CC3100MOD programming

Other Parts Discussed in Thread: UNIFLASH, CC3100MOD, CC3100

I'm a little confused about programming the CC3100MOD in production. We intend to use the SPI port as reccomended, and we don't want to use a special hardware tool in production (to support Uniflash). The main processor in our application (which is running linux) has a spare UART and one spare 3.3V GPIO. We intend to power the CC3100MOD from our systems main 3.3V power source.

To program the CC3100MOD, some sources on the wiki and in other TI documentation suggest that you need the UART and to control nReset. Others suggest you need access to nHib, and still others suggest access to SOP2 is required.

Can someone direct me to a definitive programming specification that outlines not only the hardware requirements, but also the protocol/command set for using a UART to reprogram the CC3100MOD?

Thanks,

Hi,

Supporting collateral will be available in Dec.

For CC3100, UART is mandatory only when programming device connected to blank serial flash. Since you are using a module, the serial flash is not blank and you can use SPI interface. You can program from host over SPI interface using SimpleLink file system APIs such as sl_FsOpen, sl_FsWrite and sl_FsClose.

The FW file format that can be used for programming via host interface will be available in the comming weeks.

Hi Ben,

Thanks for the clarity on that point. Still tho, any chance you could tell me what signals would be necessary to program the unit should it become bricked somehow? My board is going out in 36 hours.

Hi Ben,

Where can the FW file format be found once you release it?

We will release a new SP soon. There will be no change to FW only the addition of another format.

What happened to your unit?

I am looking for the firmware upgrade protocol via SPI as well. I need to see document describes how and where the firmware stored in CC3100. A sample of uniflash code with the upgrade firmware protocol is handy. I can't wait to see the supporting collateral.

Thanks
