About the Compatibility of GNUK 2.1 Firmware with ST Link v2

[D Tibrella]

Hello, there is the latest test.

> I haven't tested GCC 13.2 yet.  It may be the cause.  I'll test when
it will be available in Debian.

I built GNUK 2.1 with arm-none-eabi-gcc version 12.2.1 20221205 (15:12.2.rel1-1) and picolibc-arm-none-eabi version 1.8-1. These packages are from the latest Debian 12 official apt software source. But I still get "Card Error" on the token.

Could you tell me the version of your toolchains?
