Hi,
My customer started development with the DM648.
He previously used the C6202 / C6413, and chose the DM648 to upgrade them.
He was trying to port code based C6413, but DM648 has difference between C64x+ and C64x.
After reset, DM648 is in supervisor mode. So I think the control register are available for access in supervisor mode.
But I can't write to CSR.
when the below line is executed, it is not actually reflected
CSR |= 0x00000001;
Is there something else for control register access?
