RISCV tool-chain
Binaries executed by the CPU can be defined in ASM/C/C++ and compiled by the GCC RISCV fork. Also, to load binaries and debug the CPU, an OpenOCD fork and RISCV GDB can be used.
RISCV official tools : https://riscv.org/software-tools/
OpenOCD fork : https://github.com/Dolu1990/openocd_riscv
Software examples : https://github.com/Dolu1990/pinsecSoftware
OpenOCD/GDB/Eclipse configuration
About the OpenOCD fork, there is the configuration file that could be used to connect the Pinsec SoC : https://github.com/Dolu1990/openocd_riscv/blob/riscv_spinal/tcl/target/riscv_spinal.cfg
There is an example of arguments used to run the OpenOCD tool :
openocd -f ../tcl/interface/ftdi/ft2232h_breakout.cfg -f ../tcl/target/riscv_spinal.cfg -d 3
To debug with eclipse, you will need the Zylin plugin and then create an “Zynlin embedded debug (native)”.
