help for C6474 emulation problem

Dear all:

I use BlackHawk USB-560BP emulator to emulate our custom C6474 board! But something really troubles me!

1. I can't connect the target board under CCSv4, but with CCSv3.3, the connection works well! I installed the emulator driver http://www.blackhawk-dsp.com/downloads/EMU_ByEmulator.aspx ! So do I need to install another driver for CCSv4? From the target configuration, BH-USB-560BP Emulator is available!

2. Under CCSv3.3,  after the connection, once I load the DDR test program downloaded from spectrum digital C6474 evm, an error "Trouble Reading Memory Block at 0x800000" appears! But with our 560PCI emulator, the load of the program works well, the problem with the PCI emulator is when the CPU tries to test the memory from 0x80000000 to 0x8fffffff, the emulator disconnects because of power failure! I wondered why the usb emulator can connect the target but can't load the program into the target while the PCI emulator can. And why the PCI emulator encouters the disconnection becaus of the serious power failure? The DDR is the same as the Spectrum EVM and the same gel is used!

3. As to the gel file, I found that from the gel for the Spectrum EVM, the L2 address and size may be configured not that correct! The size of L2 can't be 0x180000 for all the three cores! And as to the PLL Controller Divider, from the C6474 datasheet, only PLLDIV11 and PLLDIV13 can be programmed, why the EVM use PLLDIV4 and PLLDIV5?

Thanks all for your reply!
