Unaligned access from DSS CM4 could cause data integrity failure and hang

Details

The DSS HWA CM4 cannot perform an access to an address space outside its subsystem, which is:

  • Not aligned to the 32 bit boundary OR
  • Not a multiple of 32 bit such 8/16 bit access

This includes and is not limited to DSP L2, DSS L3, and MSS L2 spaces.

Workaround

Ensure address is 32 bit aligned and accessed in multiples of 32 bit.

DMA the data from L2/L3 to a location inside the HWA CM4 Subsystem and then access from CM4.
