Table 1-33: Mode Switch S2 Settings
With the mode set to JTAG 101, the ML605 will not attempt to boot or load a bitstream from
either of the Flash devices. If a CompactFlash (CF) card is installed in the CF socket U73,
System ACE CF will attempt to load a bitstream from the CF card image address pointed to
by the image select switch S1. With no CF card present, the ML605 can be configured via
the onboard JTAG controller and USB download cable as described above.
With the mode set to either Slave SelectMAP 110, or BPI Mode 010, the FPGA will attempt
to configure itself from the selected Flash device as described in
XL.
Note:
System ACE to boot at power-on if it finds a CF card present. In order to boot from BPI Flash U4 or
Xilinx Platform Flash (U27) without System ACE contention, S1 switch 4 must be OFF.
