What did you do?

compile with

GOOS=linux GOARCH=mips GOMIPS=softfloat go build -ldflags "-s -w"  -o probe-client ./probe-client.go

What did you expect to see?

run success

What did you see instead?

Illegal instruction

Does this work in 1.15?
Can you figure out what the illegal instruction is? That error looks like it is coming directly from the OS, not from the Go runtime. Which makes me think it is very early in startup, before the Go runtime can install the SIGILL handler (or, less likely, the OS is not delivering SIGILL correctly).
Can you run under a debugger and see where it stops?

isa : mips1

If this is not lying, this ISA is really old. Go requires newer ISA (MIPS32r1+) to run.

Timed out in state WaitingForInfo. Closing.

(I am just a bot, though. Please speak up if this is a mistake or you have the requested information.)
