I'm experiencing an issue while trying to flash my custom board based on the nRF5340 using the nRF54L15-DK as a programmer, with SDK version 3.0.2.
The nRF5340 is recognized correctly in the nRF Connect for VSCode plugin, and the NET core appears to be programmed successfully.
However, when flashing the APP core, I receive the following error:

Sometimes, I’m able to program the custom board without issues using the same setup. But currently, I’m no longer able to flash the APP core at all.
When using a J-Link programmer, I'm able to flash the custom board without any issues.
Has anyone faced a similar issue or can suggest how to fix this?
Thanks in advance,
