jtagscan

Direct the emulator to perform device discovery on the JTAG chain.

Syntax

[result =] jtagscan([chain])

Where:

result	specifies a boolean variable to which the function return value is assigned. If result is not specified, the return value is displayed on the next line of the screen.
chain	JTAG chain number {0 | 1 | -1 = all (default)}

 

Discussion

The jtagscan command causes the emulator to scan the target JTAG chain to determine the devices (e.g. processors) on the chain.  If the chain argument is omitted, all chains are scanned.  A return value of true indicates the command was successful.

The jtagchain command displays the results of the scan.  

Example

Command Input:

jtagscan( )            // scan all JTAG chains for devices

Result:

TRUE                   // scan succeeded
