Q1:I am currently using DM648 in CCS3.3. In the gel file of DM648 EVM board, the following code appears many times:
// Only in DVR mode
if( BOOTCFG & 0x40000)
{
... //configure several registers
}
I look up the register BOOTCFG in datasheet, found that the 18 bit is "reserved". So what is the functionality of this bit? Where does this bit read value?
What's the difference of the DSP's behavior between DVR and NON-DVR mode??
Q2: On my own DM648 board, when I pull up the DEVICE_ENABLE/AEA20, the board keeps reseting. WHY??
