how to port nios2 to stratix dsp s80 board?

Hello ffone13,

If I understand you correctly the only thing which does not work with your Nios II design on your EP1S80 board is the flash. Is that correct? Did you add the following line in the source-code of “altera_avalon_cfi_flash_table.c” as it was described in cfi (http://www.niosforum.com/forum/index.php?act=st&f=17&t=455)?

altera_avalon_cfi_flash_table.c”, line 439:

/*

* Check for 8/16 bit in byte wide mode

*/

// Reset the device

IOWR_8DIRECT(flash->dev.base_addr, 0x00, 0xF0);

alt_write_flash_command_16bit_device_8bit_mode(flash->dev.base_addr, 0x55, QUERY_MODE);

Inserting a reset was solution in my case.

Bye,
