Leapster Explorer: USB Boot
This how-to will explain a bit about the USB booting process of the Leapfrog Explorer and provide a Linux shell script to download the file to the device.
Terminal app to check progress
File:Pager.v0.1.tgz shell script
DJHI or other means of gaining a UART Console (optional)
To turn on USB Boot mode, with the USB connected hold down the Right and Left Shoulder buttons along with the ? mark button, while holding them down, turn the power on, you should end up seeing a screen showing the LX connected to a PC.
Download the Pager script and save it in a directory, make sure it is set to execute file permissions for your user. From a terminal run
$ sudo ./pager.sh <filename>
Where file name is the name of the firmware you want to download to the Explorer. In your terminal window you ran the script in, you should see something like this.
1: Writing bytes:0 -> 16383 to /dev/sdc SCSI Status: Good 2: Writing bytes:16384 -> 32767 to /dev/sdc SCSI Status: Good ... ... 430: Writing bytes:7045120 -> 7061503 to /dev/sdc SCSI Status: Good 431: Writing bytes:7061504 -> 7077887 to /dev/sdc Verifying /dev/sdc
and it will be done. You can check in your UART terminal, and you should see it uncompressing Linux.
