mass production

[Marco Pennacchietti]

for the mass production what is the best solution in order to flash the nRF52?

for the mass production can I use DK PCA10040 ?

The DK PCA10040 can be used for dubbug on my the target ?

For flash and debugg on my target I need only to connect SWDCLK, SWDIO, GND ?

Thanks

Marco

The IDAP-Link CMSIS-DAP JTag supports parallel flashing of nRF5x.  Support Readback protection as well as flashing softdevice + App + DFU without the need of mergehex.

It is also prudent to pin out nReset.

Strictly speaking a reset command can be sent via SWD, however it is not uncommon for the application code to hang up SWD and thus SWD cannot be initialized. I encourage you to research this on the ARM site if you have doubts.

I've run into it numerous times with people on this website and connecting reset was always the solution.

You would be hating life if you had to reprogram 10,000 units in inventory only to find they aren't recognized by the programmer due to the firmware on them.

Hi,

For production programming we have a infocenter page here you should take a look at. We also have a more detailed whitepaper here.

Summarized:

You have two options when programming for production:

1. In-system programming (ISP): ISP is used when programming is needed after the assembly of the final PCB. Here we recommend using a SEGGER Production Programmer.

2. Socket programming: Socket programming is used when the SoC is pre-programmed before it's mounted on a PCB. Here we recommend using a production programmer from either Elnec or Hi-Lo systems.

Note that the license for the J-Link OB programmer on the nRF52 DK does not allow it to be used as a production programmer. See this post for more information.
