Are there any known issues that can cause the Cyclone V SOC to lockup on power up? We have a product where we are experience random boot failures in the field where the SOC appears to fail to boot. What I mean by this is if I probe the NOR flash pins where the bootloader is stored I see no activity at power on. The BSEL pins are properly tied high and appear to be stable at exit of POR.
We are powering the device up in the reverse order of what Intel recommends. However, the documentation just states the device may draw more power then expected at power on. The FPGA and SOC are basically powered on at the same time with the core for both powering up last.
