NRF54L15 - Unable to use Programmer(V4.6.2) of nrf connect for Desktop(V5.2.0)

[varsha@]

Hello,

I am trying to program a custom device of nrf54l15 using nrf connect for desktop app(V5.2.0) -> Programmer(V4.6.2)

I am able to program it but this is how I see the loaded file when I "READ" the file in the Device after programming.

And neither am I able to see any changes in my device.

Can You please guide me with what I am doing wrong?

I have followed the steps from General Programming Procedure Document.

Hello,

Can you please check the following for me:

Can you hover the mouse over the green area on the left. What address does it say that it occupies? Can you hover the mouse over the green area on the right and check the corresponding address there? Are they the same? And if you click "Read from the left hand menu, does the address on the right green area change?

And finally, can you please upload the hex file you are testing on, together with the hex file that is generated if you click "save as file"?

Best regards,

Edvin

Hello, 

I tried with a simple Hello World Program. This is a screen recording of the addresses. 

The addresses are matching, but the number of bytes are not .The file inside the nrf54l15 device has 42468 bytes, whereas the bytes on the file memory layout are 42450 Bytes.
Here, I am able to program, but I'm seeing the old file's traces.

Hex file Im testing on : 2502.zephyr.hex

Hex file that is generated if I click "save as file" : nRF_Connect_Programmer_1764054040094.hex

Hello,

Is it possible to upload the project that you are using? So that I can build it on my own, and test it?

Does the chip act as expected when you program it? Do you see any logging? I see that the addresses on the left and right hand side are the same, so it is just the parcing that is not correct. In fact, MBR is not even a thing when using nRF Connect SDK. It is an old term for part of the softdevice in the nRF5 SDK (which is not compatible with the nRF54L15).

If the app doesn't work as intended, have you tried programming it using nrfutil directly? "nrfutil device program --firmware <path to hex file>

Best regards,

Edvin

Hello,

I'm really sorry for the late reply. 
This is the project I'm trying to program : 
8562.hello_world.zip

I will give this a try as well. I have not tried this yet.

What happens if you flash it, and then reset the device (power cycle)? Do you see any output on the UART of the custom device? When I build this for the nRF54l15dk using NCS v3.1.1, I can see this:
