JavaCard OS

I was sending test commands to my applet on the card when it just stopped working.

The card returns SW 6D00 (Invalid INS) whenever I send a SELECT APDU or any other GP or ISO command.
If I use a CLA that's not GP or ISO it returns SW 6E00 (Invalid Class).

Code: Select all

A>> T=0 (4+0000) 80F20000 7F
A<< (0000+2) (18ms) 6D00
A>> T=0 (4+0000) 00A40400 00
A<< (0000+2) (10ms) 6D00
A>> T=0 (4+0000) 90000000 00
A<< (0000+2) (18ms) 6E00

JC version is 3.0.4
GP version is 2.3
Using https://github.com/martinpaljak/GlobalPlatformPro to send APDUs

Has anyone seen this before?

Maybe you need to check you card reader and your java card are connect successful, and the card is on the OP_READY status.

How would I check that the card is in the OP_READY status?

I don't think the card reader is the problem since it still works with other cards.

Where do you get the card from ?

What is the brand and model of the card ?

Also, can you post the GP commands you issued with GlobalPlatformPro ?

Can you issue

Code: Select all

java -jar gp.jar -i

to get a printout of the information from GlobalPlatformPro ?
