Daplink software released by arm-mbed for nrf52840 dk does not detect external target

[madblue]

Hi,

I need to upload compiled binaries from mbed studio to my custom board based on nrf52840 using nrf52840 dk.

I have replaced the jlink software(J-Link OB-SAM3U128-V2-NordicSemi 170724.bin) on nrf52 dk with daplink software for nrf52840 dk released by arm-mbed.

By making this change, I was able to upload from mbed studio compiled binaries to the nrf52840 dk and it worked well.

Now the problem is that, i am not able to upload the mbed compiled binaries to my custom board. I have tried to connect it with nrf52840 dk as we use it with jlink(By connecting the swd lines of dk to my custom board) but it didn't work. it is getting uploaded to dk.

The daplink  software for nrf52840dk released by arm-mbed is shown below, (i have used this one)

armmbed.github.io/.../0253_sam3u2c_mkit_dk_dongle_nrf5x_0x5000.bin

i want to know what is the best way to use mbed studio with nrf52840 boards ?

(fyi, i am able to upload to my custom board using nrfjprog and everything is fine. )

You can always cut SB47 again if you need to use the onboard nRF52840. I will make note of this and report it internally, but I can't guarantee that Daplink/mBed compatibility will come out any time soon.

Best regards,
