address matched to blocksize (TMS470/TMS570)

Ref: 0353
What does the warning "Entered address has been corrected to match the current blocksize" mean?

This error occurs if the base address of the RAM and/or peripheral address space is not configured for the current device.

You can configure the base address(es) by the following PRACTICE commands:

How to avoid "TARGET FIFO OVERFLOW" error messages in the trace window?

  • Increase the traceport data throughput via RTP.PortClock.
  • Increase the frequency of the system clock (HCLK) in relation to the CPU clock (GCLK).
  • Reduce the size of the RAM area to be traced via RTP.TraceMode.RAM<x>.SECTion<y>.Size.
  • Include some 'nop' operations in the relevant parts of your target’s executable code.
