Special Commands

Several utility commands are supported by copying text files to the mass storage disk. The filename or extension is irrelevant – the command handler reacts to content only.

Table 1. Special File Commands
Command Content	Description
`CMD:ERASE`	Executes a chip erase of the target
`CMD:SEND_UART=`	Sends a string of characters to the CDC UART. See “CDC Override Mode”.
`CMD:SEND_9600=` `CMD:SEND_115200=` `CMD:SEND_460800=`	Sends a string of characters to the CDC UART at the baud rate specified. Note that only the baud rates explicitly specified here are supported! See “CDC Override Mode” (Debugger firmware v1.21 or newer.)
`CMD:RESET`	Resets the target device by entering Programming mode and then exiting Programming mode immediately thereafter. Exact timing can vary according to the programming interface of the target device. (Debugger firmware v1.16 or newer.)
`CMD:POWERTOGGLE`	Powers down the target and restores power after a 100 ms delay. If external power is provided, this has no effect. (Debugger firmware v1.16 or newer.)
`CMD:0V`	Powers down the target device by disabling the target supply regulator. If external power is provided, this has no effect. (Debugger firmware v1.16 or newer.)
`CMD:1V8`	Sets the target voltage to 1.8V. If external power is provided, this has no effect. (Debugger firmware v1.21 or newer.)
`CMD:3V3`	Sets the target voltage to 3.3V. If external power is provided, this has no effect. (Debugger firmware v1.16 or newer.)
`CMD:5V0`	Sets the target voltage to 5.0V. If external power is provided, this has no effect. (Debugger firmware v1.16 or newer.)

Info: The commands listed here are triggered by the content being sent to the mass storage emulated disk, and no feedback is provided in the case of either success or failure.
