In the tutorial

Hi

in wsl

when I used it
Install qemu-system-arm and GNU CC toolchain for ARM:
sudo apt-get install -y qemu-system-arm gcc-arm-none-eabi build-essential subversion

I got this result in wsl

hussam@DESKTOP-8EVN1O6:~$ sudo apt-get install -y qemu-system-arm gcc-arm-none-eabi build-essential subverion
Reading package lists… Done
Building dependency tree
Reading state information… Done
E: Unable to locate package subverion
hussam@DESKTOP-8EVN1O6:~$

Is this correct or is there a problem

Hello @hussam,
It seems you forgot a character in your command, it should be:
sudo apt-get install -y qemu-system-arm gcc-arm-none-eabi build-essential subverSion

If you try with the “s” I think the package will be found.

Thanks Alex
It worked

when I use this:

hussam@DESKTOP-8EVN1O6:~$ mkdir -p /mnt/c/Users/${USER}/src/tuto-from-scratch
mkdir: cannot create directory ‘/mnt/c/Users/hussam’: Permission denied

I did not have permission to create the file

What do I do???

Hello @hussam,

This issue is not related to the tutorial. You have to make sure you have the permission on the directory you are using. You can run the command ls -l to see who is the owner of the directory and what are the permission.

I did all the steps in Create a MicroEJ Firmware from Scratch but had a hard time understanding this note

Hello @hussam,

This note explains how to apply a patch. What don’t you understand about it?

Alexis

I did not find the patch file

Linker. Patch

This is the result when we use the following command:

qemu-system-arm -Mlm3s811evb -nographic -kernel gcc/RTOSDemo.bin
