Hello,
I couldnt find the right spec explaining "C482XXYY" in Header.cap, how it should be calculated,
this answer below helped me navigate, but for Method.cap loading - it still fails
https://community.oracle.com/tech/developers/discussion/1753814/globalpaltform-load-command-data-field
I've written this loader:
https://pastebin.com/pSXeDYyS
Every component in CAP file is in separate APDU with LOAD instruction.
First 5 is loaded successfully with DATA=00, SW=9000, however on Method it fails.
As you can see from my script, I've fixed Descriptor size to 0000 in Directory field.
And in Header C482xxyy, where xxyy is calculated properly, which is a sum of
all size fields in Directory, e.g.
016a = 0011+001f+000c+001e+0042+0018+006d+0032+0017+0000+0000
Question: Can't figure out why Method LOAD fails? By checking GP 2.1 spec, it doesnt
help me understand the problem.
Concatenated components to < 255 block size also fails,
only separate components work for LOAD.
