No console output after bootconsole disables #68

Closed suedadam closed 6 years ago

I'm having a similar issue to #44 . I'm trying to run it with Spike.

Here's the console log:

The default serial driver is the one that works best on the Hifive Unleashed hardware, but it unfortunately does not work on spike. To get the old serial driver, which does work on spike, enable CONFIG_HVC_RISCV_SBI in conf/linux_defconfig.

That worked! Thanks 💯

I encountered the same problem, but it can't help after i set CONFIG_HVC_RISCV_SBI=y.

jim-wilson commented 6 years ago

@yonghaoXuGit Are you running on spike? Did you rebuild the kernel after setting CONFIG_HVC_RISCV_SBI? Did you verify that the kernel .config file in the build tree has CONFIG_HVC_RISCV_SBI set?
