Dear Matthias and all:
Thank you for your advice.
first you should make sure that the FPGA bitstream is also correctly on the SD
card,
use the u2_flash_tool to copy both files to the card.
You should use
http://code.ettus.com/redmine/ettus/attachments/70/u2_rev3-20100603.bin as the
FPGA image.
Your mean is that nedd to write "txrx.bin",
before write "txrx_wbx_raw_eth_20100608.bin" ?
Your mean like this?
-----
$ sudo u2_flash_tool --dev=/dev/XXXX -t s/w txrx.bin -w
$ sudo u2_flash_tool --dev=/dev/sdd1 -t s/w xrx_wbx_raw_eth_20100608.bin -w
-----
I'll try this tomorrow!
More information here:
http://gnuradio.org/redmine/wiki/1/USRP2UserFAQ#How-do-I-change-the-firmware-and-FPGA-code-on-the-SD-Card
Try the following:
(check with the command "dmesg" to to see which device is used for the SD card,
it may change every time you insert the card)
$ dmesg
You will see something like
...
sd 0:0:0:0: [sdd] 3842048 512-byte logical blocks: (1.96 GB/1.83 GiB)
usb-storage: device scan complete
sd 0:0:0:0: [sdd] Write Protect is off
sd 0:0:0:0: [sdd] Mode Sense: 03 00 00 00
sd 0:0:0:0: [sdd] Assuming drive cache: write through
sd 0:0:0:0: [sdd] Assuming drive cache: write through
sdd: sdd1
sd 0:0:0:0: [sdd] Assuming drive cache: write through
sd 0:0:0:0: [sdd] Attached SCSI removable disk
athe end of the output when you insert the card, so in this example sdd is
correct. Be careful that the device is correct.
Then do
$ sudo u2_flash_tool --dev=/dev/sdd -t fpga u2_rev3-20100603.bin -w
$ sudo u2_flash_tool --dev=/dev/sdd -t s/w xrx_wbx_raw_eth_20100608.bin -w
I think I found your problem after writing this:
you have a filesystem on your SD card, because you use /dev/sdd1.
You have to use /dev/sdd with the u2_flash_tool in order to correctly flash the
card,
the files must be written directly on the beginning of the card
(and make sure that /dev/sdd is the correct device first, it will otherwise
overwrite your boot sector or whatever...)
If you used a new card, you definitely need to put both FPGA and firmware on
the card.
When I try this command, u2_flash_tool return error.
>> --
>> sudo u2_flash_tool --dev=/dev/sdd -t s/w xrx_wbx_raw_eth_20100608.bin -w
>> --
What error does it give? Maybe the device has changed from /dev/sdd to something else.
You can check with "dmesg".
If
$ sudo u2_flash_tool --dev=/dev/sdd1 -t s/w xrx_wbx_raw_eth_20100608.bin -w
works, then
$ sudo u2_flash_tool --dev=/dev/sdd -t s/w xrx_wbx_raw_eth_20100608.bin -w
must also work.
I can't use "sdd".
Please see this...
--------
~/Desktop/gnuradio_fw$ sudo ./u2_flash_tool --dev=/dev/sdd -t fpga
u2_rev3.bin -w
Traceback (most recent call last):
File "./u2_flash_tool", line 111, in <module>
main()
File "./u2_flash_tool", line 98, in main
and verify_flash(offset, filename, options.dev))
File "./u2_flash_tool", line 35, in verify_flash
dev_data = dev.read(len(file_data))
IOError: [Errno 5] Input/output error
~/Desktop/gnuradio_fw$ sudo ./u2_flash_tool --dev=/dev/sdd1 -t fpga
u2_rev3.bin -w
---------
So I try this
---------
$ sudo u2_flash_tool --dev=/dev/sdd1 -t fpga u2_rev3-20100603.bin -w
$ sudo u2_flash_tool --dev=/dev/sdd1 -t s/w xrx_wbx_raw_eth_20100608.bin -w
--------
After that, my USRP2's LED is not light up (all of 6 LEDs light OFF)
Regards,
youhei
