dagrom
dagrom
is a software utility to configure the FPGA on Endace DAG cards. The following table lists
dagrom
options.
Option
Description
-a,--alternate-half
Use alternate (stable) half. [Default is current half.] Factory / User.
Note:
Not applicable to DAG 7.4S, 7.5G2/G4, 9.2X2 or 9.2SX2 .
-A,--entire-rom
Entire ROM. [Default is current half only.]
Note:
Not applicable to DAG 7.4S, 7.5G2/G4, 9.2X2 or 9.2SX2 .
-b,--swid-rom-check
Check if there is a SWID on the ROM.
-c,--cpu-region
<region>
Access CPU region: c=copro, b=boot, k=kernel, f=filesystem, a=all.
--continue
Continue on erase error.
-d,--device <device>
DAG device to use.
-e,--erase
Erase ROM. [Default is read.]
-F,--disable-cfi-fast
Disable fast program option for CFI mode. Use only on the advice of Endace.
-f,--file <filename>
File to be read when programming ROM. There are multiple FGPA images per DAG
card, covering the different versions, ERF, BFS, DAM etc.
--force
Force loading firmware. Not recommended unless absolutely necessary - use only
with extreme caution.
Caution:
May prevent DAG card operation or even damage the DAG card.
-g,--rom-number <rom>
Access specified ROM controller. [Default is 0.]
-h,--help -?,--usage
This page.
-i,--halt-ixp
Halt the embedded IXP Processor (DAG 7.1S only).
-I,--incr
Increment ROM. [Default is read.] Use only on the advice of Endace.
-j,--swid-rom-check-key
<key>
Check the ROM SWID key with the one supplied.
-l,--hold-bus
Hold PBI bus from XScale (DAG 3.7T only).
-m,--swid-key <key>
Hexadecimal key for writing the Software ID (aka SWID).
-n,--fpga-number <FPGA
number>
Specify which FPGA to load the specified image into on next power cycle. Default
FPGA number is 0.
-o,--swid-rom-read
Read SWID from ROM.
-p,--program-current
Program current User 1 Xilinx image into FPGA.
Caution:
Do not use with DAG 7.4S, 7.5G2/G4, 9.2X2, 9.2SX2 DAG 9.2X2, 9.2SX2, see
-q
below.
-q,--image-number
<image number>
Specify the image number for operations (
-w
,
-r
,
-y
,
-e
).
•
0.factory image
•
1. user image 1,
•
2. user image 2
•
3. user image 3
When used with the
-r
or
-w
options,
-q
changes into which slot the image is
loaded.
When used without the
-r
or
-w
options,
-q
does not change the image itself,
rather it sets the "boot next" flag.
Note:
Use with DAG 7.4S, 7.5G2/G4, 9.2X2, 9.2SX2 only.
-r,--reprogram
Reprogram ROM (may imply erase and write).
