全时接收TPM_RC_BAD_TAG

Question

试图使用婴儿slb9670与狼to。当将lib移植到自定义spi函数和os时，接收0x01e(12月30日)，这意味着TPM_RC_BAD_TAG。如果我已经收到了上限，我的Spi连接是否正确？(同样的代码在带有STM32f7实现的STM32f7板上运行良好)谢谢

rc = TPM2_Init(&tpm2Ctx, TPM2_IoCb, userCtx);
if (rc != 0) 
{
    tst_printf("\r\nTPM init failed! rc = %i;", rc);
    break;
}
else
{
    tst_printf("\r\nTPM init success!");
    tst_printf("\r\nTPM2: Caps 0x%08x, Did 0x%04x, Vid 0x%04x, Rid 0x%2x \n",
    tpm2Ctx.caps,
    tpm2Ctx.did_vid >> 16,
    tpm2Ctx.did_vid & 0xFFFF,
    tpm2Ctx.rid);
}
/* define the default session auth */

XMEMSET(tpm_session, 0, sizeof(tpm_session));
tpm_session[0].sessionHandle = TPM_RS_PW;
TPM2_SetSessionAuth(tpm_session);
if (rc != TPM_RC_SUCCESS &&
    rc != TPM_RC_INITIALIZE /* TPM_RC_INITIALIZE = Already started */ ) {
    tst_printf("TPM2_SetSessionAuth failed 0x%x: %s\n", rc, TPM2_GetRCString(rc));
    break;
}

Startup_In startup;
XMEMSET(&startup, 0, sizeof(Startup_In));
startup.startupType = TPM_SU_STATE;
rc = TPM2_Startup(&startup);
if (rc != TPM_RC_SUCCESS &&
    rc != TPM_RC_INITIALIZE /* TPM_RC_INITIALIZE = Already started */ ) {
    tst_printf("TPM2_Startup failed %i: %s\n", rc, TPM2_GetRCString(rc));
    //break;
}

tst_printf("\r\nTPM2_Startup pass!\f");

输出：

TPM init success!
TPM2: Caps 0x30000697, Did 0x001b, Vid 0x15d1, Rid 0x10
TPM2_Startup failed 30: Unknown

编辑的

cmd在TPM2_TIS_SendCommand中的值：

80 01 00 00 00 0c 00 00 01 44 00 00             (working example)
00 00 00 00 00 0c 00 00 01 44 00 00             (my case)

必须由TPM_ST_NO_SESSIONS添加的80 01 -

错误是在准备包裹的功能上。我的IAR编译器版本不能处理16位值的__REV()。我用小宏来处理，现在一切都很好。
