Thanks! It started working after I added RCC_APB2ENR_AFIOEN. I attached
both chopstx board and GNUK_USB_DEVICE_ID patches. The board name was
changed before it has been put into production.

2048-bit RSA is working fine, however when I tried using ECC (NIST
P-256) with current Gnuk-1.1.x, gnupg-2.1.7 and libgcrypt-1.6.3, I have
always ended up with:
> gpg: KEYTOCARD failed: Invalid value

Am I missing something here?
