I am trying to use the nRF54L15 DK board to flash a Fanstel BM15M module.
Fanstel BM15M module link:
Fanstel BM15M Module
I am using the nRF54L15 DK board with the external Fanstel BM15M module through the P19 debug connector.
Connections are as follows:
Using nRF54L15 DK (P19 Debug Out):
-
SWD0_VTG → BM15M VCC
-
SWD0_SWDIO → BM15M SWDIO
-
SWD0_SELECT → GND
-
SWD0_SWDCLK → BM15M SWDCLK
-
GND → BM15M GND
However, the external target device is not detected.
Earlier, I used the nRF52840 DK to flash third-party nRF52833 modules without any issues, so I also tried using the nRF52840 DK with the BM15M module.
Connections using nRF52840 DK:
-
SWDIO → BM15M SWDIO
-
SWDCLK → BM15M SWDCLK
-
VCC → BM15M VCC
-
GND Detect → GND
-
GND → BM15M GND
But in both cases, the programmer is unable to detect the external BM15M device.
I am not sure what mistake I am making.
Questions:
-
Does the BM15M require the RESET pin to be connected?
-
Is there any special configuration needed for the nRF54L15 DK P19 debug interface?
-
Could the BM15M have debug protection enabled by default?
-
Is there any additional requirement for external SWD programming with this module?
Any suggestions would be appreciated.
Thanks and regards,
