Components test

Components test will automatically and consecutively test DataFlash device, each of the parallel ROM or Flash

devices and Firmware integrity. Even if Firmware is part of the first ROM or flash device, it should be checked

separately

To start component test press and hold MINUS switch then also press PLUS switch.

Firmware enters in component test and display shows:

- "dFl" while DataFlash is under test

- "rOM" while ROM or Flash devices are under test

- "Fir" while Firmware integrity is under test

When test is ended, state of the 5 first Intrument LEDs shows the test result. If the 5 LEDs are on then all

components test were successfully passed.

- If Inst 1 LED is off then DataFlash test was fail

- If Inst 2 LED is off then ROM or Flash device test was fail

- If Inst 6 LED is off then Firmware test was failed

Warning: ROM and Firmware test can be passed with success only if binary files for ROM or FLASH devices have

been created with Dream "MakeROM.exe" tool.
