凯尔不检测DA14580 J-Link debug mode

Hello,
We are having our customized board using DA14580-01, we are using an external 16MHz oscillator to feed to the chip and the voltage levels as per DA14580 datasheet(1.2V peak-to-peak).
We are able to even observe 32.768Khz across XTAL32Km and XTAL32Kp.
But when we try to connect to J-Link using Keil project and enter debug mode, we are unable to see the BLE chip being detected
i.e. In Debug mode==>Settings==>Sw Device, we are unable to see any IDCODE.

Thanks

Hello Joaquin,

Hello Joaquin,

The reset pin is connected to "RST" pin of DA14508-01 chip.
Is there any specific reset sequence to be followed?
I am unable to locate any reset sequence fro DA14580 in datasheet "DA14580_DS_v3.0.pdf".

Thanks
asmaitha

Hello Joaquin,

Hello Joaquin,
We have even connected the "RST" pin of DA14580 to Gnd ,
Even then we are unable to detect the BLE chip in Debug mode(J-Link LITE + Keil project).

Thanks
