hi Simon,

Of course! As said, i have an external flash on board, and like you can see on my code, this is an mx25r6435.

Best regards,

Felipe

Hi Felipe,

What model of external flash device do you have on your custom board? Like Simon said, the SPI_NOR library isn't able to read the JEDEC ID from the external flash correctly.

It could be a hardware issue. For that, let's go through the usual checks:

• Is the physical connection between the two devices intact?
• Are the chosen pins on the nRF9160 right for the purpose? I.e., do they have any usage restriction?
• Have this been tested with multiple boards, or just one?
• Does the board design ensure that the external flash is fully powered and ready before the nRF9160 starts communicating with it?

From the log, it seems that the error is thrown from the bootloader. Does the application have any features with the external flash? If so, do they work normally?

Best regards,

Hieu

Hi Hieu,

So, about ic model, i think that i understood somethink wrong. On my initial post, i´ve said that i´ve used the same parts used in 9160DK, that have an mx25r6435f IC flash memory and this is are declared on code, but you and Simon asked me the same think. The information that you and Simon are needing is other think? Sorry, i really didnt´t understood.

We´re in pre production stage, so i´ve some like 10 bords in lab for tests now. About the eletrical connectios, are good. As i said, the firmware work normally without the code pieces needed by FOTA scheme. I can write and read normally in the mx25r6435, booth my board and in dk.

But the most stranger thing here is that the firmware with fota work perfectly on dk, but not in mine, despiste that i´ve declared the correct pinout on overlay file like you can see in my code (and if is wrong, this firmware wouldn´t in any condition and any board).

So, trying be a little more clearer:

- IC flash memory model(i think): mx25r6435f

Work conditions:

- DK and firmware without fota: works normally. can read and write on external flash memory mx25r6435f normally.

- DK and firmware with fota: works normally. can read and write on external flash memory mx25r6435f normally and make fota update throug nrfCloud.

- Custom boar without fota: works normally. can read and write on external flash memory mx25r6435f normally.

- Custom board with fota: don´t work propertly. external flash memory mx25r6435f are not recognized by spim drive like yoou can see in firt line of application log. 

This seems to me more like a competition for pins going on behind the scenes by something in Zephyr or something called by the libraries included by FOTA.

So... is it for now.

Best regards,

Felipe

Hi Felipe,

How is the read and write on external flash done in your test no-FOTA case? In particular, I want to know if you are using Zephyr driver which initialize before main() even starts.

For the with-FOTA case, does the application work? Like I mentioned, the log suggests that the error is in the bootloader stage, but the application boot up still works. I want to know if the application can access the external flash normally.

This will help tell if the external flash isn't started early enough.

By the way, have you had a hardware design review case with us yet?

Best regards,

Hieu

[Felipe Dantas]

Hi Hieu,

To use the mx25r6435f, i followed the steps on page in the link below (Exept the initial step "Programming board controller" cause i´m in custom boar):

https://docs.nordicsemi.com/bundle/ncs-2.9.0/page/nrf/app_dev/device_guides/nrf91/nrf9160_external_flash.html

So, i include nvs.h lib and use him following his documentation in the link below:

https://docs.nordicsemi.com/bundle/ncs-latest/page/zephyr/services/storage/nvs/nvs.html

About the hardware design review case, we never had yet.

Best regards,

Felipe Dantas
