Re: [partial-reconfig] SYSACE problems on ML402

["Paolo Furia" <paolo.furia@xxxxxxxxx>]

Hi,

this is the solution I found to properly open and read bitstream from Compact Flash:

 

In Xilinx Platform Studio, I go to my software application project and then on "Set Compiler Options...". On the "Environment" tab I select "Use Default Linker Script" and put 0x50 in "Program Start Address" and 4096 in "Stack Size". Using these options the system can read from Compact Flash every type of file. I copied them from a reference project found on Xilinx website (ml402_emb_ref_81).

 

Regards

You should firstly build your system and run the flash memory self test
application(EDK will create automatically) to make sure the system works,
after that, you can modify the system to the sub-module for the partial
reconfiguration system.
