    BYTEMAN got a reaction from RichardV in CMOD A7 Bootloader for SDK   
    Hi @RichardV, I'm just working on this board and on a design that have:
    - MicroBlaze
    - UART Lite
    -Interrupt controller connected to the MicroBlaze in order to handle the UART by interrupt
    - Some GPIO input and output managed from the MicroBlaze
    - Some RTL logic written in VHDL with some line interfaced to GPIO of the MicroBlaze
    This design will act as a base to start in developing with MicroBlaze and this very nice evaluation board from Digilent.
    Actually I've written a post on some things about this design, if you like we can work together to write a full tuturial, step by step, I hink that can be useful for better understand how to proceed and give a general starting point for other design.
    Post link: my post link
    Cheers!

    @twinvalleytechdear friend if you are just starting with FPGA development I can suggest to use a simple and cheaper Cmod A7-35t development board. If you like to practice with a softcore MicroBlaze and interact with the fabric logic inside the FPGA, coding with VHDL/Verilog this board is very interesting and give an useful starting point. There are plenty of good tutorial around here and when get some feeling you can step toward to a more complex board.
    Basys 3 (I've never used it) have a slightly higher cost, but more peripheral around the FPGA and then you can avoid to breadboard around the Cmod A7-35t but is up to you. Actually I've start to use the Cmod A7-35t, is very small and lightweight and a very good to start with basic IP Block Design, MicroBlaze testing, RTL with VHDL/Verilog coding, for my little experience a great board.
    Bye

    Hello @BYTEMAN,
    Taking a look at this thread, you may need to re-generate your BSP sources, or potentially delete it and create a new one. I would also make sure that all of the SDK settings (I'm not certain if you have changed any) are on their default settings.
    Thanks,

    Hi @BYTEMAN,
    I'm not certain on the differences between the two interrupt controllers, you will likely need to contact Xilinx to see if they have any additional thoughts or concerns on this.
    As for the SDK debugging behavior, according to this Xilinx site, the GDB mode is depreciated, so you will likely want to instead use the "Launch on Hardware (System Debugger)" option instead for some better results, as this Xilinx forum thread seems to indicate as well.
    Thanks,
    JColvin
