TBSIMP_E_TPM_INCOMPATIBLE
The TBS implementation and TPM do not match
TBSIMP_E_TPM_INCOMPATIBLE (0x8029021A) means the implementation cannot operate with the detected TPM generation/capabilities in the requested mode. This is broader than one unsupported ordinal.
Evidence to capture
Record detected TPM version/capabilities, firmware, TBS implementation/OS version, context parameters, and whether platform firmware changed TPM mode.
Focused correction
Use the Windows/TBS path intended for the installed TPM generation and supported platform configuration. Avoid converting command bytes until the stack/version mismatch is resolved.
