Hi,

 

i need assistance with the booting of the named eval-board. I did already flash the dsp with the AudioLoopback example from the support package.

 

I did it the following way.

 

build the dxe file from the example files via the debugger. used the dxe file in the debug directory.

used elfloader:

elfloader.exe -b flash -f hex -width 16 -dmawidth 8 -init audioloop.dxe -o audioloop.ldr -si-revision 0.1 -proc ADSP-BF592-A

 

then flashed via:

cldp -proc ADSP-BF592-A -emu KIT -driver "C:\Analog Devices\ADSP-BF592_EZKIT-Rel1.0.0\BF592_EZ-Kit_Lite\Blackfin\Examples\Device_Programmer\serial\bf592_m25p16_dpia.dxe" -cmd info -cmd prog -erase affected -format hex -file audioloop.ldr -cmd compare -format hex -file audioloop.ldr

 

The problem that occurs is that the dsp uses the flash but does not start properly. Sometimes it works if use the reset button on the eval-board to start the code, sometimes it starts immediately after powering the board and sometimes nothing happens at all.

Is the powering via usb necessary - i guess not?

 

What do i miss? Thanking you in anticipation.
