# TI CC3200 mode selection jumper

**Programming mode**

Under the programming mode, you need to VI and VO short on power, CC3200 will receive as a writer, it will be the serial data received by the SPI mode file system writes to the external SFLASH, but the programming is completed after not running, you need to disconnect VI and VO, then on again, then it will be read in the file system SFLASH into memory and execute code. As shown in Figure.

**Run mode**

Run mode, you need to disconnect VI and VO, then power on, CC3200 will SFLASH read from the file system into memory and run. In this mode, plug in the JTAG interface, using the IDE's DEBUG function, and the code will be downloaded from the JTAG interface to the memory to run, you can perform single-step debugging. For fast functional verification, this is the fastest way. However, after a reset circuit, CC3200 will be new to SFLASH read the file system operation. As shown in Figure.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://bananapi.gitbook.io/bpi-g1/zh/ticc3200modeselectionjumper.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
