AGLN010 degin not work

Hi
I am a new user in the FPGA and using Librero soc software.
I have purchased the AGLN-NANO-KIT and wrote a VHDL code and programed the code into the KIT and everything works fine.
But in project I am using AGLN010V2 and not AGLN250V2 that on the KIT.
I have purchase the AGLN010V2 chip and built a circuit similar to the one on the KIT. Using core volt of 1.5v and IO voltage 3.3v and JTAG periphery. scheme is attached
My problem is:
the same design scheme (hdl code) works in the AGLN-NANO-KIT but not working in my board !!
what could be the reason ?
i notice the almost all IO in bank 0 is in 1 logical state where in the AGLN-NANO-KIT they are 0 logical state.
regards
yossi

    what could be the reason ?

    That’s a wide open question when you’ve provided very little info to go on. I haven’t used igloo nano’s but I’ve used regular Igloos and I think they are similar.
    Based on what you’ve revealed I would guess either bad schematic (the picture was unreadable), bad code, Bad pin assignment, or bad assembly.
    But seriously, the Igloo IO have pull-ups enabled (annoying) when blank so it appears your Nano isn’t actually Being flashed. Could be your clock isn’t running.
    I assume you are using Libero prior to 12.0 since Igloo isn’t supported after 11.9.
    How are you burning it? We use flashpro 3’s and 4’s with flashpro software but occasionally I’ve programmed From within Libero.
    Have you checked that your clock is running?

    yes using librosoc 11.9
    using flashpro3 and getting message all was flashed good
    the clock is working
    can you send a minimum schem of only  igloo nano jtag and power ?

    I've never used a nano.
    Squinting at the poor schematic image, it appears that your igloo symbol is incorrect. Th UC36 is a BGA package so pins should be number A1-F6 not 1-36.
     
    I guess you can number pins however you want as long as the schematic and layout agree, but I think this is very bad practice which could very well be the source of your problem. It certainly makes it impossible ror someone else to review the design as it doesn't match the documentation.
