Minimon is provided in the SCAMP\Minimon folder. Select setup.exe and follow the on-screen directions.
INITIALIZATION OF MINIMON
Run Minimon program. Select Target\Configuration. Fill in boxes as shown below.
(If SCAMP does not appear in the Controller type list,
Select Interface\Terminal Settings. Fill in as shown below.
This completes initialization of the Minimon program.
DOWNLOADING NEW OPERATING SYSTEM TO SCAMPS FLASH
Downloading of SCAMPs operating system to flash occurs in five steps. The first step is to connect SCAMP to the host computer and initialize SCAMP for downloading. In the second step the operating system is downloaded into SCAMPs RAM memory. In the third step a short additional program is downloaded. In the fourth step this short program is run. This program copies the operating system from SCAMPs RAM into SCAMPs flash memory. The fifth step is to restore SCAMP to its normal operation status.
STEP 1 Connect SCAMP and initialize it for downloading.
Insure that SCAMP's batteries are sufficiently charged to operate SCAMP for 30 minutes or more. Open SCAMP. Remove the longer electronics cover. Connect the RS232 cable supplied with SCAMP to the connector as shown in the following picture:
Jump SCAMPs bootstrap jumper. This is just visible in the picture. It is directly above the 4 circuit USB connector with black, red, white, green wires. There should be a jumper slid over one post of the connector. Use this jumper to jump both posts.Run the Minimon program. After the program appears, press SCAMP's reset button (the white circle visible at lower left in the picture above). SCAMP will print a banner display that gives information about the SCAMP hardware and the software revision date.
Select File\Load and browse to the directory containing the operating system to be loaded. An example:
Select PF_DEPLOY xxx.H86 (where xxx indicates the revision number, example '103').
Minimon loads this program into the host (not the SCAMP!) computer after you select
Select Target\Download Selection. Minimon downloads PF_DEPLOY.H86 to
SCAMPs RAM memory. It is not placed into SCAMP's FLASH memory at this time,
only downloaded to RAM. The next steps move it from RAM to FLASH
STEP 3 Download the flashing program
Repeat step 2 except load PFlash.H86
STEP 4 Run Pflash.H86 to program SCAMPs flash
Select Target\Disassemble Debug. The following screen will appear. Select GO The Pflash.H86 program (now within SCAMP) copies the operating system from SCAMP's RAM memory to SCAMP's flash memory and will print its status as it programs the flash. Select Cancel to exit the screen. (Selecting Cancel will not influence SCAMP it is performing the programming using its own internal CPU.) When copying is completed SCAMP forgets about Pflash.H86.
STEP 5 Restore SCAMP to normal operation
Remove the jumper that you installed in Step 1. Place it back over one post only. Press the reset button. SCAMP should print its banner, now showing a new software revision in the banner.
This completes installing a new operating system into SCAMPs flash memory.
