Protouch2 CLI User Manual
5. If the firmware location is SPI Flash ROM before SPI flash programming then
the Protouch2 tool will try to boot the device from internal ROM where it may
take time for USB enumeration (The driver loading time based on PC
performance). The default timeout value is 15 seconds. After 15 seconds time
out, if the device is not enumerated then the tool will come out of the
programming with the error code.
The default time out value can be overridden using following command,
>pt2main.exe /pspi < firmware_filename.bin> /id <index> /d
<Time_in_Milliseconds>
-
/d <Time_in_Milliseconds> is time out value
