Interestingly, I also found that the conf_done is showing up error when the re-config is triggered with the application address 0x0. Normally it should load the Factory FPGA, right?

Hello,
While debugging with the AS interface of the FPGA, I had found that the SPI sends the address as 24 bits even though the EPCQ used is 256.
For example, to know the behavior at FPGA configuration , I tried an address 0xABCDEF98 and confirmed with signal tap that the address is written correctly at the data_in port of the RSU module!
Surprisingly, the data in SPI bus is 0x0b, 0xAB, 0xCD, 0xEF 0x00 ... Seems the EPCQ 256 controller communicates 24 bit address, instead of 32 bit.
Does this mean that I forgot to use some options for the FPGA, to enable 4 byte address access of the EPCQ-256 ??
Thanks in advance for your advice.
