PCA10056 v3.0.1 cannot run the matter example of NCS2.6.0

[zero]

Dear support team,
I now have three PCA10056 v3.0.1 versions of nRF52840-DK. After connecting the development board to the PC, I downloaded the \v2.6.0\nrf\samples\matter\light_switch example. I opened the serial port to view the log. There is no log information, and LED1 does not flash. , indicating that the matter example is not running; download the \v2.5.2\nrf\samples\matter\light_switch example, open the serial port to view the log, there is matter log output, and LED1 will flash, indicating that the matter example has been run; 3 PCA10056 v3.0.1 phenomena consistent. Please tell me why the matter example of ncs2.6.0 cannot be run on the PCA10056 v3.0.1 development board? Please help analyze the cause and give a solution.
I found an nRF52840-DK with PCA10056 v0.9.2, which can run the matter example of ncs2.6.0.

BR,

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?
matter_light_switch_260_nrf52840dk_nrf52840.hex
It is my compilation of the Matter Light Switch sample on NCS v2.6.0.

BR,

Hieu

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 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.

BR,

Hi Hieu

Is there any latest conclusion on this issue?

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 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.
