Your OpenOCD command should look like this:
|
|
openocd -f interface/<jtag adapter>.cfg -f tools/firmware-recovery.tcl -c \"<commands>*; shutdown\"
|
|
|
|
Where:
|
|
<jtag adapter> is one of the supported devices, e.g. ftdi/jtagkey2
|
|
<commands> are firmware-recovery commands separated by semicolon
|
|
|
|
Supported commands:
|
|
firmware_help get this help
|
|
list_boards list known boards and exit
|
|
board <name> select board you work with
|
|
list_partitions list partitions of the currently selected board
|
|
dump_part <name> <filename> save partition's contents to a file
|
|
erase_part <name> erase the given partition
|
|
flash_part <name> <filename> erase, flash and verify the given partition
|
|
ram_boot <filename> load binary file to RAM and run it
|
|
adapter_khz <freq> set JTAG clock frequency in kHz
|
|
|
|
For example, to clear nvram and reflash CFE on an RT-N16 using TUMPA, run:
|
|
openocd -f interface/ftdi/tumpa.cfg -f tools/firmware-recovery.tcl \\
|
|
-c \"board asus-rt-n16; erase_part nvram; flash_part CFE cfe-n16.bin; shutdown\"
|
