Renesas RH850: iC5xxx BlueBox to iC7mini RH850 SFT trace migration

26-Jan-2024

In contrast to iC5xxx BlueBox, iC7mini only supports on-chip trace. It doesn't support streaming trace, such as LPD SofTrace. However, it is still possible to record LPD SofTrace messages into RH850 on-chip trace RAM.


Possible solution

1. Open Hardware / CPU options / Analyzer / Operation mode and select On-Chip.

Note that this works only on devices where a 32KB trace RAM is available.

2. Enable Manual Hardware Trigger via View / Analyzer / Analyzer Configuration / Options.

3. Press Configure, select the desired core trace source, e.g. SRC_PE1, and tick the following checkboxes:

  • Enabled
  • Record SofTrace
  • Record internal timestamp

This will enable unfiltered SofTrace recording, until the recording is stopped or, the trace buffer is full. Make sure that the Execution and Data trigger configuration is empty.
