Chapter 13—CPU Board
13.5 Startup
The prerequisite for the printer to start is that a fl ash memory SIMM with
a boot sector is fi tted in J20. A SDRAM SIMM must also be installed in
J10.
At power up, the printer starts executing code in the boot sector and one of
the following sequences will be performed:
1. A Compact Flash card with a fi rmware is recognized.
- The fi rmware will be copied from the memory card to the internal
SDRAM.
- The processor will start to execute code from SDRAM.
- The fi rmware on the memory card will be copied to the internal fl ash
memory.
2. A valid fi rmware is recognized in the internal fl ash memory.
- The fi rmware will be copied to SDRAM and the processor will start
execute code from SDRAM.
If the printer is fi tted with an EasyLAN interface, there are also facilities
for updating the fi rmware from the printer”s home page.
After the initial boot sequence is performed, the number of steps will be
taken before the printer starts, which includes programming the support
chip (U30). The startup procedure can be followed on the printer’s display.
You can also follow the startup from the host provided a strap is temporar-
ily fi tted at J23 (DEBUG) on the CPU board. Connection between printer
and host should use the default serial communication setup (9600 baud, 8
bits, parity none, 1 stop bit) on the standard serial port "uart1:". For each
of the steps, either “OK” or “Fail” is returned on "uart1:". In addition,
some other useful information is also returned.
Refer to Appendix B for information on how to upgrade the fi rmware.
