Single-core tutorial: Can not launch Linux on vcu118

[andy39866821]

I am trying to run make fpga-run-linux in single core design tutorial, but it failed when mounting root filesystem. Here is the message in minicom when launching Linux.

Everything in the previous step is fine, make fpga-run can generate "Hello ESP" in minicom as tutorial said. Here is my hardware and setting. Is there any wrong with my config setting?

OS: CentOS7
FPGA: Xilinx vcu118

esp config: leon3, not used cache, other are default value.

Makefile setting in esp/socs/xilinx-vcu118-xcvu9p/ :
### Xilinx Vivado hw_server ###
FPGA_HOST ?= localhost
XIL_HW_SERVER_PORT ?= 3121
# IP address or host name of the host connected to the FPGA
UART_IP ?=
UART_PORT ?=

hi @andy39866821

This error message indicates that you did not build correctly the template for the root file system. This could happen when some compilation step of buildroot for RISC-V fail due to missing system packages or libraries.

Please run again the toolchain scripts, skip the steps for baremetal and Linux compilers (GCC), but repeat the step for sysroot. See the setup guide for details.

Look carefully at the messages on the shell while buildroot executes and make sure you have installed all required packages

Once the sysroot template has been rebuilt correctly, enter the design folder for VCU118 and run make linux-distclean to remove the incomplete sysroot folder. Next run make linux -j 8 again to recompile Linux with the correct root file system embedded.

Please let us know if you have additional issues.
