Java Card returning 6F00 while installing applet

QUESTION

Java Card returning 6F00 while installing applet

Asked 2018-May-17 at 08:02

I have a J3H081, SCP 02, T=1, GP 2.2.1, JC 3.0.4 java card and want to install applets onto it.

Unfortunately I get on every *.cap file I tryed error 6F00 (Command aborted - more exact diagnosis not possible (e.g., operating system error)).

I tried the pre-compiled *.cap from here: https://github.com/LedgerHQ/ledger-u2f-javacard, built it myself with JavaCard v3.0.3 SDK, from AppletPlayground I tried the OpenPGPApplet and YkneoOath. All result in an 6F00 error while installing.

The only applet I was able to install was the pre-compiled AlgTest_v1.7.4_jc222.

Because you probably don't have the features necessary for those applets and applet initialization throws an exception which is not handled. This specific case seems to be no support for ECC.
