how to download .srec or .bin file to nios2 board

Hi cosmosd,

With Nios II you can use nios2-download to download an elf file to your target.

Use the --help option for details, but to load and run:

$ nios2-download -g myapp.elf

If you use the jtag uart, start the nios2-terminal in a separate shell.

Regards,

--Scott

The srec method still works ( to download to RAM). The nr abc.flash won&#39;t work. Someone screwed up. The GERMS monitor has faulty code in that does not write or erase the CFI flash. Has to do with byte and word write commands(assembly code in GERMS)

First try to manipulate memory before trying to download. On the terminal type "nr -t". This should give you direct access to the GERMS monitor. Hit enter a few times. You must see a memory dump. If that does not work then something is wrong (baud rate etc...)

If that worked then try to write and read from the memory block you are targeting.

e.g. read from the location first:

m40000 <enter>

You should see a memory dump at 0x40000.

Next write something to 0x40000.

m40000:1234

Then read it again.

If it differs then your memory is not correctly interfaced. You can also try to fill the block with a fixed value

m40000-50000:1234

Dump the memory and see if a location or more has gone to cyber heaven

For all practical purposes Nios2 should download to RAM without a problem using nios-run. The only real problem is writing to flash.
