Flashlite 186 User’s Manual JK microsystems

Overview

The Flashlite 186 single board computer is based on the RDC R8822 microcomputer. The R8822

is a high performance, 16-bit, single-chip microcomputer that is software compatible with the

80C186 family of microprocessors. DOS compatibility allows development in a familiar

environment with a wide range of tools. High endurance flash memory eliminates EPROM

programming without worry of damaging the onboard non-volatile memory with repeated

program cycles. Applications are uploaded directly into the flash disk. Expansion options provide

high capacity flash storage eliminating the size and reliability problems associated with electro-

mechanical storage devices.

Software development for the Flashlite 186 is remarkably simple and quick. Programs are written

on a PC compatible computer in the language of your choice. After your application has been

compiled or assembled and linked into .EXE or .COM form, it is uploaded to the Flashlite’s flash

disk with your favorite telecommunications program using the X-Modem protocol. The

application can then be tested and debugged through the serial console. When the application is

running to your satisfaction, the startup batch file can be modified so that the application will

load and execute upon reset or powerup.

Overview

JK microsystems Flashlite 186 User’s Manual

Operation

The Flashlite is configured with two ‘disk drives’A: and B:. Drive A: contains DOS, the BIOS,

and utility programs essential to the operation of the Flashlite. Drive A: is read-only. Drive B: is

read/write and contains optional utility programs and is available for user files and applications.

The serial console port for the Flashlite has been implemented using bit I/O to keep the processor

serial ports free for user applications. The port is configured for 9600 baud, 8 data bits, 1 stop bit

and no parity. This is the primary mode of communicating with the Flashlite. DOS and the BIOS

treat this port as the logical devices STDIN and STDOUT, in place of a keyboard and monitor.

The console serial port is intended only for use as a development tool. While it is in use,

it disables interrupts for a significant period of time. This may cause disruptions with the

supplied serial port drivers and other devices and functions requiring interrupt support.

When power is applied to the Flashlite or when it is reset, the board goes through its initialization

procedure and then starts DOS. A simple (read-only) AUTOEXEC.BAT file is executed and then the

board is ready to use. The batch file performs several functions before the user is given control.

The DOS search path is set, the DOS prompt is set, the CTRL-C flag (discussed later in this

manual) is checked and finally, an attempt is made to execute a file named STARTUP on the B:

drive. This provides a convenient way for custom applications to execute immediately after

initialization of the Flashlite. If you wish to have your application start automatically, create a

batch file named STARTUP.BAT that invokes the program. Renaming your application

STARTUP.EXE or STARTUP.COM is not recommended. If this is done and the program locks up,

typing CNTL-C at bootup may not break the program and exit to the DOS prompt.

Although the flash memory devices used have a guaranteed lifetime of over 10,000 write

cycles, it is possible for an application to quickly wear them out. The flash memory is

intended to store programs, and setup data which is normally not changed. Avoid storing

data or frequently changed information on the flash disk.

Operation

Flashlite 186 User’s Manual JK microsystems

Getting Started

To begin development with the Flashlite, you will need a PC compatible computer with a

telecommunications program and a free serial port. Connect the Flashlite’s Debug/Console Port

to the PC’s serial port with a 9-pin serial cable (straight through wiring). Run the

telecommunications program and configure the serial port for 9600 baud, 8 data bits, 1 stop bit

and no parity. Apply power to the Flashlite, using our A/C adapter PN 88-0006 or a source of

unregulated DC between 7 and 34 Volts, capable of supplying 2 Watts. Observe the polarity

indicated on the board silkscreen.

The Flashlite should respond with a welcome message and a B: prompt. Enter DIR to look at the

directory of drive B:. If you do not get a welcome message or echo of the characters that you

type, you need to check your serial port setup. To test everything but the Flashlite, remove the

serial cable from J6 and jumper pins 3 and 5. If characters typed on the keyboard are not echoed

on the screen, the problem is with your setup. You must resolve the problem before you can

continue.

If you were able to do a DIR, take a few minutes to explore the contents of the Flashlite’s file

system. You will find all of the essential utilities on drive A: and some optional programs on

drive B:. Drive A: is write-protected and cannot be altered. Drive B: is read/write and can be

changed or reformatted.

After you have looked at the programs on the Flashlite, the next step is to try to upload a file.

This is the procedure for getting a file from your PC to the Flashlite. On the Flashlite, type the

command UP followed by the name of the file you wish to upload. The Flashlite will begin

sending characters to your PC polling it for the file.

On your PC, start the transfer, usually by pressing the PgUp key. The telecomm program should

respond by requesting the file name and protocol. Enter the file name and select X-Modem for

the protocol. The transfer should start and when it is complete, you should get a new B: prompt

on the screen. If the transfer does not work, the problem is most likely the Carrier Detect signal

(pin 1 on the DB-9 connector) into the PC being sensed as low or false. Make sure that the signal

is at least +3 volts into your PC if you are not able to transfer files.

Getting Started

JK microsystems Flashlite 186 User’s Manual

If the transfer terminated without problems, you have a working development environment for

the Flashlite controller. To transfer files from the Flashlite to the development PC, use the DOWN

command described in the Utilities section of this manual.

The Flashlite does not have a hardware clock calendar. The time and date will be maintained by

DOS until the power is cycled. If the correct time and date are required after a power cycle, they

must be set either from the command prompt or via user software. The time and date can be set

with the following commands:

B:\>TIME 13:30:00 Sets the time to 1:30 pm

B:\>DATE 10-29-2002 Sets the date to October 29, 2002

When power is applied to the Flashlite, one of the first things the BIOS initialization code does is

check for a CNTL-C character typed at the console. If this character is typed as soon as the board

is powered up or reset, a flag is set which overrides some of the initialization process. When

DOS runs its AUTOEXEC.BAT file on drive A:, the state of the CNTL-C flag is also checked and

any user application set to run on drive B: is not loaded. This insures that a hung application or

quiet console can always be interrupted.

If the CNTL-C flag is not set, the AUTOEXEC file will attempt to transfer control to a file named

STARTUP on drive B:. DOS also looks for and, if present, loads CONFIG.SYS from drive B:.
