CC3220MODA: Improve programming time through UART

Thibault Helle

Part Number: CC3220MODA

Hi!

We are now using this guide to program the CC3220MODASF in production line using the ImageCreator tool through a UART interface with XDS110. Our problem now is that the programming time is 3,5 minutes(!) which is not ok for mass scale and we must take it down to seconds.

What can we do to lower this time?

Thanks in advance

    Hi,

    For mass production is recommended gang programming via SPI - see production line guide (chapter 4). This approach may to improve your production time.

    But be aware that during programming you need to erase SPI flash (MX25R3235F) inside module. Chip erase of this flash is typ. 26s (max. 76s). With fast production SPI programmer (e.g. Elnec BeProg2) you can achieve approximately 50sec programming of full SPI flash (25sec erase + 25 sec programming+verification).

    update: btw ... if you don't have option for direct SPI flash programming and you need to use UART, there is not much options how decrease your programming time. Only way is to use small application image and full application program via OTA. This approach will add complexity into your production but slightly improve your production programming time.
