how to program flash in arria ii gx dev. kit

Hi all

I'm trying to program flash in Arria II Gx Dev. Kit according to the Appendix A in Arria II Gx FPGA development kit user guide.

I'm using board update portal.

The generated hw flash file (from sof) works well. However, the sw flash file (from elf) cannot work.

In order to generate sw flash file, I'm using the following commands.

elf2flash --base=0x08000000 --end=0x0BFFFFFF --reset=0x00000000
--input=xxx.elf --output=xxx_sw.flash
--boot=$SOPC_KIT_NIOS2/components/altera_nios2/boot_loader_cfi.srec

Compared to the Appendix A, I only change the reset address.

Does anyone have any idea about this problem?

Thanks.
