Shakti C Reference Platform (
Shakti C Reference Platform is a reference platform based on arty a7 100t for the Shakti SoC.
Shakti SoC is a SoC based on the Shakti C-class processor core. Shakti C is a 64bit RV64GCSUN processor core.
For more details on Shakti SoC, please see: https://gitlab.com/shaktiproject/cores/shakti-soc/-/blob/master/fpga/boards/artya7-100t/c-class/README.rst
For more info on the Shakti C-class core, please see: https://c-class.readthedocs.io/en/latest/
shakti_c machine supports the following devices:
- 1 C-class core
- Core Level Interruptor (CLINT)
- Platform-Level Interrupt Controller (PLIC)
- 1 UART
shakti_c machine can start using the standard -bios
functionality for loading the baremetal application or opensbi.
Boot the machine¶
Shakti SDK can be used to generate the baremetal example UART applications.
$ git clone https://gitlab.com/behindbytes/shakti-sdk.git $ cd shakti-sdk $ make software PROGRAM=loopback TARGET=artix7_100t
- Binary would be generated in:
You could also download the precompiled example applications using below commands.
$ wget -c https://gitlab.com/behindbytes/shakti-binaries/-/raw/master/sdk/shakti_sdk_qemu.zip $ unzip shakti_sdk_qemu.zip
Then we can run the UART example using:
$ qemu-system-riscv64 -M shakti_c -nographic \ -bios path/to/shakti_sdk_qemu/loopback.shakti
We can also run OpenSBI with Test Payload.
$ git clone https://github.com/riscv/opensbi.git -b v0.9 $ cd opensbi $ wget -c https://gitlab.com/behindbytes/shakti-binaries/-/raw/master/dts/shakti.dtb $ export CROSS_COMPILE=riscv64-unknown-elf- $ export FW_FDT_PATH=./shakti.dtb $ make PLATFORM=generic
fw_payload.elf would be generated in build/platform/generic/firmware/fw_payload.elf. Boot it using the below qemu command.
$ qemu-system-riscv64 -M shakti_c -nographic \ -bios path/to/fw_payload.elf
