Issues Installing Legato and Using CLI

mangOH Green

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 , and install Legato and configure the window for Legato use, but get the error below in the process:

Has anyone seen this before?

Thanks,

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.

Hello i am having the same issue while trying to use Legato CLI, when i run :
~/legato$ source ~/legato/packages/legato.sdk.latest/resources/configlegatoenv

I got the errors:

No toolchain found for target ‘ar7’.
Unable to find compatible cross-build toolchain for target ‘ar7’.
No toolchain found for target ‘ar86’.
Unable to find compatible cross-build toolchain for target ‘ar86’

Could anyone help me please ?

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 :wink:
