Flashing an LDR file seems very slow...

[LRoy]

Guys,

I have successfully flashed a labview demo to the EZ-Kit, but it takes a very long time to flash a 978k LDR file....like on the order of an hour....is that normal?

Thanks,

Larry

P.S. Here is my Flash dialog and the settings that I used...

Hi Larry,

I don't remember it taking that long the last time I did it. Did you follow these instructions?

Whoops!  I had the VisualDSP++ session set for Simulator...so it was happy to flash to a simulation, which took quite a bit longer.

When I changed the session to the actual EZ-Kit board, the flash process only took about 5 minutes for the 1 meg LDR file....cool!

Hi every one!
I can't convert dxe to ldr file. and i have read below instruction. but i can not understand.
could anybody explain detail for that instruction.
i have used ADSP BF537 EZ kit lite and labview embedded module.
Once you have a dxe file, you'll need to convert it into a standard loader format file (.ldr). This can be done using the elfloader utility found in the VisualDSP directory (\Program Files\Analog Devices\VisualDSP 5.0) and the initialization dxe file attached below. For example, the following command will create a standard 8-bit hex format file called MyApplication.ldr from the dxe file named MyApplication.dxe:

elfloader MyApplication.dxe -b flash -f hex -Width 16 -init "init_code_bf537_ez-kit_lite.dxe" -o MyApplication.ldr -si-revision 0.2 -proc ADSP-BF537 .
I have open elfloader.exe in that path but nothing happend.
thanks in advance!

Hi Seoul,

If nothing happened, then the elfloader.exe should have been successful.  The ldr file should be saved to  the current directory of the command terminal.  In the attached image, not that I call the executable from the Q:\ drive, specify the path of the dxe file from the c:\ drive, and that the resulting LDR file is on the Q:\ drive.
