Power up diagnostics

Europa’s onboard diagnostics are quite extensive – much more so than the original Roland code. An NVRAM corruption on the Jupiter 6 can render the board useless with the Roland code! Europa is not susceptible to crashing with a corrupt NVRAM and will repair it if corruption is found. Also, patches and presets are stored in the Europa chip’s flash so it is not susceptible to losing patches if the controller board’s battery fails.

When problems arise, Europa will display boot codes. Boot codes are identified by the board’s LEDs being in the following state just after board powerup:

•All LEDs are off except…

•LFO 1 LED Is blinking, steadily lit or off

•LFO 2’s Rate LED is blinking or other bender board LEDs are lit

•Only LEDs on the BANK and NUMBER buttons are lit solid or blinking (indicating a boot code)

As an example, if the text indicates that a code of A-2is shown, only BANK A and NUMBER 2 are shown along with the LFO 1 and LFO 2 LEDs as described above. Like this:

Figure 3 – Boot code A-2 shown on bootup

Some boot codes are fatal and the board will not boot, and others are purely informational. All boot codes are indicative of a problem. With recoverable boot codes, pressing a key or a button on the front panel will cause the Jupiter 6 to continue booting. Fatal boot codes will cause the board to hang, since they indicate a problem that prevents Europa’s operation.

Diagnostic information is not particularly useful to an end user of Europa, but is extremely valuable to the technician who is diagnosing or repairing a malfunctioning Europa enhanced Jupiter 6. While the A-Fand 1-8lights are being strobed left and right, Europa is running the diagnostics as described in Figure 4. This chapter gives a sequential list of power up diagnostics that Europa performs as it boots.

Group A boot codes

The A group of boot codes indicates unrecoverable component diagnostic failures in either the Europa chip itself or the scratch RAM chip on the controller board. They are not recoverable, and Europa will not run:

A-1Internal CPU RAM failure. This is a failure of the Europa chip itself. If the Europa is still under warranty, contact Synthcom Systems, Inc. to arrange a replacement.

A-2Scratch RAM failure. This failure occurs when Europa cannot get reliable data storage on the scratch RAM chip on the Jupiter 6’s controller board. Either the scratch RAM chip itself is bad or the interconnecting circuitry is making communication with it unreliable. This is not a failure with the Europa chip! If this occurs directly after a Europa installation, look for solder bridges or unintentionally cut traces.
