nRF5340 Burning Network Code With Application Code And Device Can Be Advertise Immediately?

[mw lee]

Hi Sir,

nRF Connect: v3.6.1
NCS: v1.5.0 and use original example to build code,
Net core: hci_rpmsg example
Application core: peripheral_uart example

H/W device: nRF5340 DK Board
Programmer: use nRF Connect or DOS mode.

'nRF5340 2in1 merge - Net and App.bat' for nRF Connect Programmer use,

'nRF5340_programmer.bat' for DOS mode use,

The device does not advertise immediately after burning hex files under the nRF Connect programmer
or DOS mode, and the device must be re-powered before it can be advertise.

First burning hex files:
I can't see the device advertising, device only LED1 blinking, it seems network code no work,
and device current consumption about 0.5mA.

Then after re-power device:
I can see the device start advertising, and device current consumption about 0.62mA.

I want to burn hex files and can see device to advertise immediately, how can I solved the problem?

Thanks.

Hello,

Please make sure you are using the latest version of nrfjprog ( nrfjprog --version : 10.12.1 at time of writing). I have seen this problem with --pinreset before, but only with earlier versions of nrfjprog.

Best regards,

Vidar

Hi Sir,

The nRF-Command-Line Tools is 10.12.1 now.

Hi,

Does it work now after you updated to version 10.12.1?

Thanks

Hi Sir,

Problem still exists, because previous test was already 10.12.1,

I will try to use NCS v1.5.1, thanks.

Hi Sir,

Under DOS mode I retest v1.5.0 and v1.5.1 burn then advertise is fine,
but using nRF Connect programmer for burning requires re-powered
before you can see the advertise.

Question point: use nRF Connect programmer to do 2in1 burning,
and finally whether Nordic can add a 'hardware reset' action,
which may be need to modify the nRF Connect program.

Thanks.
