前回の続き。前回はQEMUで動作させることができるようになったので、Spikeと自作RISC-V ISSで動作を確認していく。 あらかじめ断っておくがSpikeは今回のビルド環境に対するサポートはしていないので動作しないことは予想通りなのだが、一応確認していこう。
これまでの経験上Spikeで動かすためには以下のようにする。

ここで停止する。これは予想通り。次に自作RISC-V命令セットシミュレータで確認する。とりあえずこれで行けるはず。

同じようにここで止まった。QEMUを見ながら、修正していこうかな。これまでの経験上freedom-u-sdkではSpikeで動かすときはconfigでCONFIG_HVC_RISCV_SBI=yを有効にしなければならなかった。
.config
# CONFIG_SERIAL_FSL_LPUART is not set # CONFIG_SERIAL_CONEXANT_DIGICOLOR is not set # CONFIG_SERIAL_DEV_BUS is not set # CONFIG_TTY_PRINTK is not set CONFIG_HVC_DRIVER=y CONFIG_HVC_RISCV_SBI=y # CONFIG_VIRTIO_CONSOLE is not set # CONFIG_IPMI_HANDLER is not set # CONFIG_HW_RANDOM is not set # CONFIG_R3964 is not set
あれ、おかしいな有効化されている。。。トレースを取って確かめてみようか。。。
