Programming multiple modems at once?


#1

Greetings All,
As our development becomes closer to production, We are looking for ideas to be able to program our WP8548s in the most time-efficient way possible. Ideally, up to 10 at a time would be nice.

So far, we’ve found that using the windows executable build hangs if there is more than one modem connected via USB. We’ve also considered changing individual IP addresses of each of the 10 modems and using multiple SSH sessions to copy the files over and run updates. This is a little clunky, but do-able.

Are there other/better options we should be considering? Any suggestions would be very appreciated!
Thanks,
Terry

We are using a automation script to run swicwe and swiflash in a linux pc which have better performance compare to windows fdt app but again productivity is the issue as only 1 board we can flash at a time (1 board 7 minutes). Yes we are also searching for a solution to flash multiple device at a time using 1 PC. If someone have any solution please share in this forum.

Thanks

Hi @niladridm

A new swiflash version should be available soon, offering the capability to program several units at the same time. Will keep you updated.

Any news on this?

And we change some settings via AT commands (like AT!MAPUART with requires a reboot), I guess this is stored in the modem. How can we best change this in production?

Programmatically?
Can it be stored in a cwe file?
Stored in a modem config file?
Using uartMode?
Other?

Hi @nilsarve

The new swiflash version including this feature was a bit delayed, but still planned.
Will keep you posted ASAP.

Can your chip supplier program them before delivery?

Hi @pankaj

We’ve been busy at something else for a while, but I expect to be able to get back on this soon.
Starting to have a working prototype, just need to polish it before external release :wink:
