Hi Zero,

We will update our Known Issue database with it, but for now, my colleague Sigurd described the issue here: RE: spi_flash is not running on nRF5340DK out of box .

In NCS v2.5.2 and v2.6.0, a driver update was made that expects the flash device to be in Quad I/O mode.

However, in a factory/brand new state, the flash device is not in Quad I/O mode.

nrfjprog --qspieraseall fixes it, because the command doesn't just erase the flash device, but also set the device into Quad I/O mode in its non-volatile configurations.

Hi Hieu,

I tested it and added: &mx25r64 {
writeoc = "pp";
readoc = "fastread";
};
52840-DK cannot run the matter example downloaded from ncs2.6.0. You can reproduce the problem and then use nrfjprog --qspieraseall.
But when the 52840-DK is reset after powering off and on, it cannot run. What difference does erasing bring to the flash itself? Or does Brand new DK mean there is something different about mx25r64 that causes this problem?

Hi Zero,

A fix was made in the Zephyr upstream: https://github.com/zephyrproject-rtos/zephyr/pull/71373.

and cherry picked into NCS: https://github.com/nrfconnect/sdk-nrf/pull/14812.

It should be fixed in the next release. I cannot comment on when that is, however.

You could try to cherry pick the fix as well.
The issue can be reproduced on a factory condition DK, not necessarily the 3.0.1 or newer, if you want to verify the fix.
I have not verified this, but to "unfix" a DK to be susceptible to the issue again, you can use this overlay:

&mx25r64 {
	writeoc = "pp";
	readoc = "fastread";
};

Hi Hieu,

This solution is currently acceptable. But please really fix this problem as soon as possible.

Hi Zero,

We have recorded this issue. For the time being, is this "fix" satisfactory for you? We will continue to investigate and work on a better fix, but your insight could help us with prioritization.

If you see a large impact, could you please also start conversation with your Nordic Sales contact?

After nrfjprog --qspieraseall is repaired, the matter example can always be run.

I tried running the ncs2.5.2 matter example using the unfixed v3.0.1/v3.0.2 DK and then ran the ncs2.6.0 matter example. The problem still exists.

Hi Zero,

I also found some relevant internal records yesterday and found that nrfjprog --qspieraseall fixes the issue to me.

I planned to talk with those records' authors to fully understand the technicalities before answering you, but it seems you also reached the same findings.

I would like to confirm your observation. After the Matter sample work once, does it ever fail again?

Also, if you still have a v3.0.1/v3.0.2 DK that you haven't "fixed," can you confirm if flashing a sample on NCS v2.4.x or v2.5.0 also "fixes" it?

On my end I currently cannot find a DK that I can reproduce the issue again after fixing it once.

Hi Hieu,

Maybe my test is helpful for you, I see through debug that in dev board v3.0.0 qspi initialization returns 0 and can read jedec-id = [C2 28 17]; But it is in development board v3.0.1/v3.0.2 that QSPI initialization returns 19 and reads jedec-id = [00 00 00]; You can analyze it in this direction, and I don't know how to analyze it.

I also did the following tests:
1. Connect the v3.0.1/v3.0.2 52840-DK to the pc
2. cmd enter nrfjprog --qspieraseall;
3. Download the ncs2.6.0 matter example.
Result: v3.0.1/v3.0.2 52840-DK works fine with the matter example.
Note that all ncs2.6.0 matter examples cannot be run on 52840-DK. The version of dk that I test can run may be because I have operated on external flash before.

Hi Zero,

I have been consulting internally and work off of the pointers I received but haven't gotten anything meaningful to talk about yet. This isn't straightforward, as I have feared...

I'm very sorry for the lack of good news.

I will keep trying and keep you updated.

Hi Zero,

I reproduced the issue on a nRF52840 DK v3.0.2. I will investigate this and come back to you. This seems complicated, and we are short-handed at the moment, so I unfortunately cannot promise that I will be back soon though. Sorry for this.

Hi Hieu，

I burned the hex you compiled onto the PCA10056 v3.0.1 board, but the phenomenon is the same and it cannot run.

At the same time, I asked my colleague to borrow a v3.0.0 52840-DK, which can indeed run the matter examples of ncs2.6.0. I also verified that the v3.0.2 DK cannot run the matter examples of ncs2.6.0.

Hi Zero,

I don't have a nRF52840 DK v3.0.1 with me at the moment and could not reproduce your observation with my v3.0.0.

I will try to get a v3.0.1 and test tomorrow.

To rule out any possible differences, could you please try with this hex file?
devzone.nordicsemi.com/.../matter_5F00_light_5F00_switch_5F00_260_5F00_nrf52840dk_5F00_nrf52840.hex
It is my compilation of the Matter Light Switch sample on NCS v2.6.0.
