Decoding error when importing CMSIS_5 using mbed cli #540

Closed TylerADavis closed 5 years ago

TylerADavis commented 5 years ago

I am encountering an error when attempting to import CMSIS_5 using the mbed CLI tools. This occurs both when I attempt to add the library to a fresh project (mbed new followed by mbed add) as well as when I try to import a project that relies on CMSIS_5 (https://github.com/uTensor/uTensor specifically).

I managed to resolve this error in the case of importing uTensor by removing the already imported CMSIS_5 files and then doing mbed update master to force the importation of the non development version. I only began encountering this error yesterday while I was able to import the library a few days back, which leads me to believe some recent change caused this break.

I have provided some system info below. If there is anything else I could provide to help with reproducing this, or if this would be better suited for the main mbed-cli repo, please let me know.

Original error message:

Hi @TylerADavis,

can you please discuss this issue with mbed-cli, first? To me it looks like the mbed cli is failing to add CMSIS_5 as a library. We need to figure out why. Later we could introduce changes to CMSIS if we can drill down the cause into this one.

Thanks, Jonatan

Seems the underlying issue has been resolved in mbed-cli, and I'm now able to import the latest version of CMSIS_5 to projects, so I'm going to go ahead and close this issue.
