1 year ago @setvensxiong could you please provide more detail on how did you build your Linux image (the Linux kernel & entire rootfs)? With that information I'd like to try to reproduce your problem locally and then debug and fix it.

1 year ago Question:
What's the crash with Oops by [ECR ]: 0x00040000 => Insn could not be fetched means ? Why running user space program would also cause the kernal crash by [ECR ]: 0x00040000 => Insn could not be fetched?
Thanks!
Answers:
The cross-compile toolchain & Linux kernel & entire rootfs were build from buildroot-2022.05.2 .
Then some compile options reated with our CORE real configration were added into linux-5.4.11/arch/arc/makefile, if without such options added, the kernal start up would crash with Oops by [ECR ]: 0x00040000 => Insn could not be fetched.
The compile options added like the following:
cflags-y += -mlittle-endian
cflags-y += -matomic
cflags-y += -mll64
cflags-y += -mswap
cflags-y += -mnorm
cflags-y += -mmpy-option=8
cflags-y += -mbarrel-shifter
cflags-y += -mfpu=fpud_all
cflags-y += --param l1-cache-size=32768
cflags-y += --param l1-cache-line-size=64
Then the Linux kernel was rebuild by the cross-compile toolchain build by buildroot-2022.05.2.

1 year ago @setvensxiong thanks for the details, but may I ask you to attach .config file which you may find in the root folder of Buildroot to this issue? That file has all the information related to the Buildroot configuration and is way more convenient than setting all options manually.

1 year ago @setvensxiong OK, thanks for all your information! I've got the same problem reproduced locally even in simulation (in nSIM), which suggests that it's a purely software issue - which is good. And now we'll get to the bottom of it and hopefully soon you'll get a fix!

Stack Trace:@setvensxiong sorry for a delay, it took some time to get to the bottom of that problem and now everything is clear, thanks to @BrunoASMauricio debugging! And solution to your problem is very simple: just upgrade your Linux kernel version.
If you prefer to stay on v5.4, then just use the latest patch-version in that series (as of this writing it is v5.4.251), alternatively use another major version, but still preferably of the most recent patch-version.
Now in a bit more details. What happens, you're bumping into a pretty old bug in the Linux kernel, which was fixed a couple of years ago, see https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=3433adc8bd09fc9f29b8baddf33b4ecd1ecd2cdc. That fix was also back-ported to the v5.4 LTS almost at the same time, see https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=e242c138ae0195edcb1a8682864e766360065808 and so kernels of version 5.4.120+ already have it.
Quite unfortunately your kernel version 5.4.11 doesn't have that problem, thus you're seeing that problem. Please let us know if your problem is now resolved.

1 year ago @setvensxiong I'm closing that issue now, if you still see problems with OpenSSH please let us know and we may re-open it then.

Thanks for the reply .
I will upgrade theLinux kernel as your guide.
