CC3200: OTA & Max Size Uniflash setting

Hi CheWei,

You can refer to this page for detailed instructions and overview as it relates to OTA for the CC3200 Uniflash tool.

In the configuration and programming section it states: MaxSize 0 to indicate the original file size. Please note that for production devices, the maximum possible size is 245760 bytes (240KB). The reason is that the RAM size is 256KB and 16KB are required by the system

Hi Austin,

Thanks for your help.

I saw that Wiki and knew you said that....

But i really can't understand it. Could you give me a example?

Mcuimg1.bin is my factory default so i can set "0" in max size. It never will be updated by OTA.

Mcuimg2.bin and mcuimg3.bin are going to be updated by OTA in the future. I can set "240k" in max size and i don't care if it has a more same free space at cc3200 flash?

Or i only can set "120k" in any max size?

Hi CheWei,

The maximum possible size is 245760 bytes (240KB). This is what should be set for Mcuimg2.bin and Mcuimg3.bin.

Hi Austin,

But I don't update and verify Mcuimg2.bin and erase it at UniFlash. So max size set to 0.

Mcuimg2 and Mcuimg3 are used and updated by OTA.

Is it correct?

Thanks
