Hi,

When I put the kernel image and install the USB Gadget on a custom board based on BF526 with 64MB SDRAM,  everything works fine.  When  I put the same image on a board with 32MB SDRAM am getting a response like this(please check the log colored in Red.).  Is it something todo with MUSBcore?  How can I correct it?

I have attached the full log file.

Is the board with 32MB SDRAM exactly the same as your customer bf526 board with 64MB?

Yes, I just replaced the 32MB SDRAM with 64MB SDRAM to run the VDSP driver and on the same board I tested the USB on linux platform and got the above result.
