DesignWare ARC AXC003 CPU Card User Guide 

Pre-Boot 

 

 

Synopsys, Inc. 

Version 6323-018 

 

 

May 2017 

As an example Figure 37 shows how the pre-bootloader loads an image from the SPI-flash 
on the ARC SDP Mainboard to the DDR3 SDRAM on the AXC003 CPU Card. 

 

Pre-Boot Mechanism 

 

 

The  pre-bootloader  uses  the  seven-segment  displays  on  the  Mainboard  to  show  status 
information. The left character shows the CPU number that is also used in the debugger as 
listed in Table 33. If loading of an image is bypassed (SW2501[3]), a dot is displayed next to 
the CPU number. 

The right character shows an error code as explained in 

Table 34 o

n page 77.
