What To Do If - Fujitsu DevKit16 User Manual

What to do if ...

This chapter includes hints for DevKit16 operation, which
should be checked before call technical support
• The green LED on the Mainboard is blinking. What should I do ?
1. The MD0-MD2 CPU pins are pulled to '0' by some device.
Check the MD0-MD2 DIP switches on the CPU board - they
must be all "OFF".
• The Mainboard does not work. What to do ?
1. Check if the green diode shines without blinking. If it does,
switch the MD0 switch on the CPU "ON" and press reset. If
the diode blinks, FPGA is working and you can proceed with
the next steps. If it doesn't, there is something wrong - check
your power supply voltage, jumpers J4, J11, J12, J29 (all
must be "OFF") and the FPGA EEPROM. Try to burn the
default FPGA content to the EEPROM. If this doesn't help,
you must contact our support.
2. Switch MD0 to OFF and set the Serial programming mode
on the Mainboard DIP switches. Set all the jumpers to their
default positions (see the CPU and Mainboard layout
figures), and the J1 jumper to the 2-3 position. Connect the
serial cable to the USER UART port
3. Run the FlashTool. Set the "External bus free" to "yes" and
press "Connect". If you pass this step successfully, it means
that CPU is working properly. If not, there is something
wrong with the PC to CPU communication. Once more,
check all of the mainboard jumpers and also your PC
communication interface, if you can.
• The Processor Expert™ debugger doesn't start (kernel does not
response)
1. Check the communication cable. It has to be connected
properly on both sides. Also, close all programs that could
possibly use the communication port you are trying to use.
2. Check the serial line reset LED diodes (D11 and D10). If
they shine, the mainboard is reset by serial line. In that case,
