jtopal
jtopal
The jtopal command sets the environment to PALmode and begins execution of
instructions at the specified address.
Format
jtopal [start_address]
Parameters
start_address
Specifies the address at which to start executing instructions. The default is the boot
address.
Description
The jtopal command emulates the hardware mechanism for entering PALcode.
When instructions contain PALcode, you must set the environment to PALmode to
properly execute instructions. This command is required for executing downloaded
images entered in PALmode, such as a serial ROM or debug ROM image. The jtopal
command sets the environment to PALmode and then jumps to the specified location
in memory to begin executing instructions.
Example
This example starts executing instructions at address 100000
