Hi All,


Here I designed a custom  board consisting of 2 TS201 and 1 Stratix-III FPGA, and the flash used At49bv040b(same as EZ-Kit board).


I have writted a LED blinking code to test my system. The power-up booting succeed only twice. Most time, it seems stucked at the time of downloading the boot kernel.


After power-up booting failed, I used emulator connecting my board to check the DRAM memory(The DSP seems reseted by emulator connecting). Found that the boot kernel code from address 0x00 to 0x07are always wrong(one word less or more), followed by a few part of right code, and then followed by all wrong codes.


Can someone please tell me, where the problem exactlly happened?How can I fix it?


Thanks and Regards,
