7214 - Avant-E: How to enable RISC-V software debug for Avant-E device
Description:
User is required to implement soft JTAG to enable RISC-V debug in Avant-E early silicon.
Solution:
Please follow below step to enable debug with Soft-JTAG. The pin assignment is based on Avant-E Evaluation Board.
- Create an Avant-E RISC-V RX based SoC Project from Propel Builder/Propel SDK
- Choose board template - Avant-E Evaluation Board
- The Avant-E board template should have the following automatically setup in place
- Enable RISC-V debug port in Propel Builder
- In RISC-V IP wizard, choose Debug enable
- Enable RISC-V debug port in Propel Builder
