Hi,
I have external PCB, looks like this:
Need help with flashing the nRF52832 chip via nRF52 DK, please.
External PCB have identical pin assignments as QFN48 pin assignments (https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.nrf52832.ps.v1.1%2Fpin.html&cp=2_1_0_3&anchor=pin_assign)
Wired by this schema:
| External PCB | nRF52 DK | |||
| NAME | PIN | NAME | PIN | |
| VDD (3 Volts) | 48 | VDD | VDD | |
| VDD (3 Volts | 48 | VTG | VTG | |
| SWD IO | 26 | SWD IO | SWD IO | |
| SWD CLK | 25 | SWD CLK | SWD CLK | |
| GND (VSS) | 45 | GND DETECT (P20) | GND DETECT (P20) | |
| GND (VSS) | 45 | GND | GND |
I'm using SEGGER Embedded Studio but when I try Connect J-LINK I get error:
Failed to connect to target. No idcode detected. Please check connection and Target interface Type
Badly wired pins ? Or is problem in something different ?
nRF52 DK flashing (Build and Run) works perfectly fine.
