help: niosII and pof/sof

Thanks dsl

I tried your suggestion, but but was unsuccessful: Here's what I did -

1.) create basic nios2 system

- OnChip ROM, 32K - initialized from onchip_rom.hex

- OnChip RAM, 32k - initialized from onchip_ram.hex.

- nios II/f, data cache disabled, no JTAG debug support.

--- reset vector pointed to address 0x0 of ROM

--- exception vector pointed to address 0x20 of ROM

--- break vector pointed to address 0x20 of ROM

- sysid block

- system timer block

- 1 PIO connected to a 10 pin debug header I have on board.

2.) Use Eclipse SBT to create a basic application which infinitely loops just incrementing an 8 bit count and does an AVALON_PIO_WR to the PIO block. (there's a usleep(10000)) at the bottom of the loop.

3.) compile Nios SBT

4.) make mem_init_generate to create onchip_ram.hex (all zeros) and onchip_rom.hex, from the elf and then add the mem_init.qip file to my QII project.

5.) build the system in QII

6.) download the .pof file to my device.

7.) attach a logic analyzer to my debug pins (PIO) and they're not toggling.

--------------------------------

going to keep working on this. I really need to get NiosII working on this board.
