Hi all,
We have a custom board containing DM6446 DSP, and we need to transfer the
data over USB in both directions.
Meaning, my PC application will act as HOST and DM6446 EVM configured as a
Gadget Device.
Initially HOST will send some configuration data which DM6446 has to receive
and configure other peripherals say FPGA
At the end of some operation, the hardware will store the huge data(around
2GB) into the available DDR2 memory,
Which I need to transfer to host using USB2.0
I have 2 queries here
1) Which type of Gadget device should I use? I mean USB Gadget Ethernet /
File backed storage/Serial
2) I tried to Configure EVM as Gadget Serial and the Data rate is < 1 MB
which is worst for me.
I have used default MVLinux401 came along with DVEVM. If I apply the
latest LSP patch from TI,
Will it make any difference in the performance?
3) Is there anybody who has used Gadget serial and what is the max data rate
achieved?
Need your support!
Thanks and Regards
Nitin Joshi
