hi nios users / experts,

our application has to update the content of epcs device (both fpga and application codes) dynamically.

................

2. should i program the flash myself directly or thru the epcs device?

3. are there more documentations?

any help is welcome!

thanks in advance!

regards,

kwok wong

in altera document: 'NIOS II SOFTWARE DEVELOPER'S HANDBOOK (n2sw_nii5v2.pdf)' you'll find on page 4-12 (Using Flash Devices) what you're looking for.

But there is obviously an error by altera in handling the data:

I use &#39;alt_read_flash()&#39; from EPCS and the resulting data are bit-swapped! (LSB <-> MSB)
