[question] how to run `rv-virt:knsh32` with qemu

[yf13]

I built nuttx with tools/configure.sh rv-virt:knsh32 && make.

Followed the boards/risc-v/qemu-rv/rv-virt/README.txt, I tried qemu-system-riscv32 -semihosting -M virt,aclint=on -cpu rv32 -smp 2 -bios none -kernel nuttx -nographic but there is no nsh> prompt appears.

after doing make export from nuttx folder then make import in apps folder, it works now.
