Bossa Program Port and no J-Link on dev board

Hello,

during works with DA1469X development board pro something happened and motherboard is no longer detectable as J-Link probe.

In the system (Win10) I can see Bossa Program Port under COM ports (+ 2 additional COM ports).

Also green LED near SAM chip does not lit or blink.

On the second board (attached to the same USB port) everything works as expected and J-Link is enumerating on USB and it is possible to proogram/debug DA14699 daughter board.

 

Is there an J-Link image available that can be written to SAM chip using BOSSA programmer?

Or maybe SAM switched somehow to bootloader mode and can return to operation as J-Link probe?

 

Thank you for support.

Hi ky3orr,

Hi ky3orr,

No, there isn’t anything shareable regarding the SAM chip. Can you please connect both pins of J6 and check if anything changed? From my understanding, the Pro-DK was fully functional, but somehow you are not able to detect it? Did I understand correctly? Did you do any modifications in the firmware? Or di you change the jumper configurations?

Thanks, PM_Dialog

Hello again,

Hello again,

 

To be speciffic I use DA14695 PRO development board with attached DA14699 daughter board.

I have not done any thanges to SAM micro firmware.

Shortening J6 does completely nothing - what is it used for?

 

As previously mentioned board enumerates itself on USB as BOSSA Program Port + 2 additional COM ports.

Look like SAM is running a kind of Mirochip bootloader. Maybe J-Link firmware was corrupted on one of power cycle and now bootloader executes?

 

Or maybe I should clone Jlink OB binary from other DA14695 PRO board and flash using BOSSA Flash Programmer from SAM devices?

 

Thank you for support - currently the board is not usable.

Grzegorz
