Error: You must pass an integer between 0 and 255 as an argument to --instance
--write-pid <filename> Write the process ID to the file specified
--signal-pid <filename> Send a SIGUSR1 to the other process when ready
-c/--cable <cable name> Specifies which JTAG cable to use (not needed if
you only have one cable)
-d/--device <device index> Specifies in which device you want to look for the
Nios II OCI core (1 = device nearest TDI etc.)
-i/--instance <instance> Specifies the INSTANCE value of the JTAG debug core
(not needed if there is exactly one on the chain)
-r/--reset-target Always reset the target processor before use
-s/--sidp <address> Base-address of System ID peripheral on target
-I/--id <system-id-value> Unique ID code for target system
-t/--timestamp <time-stamp> Timestamp for target-system (when last generated)
--accept-bad-sysid Continue even if the system ID comparison fails
<filename.srec>* S-Record file(s) to download to the target
--no-verify Don't verify after downloading
-w/--wait <seconds> Wait for time specified before starting processor
(signal USR1 will terminate the wait early)
-g/--go Run processor from entry point after downloading
--stop Stop processor (leave it in a paused state).
--tcpport <port> | auto Listen on specified TCP port for a connection from
GDB (with "auto" a free port will be used).
--tcpdebug Display the GDB remote protocol running over TCP
--tcptimeout <seconds> Timeout if GDB has not connected in time specified
--tcppersist Don't stop when GDB disconnects
--thread-vars <vars> Decode target thread list using specified string
--write-gmon <gmonfile> Wait for target to complete and write GMON data
(if available) to the file specified
--wait-target-exit Wait for target to complete and return target exit
code as our return code if no other errors
The processor state after execution is chosen as follows:
1) If the GDB remote protocol is enabled then this chooses the state.
2) If the --go option is specified then the processor will be started.
3) If the --stop option is specified then the processor will be left paused.
4) If a file is downloaded or the procesor is reset then it will be paused.
5) Otherwise, the processor state will be restored.作者: luqingyun 时间: 2011-3-22 22:12
