send image from PC to the board via RS232C / JTAG or something.

you can send image via SD card or Ethernet, but you need more skill thank RS232C.

save bitmap into raw data and send the binary via RS232C.

how is it?

you know how to use NiosII don't you?

if you just want to send image.

send it via JTAG.

imagine you create two C code.

one runs on the PC, the other runs on the NiosII.

first one create the second C code, read the image and write the binary into the text as an array like this.

//------------------------ NiosII code ------------------

unsigned char imagedata[WIDTH*HEIGHT] = { 0x01, 0xff, 0x01 .....};

//------------------------ NiosII code ------------------

compile and run the code on your NiosII to write the data into the Flash memory.

how is it?
