Yes, you can program anything you want in your flash. You need an EDK project that has the the flash interface. Then in EDK you go to "Device Configuration" -> "Program Flash Memory".

Re: Trying to make LED to blink rapidly on Microblaze(C lang
I didn't look through you code but I'll try to suggest you how to learn to do it.
When you use the wizard to generate the platform you also get a test a application which tests your peripherals. One of them is the LEDs GPIO. Have a...
OK. Yes, the processor will spend some time to save and restore the context, that is registers that will be affected in interrupt. So you can't rely on instant interrupt servicing. That holds true for any processor in this world.
Now that I understand better what you try to do I suggest to use...
Apparently you want a precise counter but you don't really want to let the timer to do it. So instead of keeping the counter value in a variable how about letting the timer run and look for it's value only? Or better, generate an interrupt when you need to do something (something more than just...
My project is basically a LED stick that can detect the hand motion and display a floating image.
* 32 leds capable of displaying 32 vertical pixels
* Three axis accelerometer
* HID USB device, no drivers necessary
* HID USB bootloader, no drivers necessary...
Re: VHDL/module get different simulation result as a compone
Your stimulus are not exactly the same. When you simulate the stand alone component your stimulus which are probably synchronous with the clock are applied a little before the active edge of your clock (depending on your testbench...
edk create custom board
C:\EDK92\doc\usenglish\psf_rm.pdf (assuming you have EDK 9.2)
I highly recommend to use an existing xbd from one of the demo boards which is closer to your custom board as a starting point.
Modbus can work over serial or Ethernet.
If you need to implement MODBUS over a serial connection then all you need is a UART and a processor (NIOS is very good)
If you need MODBUS-TCP then you need an Ethernet port instead of UART.
