Make debugging easier by printing relevant errors #35

Open ShellCode33 opened 5 years ago

ShellCode33 commented 5 years ago

Hi ! Thanks for this amazing tool ! I came across an error and to be honest, debugging arm_now was an absolute nightmare... I spent almost 2 hours digging into the code just to realize the FS wasn't big enough... This PR improves errors printing and should help future users to understand what's wrong with their setup

Hey @ShellCode33 there is issue with ur PR (Conflicts)

ShellCode33 commented 5 years ago

It was indeed in conflict, I included a commit in the PR which shouldn't have been there. Should be ok now.

ShellCode33 commented 5 years ago

This is not related to this PR but more to this one #36, you are probably using a pretty old version of qemu... Can't you upgrade it ? Otherwise the thing to do is to check qemu's version beforehand and use the appropriate parameter, which is kind of ugly :/

SakiiR commented 5 years ago

Sorry @ShellCode33 I don't understand, what is the new syntax ? --redir or -nic user,hostfwd=tcp::8080-:80

Here is my version of qemu-system-arm: 

- tmux % qemu-system-arm --version

Oh ok I see ! You are still using the old qemu's -redir, do not clone my repo as is, it only contains this PR, not the other PR I've made about the ports redirection fix. But again, this PR is not about port redirection, it's just an errors printing improvement

Just to be clear :
