Boot form SD and in emergency mode

when i boot from SD with debian written in , it will enter emergency mode. what i used is genesys2_ariane_xilinx.new.mcs and rootfs.tar.xz download from https://github.com/lowRISC/lowrisc-chip/releases

the message is as flowed:

Hi, systemd is a bit CPU hungry to run on this hardware. The problem you are having could be starting many parallel tasks and not finishing them due to timeouts that are too short and/or lack of memory.

The FPGA board I used is Genesys2, whose memeory is 1GiB 1800Mt/s on-board DDR3. I guess the memory is enough. I want to know how to modify the timeout,and in which file. Looking forward to your reply.

Hi, You can consult generic systems documentation for timeout control, e.g.:

https://newbedev.com/how-to-change-systemd-service-timeout-value https://newbedev.com/how-to-change-systemd-service-timeout-value

Unfortunately, it is a bit painful going through the debug loop to see the effect. You can mount the SD-card locally to make these modifications.

On the whole, I find it easier to use a light-weight system, which is why I went over to buildroot for this edition. Although the Genesis has plenty of memory, it will still be crippled for CPU performance by the continuous task switching that systemd requires. Furthermore, the Linux options to run with a slower tick rate are mostly disabled nowadays.

The Ariane core is about 15% slower than Rocket for unknown reasons.
