nRF54L15 Custom board Firmware issue.

[PoojaK]

I have designed a custom PCB using nRF54L15 SoC and have gotten it verified from Nordic people. I will share the gerber here as well. I am using VS Code for flashing the code into this custom PCB using nRF54L15 DevKit. I have ensured and checked that the code is definitely not being flashed into the DevKit but in my Custom PCB only. My problem is that the RF section is absolutely not working. Although the same code works for nRF54L15 DevKit. In a previous ticket it was said to me that it might be software issue because the hardware seems absolutely fine. I will also attach m VS Code config snippets. I am stuck in this loop and would really appreciate if my issue gets resolved. I have also attached the code. Thank you.5086.GERBER-SPJ_NORDIC_NRF-V1.zipperipheral_uart_5.rar.

Hello,

My problem is that the RF section is absolutely not workin

So I will assume that means all code run as expected with no errors when you advertise. If that is correct, then the next step is to run the radio test and setup a tx carrier, and measure on a spectrum analyzer the frequency accuracy of the carrier. For instance if you setup a carrier on channel 2, then the carrier should be on 2402MHz, with a max deviation of 96kHz (preferably less).

I do not have a spectrum analyzer. But I think the issue is in the VS Code config file or settings that i have made for custom PCB. What are the exact changes that I need to make in the config file to make it suitable to run with nRF54L15 SoC ? What should be my target board selection?

Can you share the schematic? You can make a new private case if you don't want to share it on a public case.
