Hello, I am having issues with my first use of the MangOH green and WP8548. I am trying to run through the application note [http://mangoh.io/docs/4118961\_LinCLI%20mangOH%20Green%20Fundamentals\_r4.pdf](http://mangoh.io/docs/4118961_LinCLI%20mangOH%20Green%20Fundamentals_r4.pdf) , and install Legato and configure the window for Legato use, but get the error below in the process: support@GW-Ubuntu:~/legato$ uname -a Linux GW-Ubuntu 3.19.0-33-generic #38~14.04.1-Ubuntu SMP Fri Nov 6 18:17:28 UTC 2015 x86\_64 x86\_64 x86\_64 GNU/Linux support@GW-Ubuntu:~$ cd ~/legato support@GW-Ubuntu:~/legato$ ./legato-spm --installed --update-link Refreshing installed packages ========== Install pending packages ========== Found 0 update site ========== Installed packages ========== Legato Application Framework (16.7.0.201609081601) GCC cross compiler Toolchain (1.7.3.fw\_SWI9X15Y\_07110900-wp85-wp750x-native-x86\_64-201608171142) Legato Device Image for WP85/WP75 (7.11.9.00.wpX5-201609121138) Legato Recovery Tooling for Linux (4.0.0.linux-201607191626) Legato for WP85/WP75 (16.7.0.wp85-wp75-native-x86\_64-201609121201) 5 packages installed Update latest link to SDK version 16.7.0.wp85-wp75-native-x86\_64-201609121201 support@GW-Ubuntu:~/legato$ ource ~/legato/packages/legato.sdk.latest/resources/configlegatoenv No command ‘ource’ found, did you mean: Command ‘gource’ from package ‘gource’ (universe) ource: command not found support@GW-Ubuntu:~/legato$ source ~/legato/packages/legato.sdk.latest/resources/configlegatoenv Modules: wp85, wp750x SDK Path: /home/support/legato/packages/legato.sdk.16.7.0.wp85-wp75-native-x86\_64-201609121201 Framework Path: /home/support/legato/packages/legato.framework.16.7.0.201609081601 - $LEGATO\_ROOT Toolchain Path: /home/support/legato/packages/legato.toolchain.1.7.3.fw\_SWI9X15Y\_07110900-wp85-wp750x-native-x86\_64-201608171142 - $WP85\_TOOLCHAIN\_DIR $WP750X\_TOOLCHAIN\_DIR Device Image Path: /home/support/legato/packages/legato.device.image.7.11.9.00.wpX5-201609121138 - $WPX5\_DEVICE\_IMAGE Recovery tools Path: /home/support/legato/packages/legato.recovery.4.0.0.linux-201607191626 - $WPX5\_RECOVERY No toolchain found for target ‘ar7’.

I don’t actually see a problem (other than the fact that you typed `ource` instead of `source` the first time. It is expected that the toolchains for ar7 and ar86 are not present. You don’t need them for using the wp85 in a mangOH board. ---

Hi David, Thanks! I will try running through the commands after, and see if I run into any actual issues.

> [@dfrey](#): > > It is expected that the toolchains for ar7 and ar86 are not present. You don’t need them for using the wp85 in a mangOH board. Hi Mima, I mentioned previously that those errors are actually acceptable because ar7 and ar86 are not relevant to mangOH. I think it’s obviously a bit confusing because it looks like it’s an error. ---

Thank you @dfrey dfrey, you all right. It’s only a warning that has to be ignored 😉
