Hi,
Indeed, I have the same problem :
TBOOT: TXT.ERRORCODE: 0xc0041d01
TBOOT: AC module error : acm_type=0x1, progress=0x10, error=0x7
TBOOT: LCP2 error: minor error = 0x3f, index = 399
The related structure is in ./tboot/include/txt/errorcode.h :
80 union {
81 uint32_t tpm_err : 9; /* progress=0x0d,
error=1010 */
82 struct { /* progress=0x10 */
83 uint32_t lcp_minor : 6;
84 uint32_t lcp_index : 9;
85 };
86 }; /* sub-error */
87 uint32_t reserved : 5;
88 };
89 } acmod_error_t;
According to sinit_errors.txt, I think the lcp_index variable should be
3 bits instead of 9 :
Bit Description
----- -----------
24:16 LCP v2 minor error code, valid only for progress code 10h
24:22 Index (in LCP_POLICY_DATA::PolicyLists) of item
responsible for error
21:16 Minor error code (see progress code 10h below)
But with this correction I still have interpretation error :
TBOOT: TXT.ERRORCODE: 0xc0041d01
TBOOT: AC module error : acm_type=0x1, progress=0x10, error=0x7
TBOOT: LCP2 error: minor error = 0x30, index = 0
Yours,
Fred
