使用PN5180读取mifare class 1k 验证失败：Authentication Failed

Question

使用PN5180读取mifare class 1k 验证失败：Authentication Failed!!!

使用nxp官网的库中的NfcrdlibEx4_MIFAREClassic这个demo ，UID是可以读出来的，但是就是认证失败：Authentication Failed!!!
demo中的代码如下：

     /* Check for MIFARE Classic */
            if (0x08 == (pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aSak & 0x08))
            {
                do
                {
                    /* Print UID */
                    DEBUG_PRINTF ("\nUID: ");
                    phApp_Print_Buff(pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aUid,
                            pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].bUidSize);

                    /* Print ATQA  and SAK */
                    DEBUG_PRINTF("\nATQA:");
                    phApp_Print_Buff(pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aAtqa, 2);
                    DEBUG_PRINTF ("\nSAK: 0x%x",pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aSak);

                    /* Print Product type */
                    DEBUG_PRINTF("\nProduct: MIFARE Classic \n");

                    bUidSize = pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].bUidSize;
                    memcpy(bUid, pDiscLoop->sTypeATargetInfo.aTypeA_I3P3[0].aUid, bUidSize);

                    /* Authenticate with the Key
                     * We can authenticate at any block of a sector and we will get the access to all blocks of the same sector
                     * For example authenticating at block 5, we will get the access to blocks 4, 5, 6 and 7.
                     */
                    /* Send authentication for block 6 */
                    status = phalMfc_Authenticate(psalMFC, 6, PHHAL_HW_MFC_KEYA, 1, 0, bUid, bUidSize);

                    /* Check for Status */
                    if ((status & PH_ERR_MASK) != PH_ERR_SUCCESS)
                    {
                        /* Print Error info */
                        DEBUG_PRINTF("\nAuthentication Failed!!!");
                        DEBUG_PRINTF("\nPlease correct the used key");
                        DEBUG_PRINTF("\nExecution aborted!!!\n");
                        break;
                    }

通过log可以看出，输入的信息是没有问题的：

Authentication Failed！
Please correct the used key
Execution aborted!

Please Remove the Card
麻烦帮忙看一下问题出在什么地方了,万分感谢！！

这是认证时候的校验问题，我的最新代码已经成功读写，开源代码见：https://gitee.com/jhuangBTT/HAL_STM32_PN5180_SPI_DEMO，能帮助到你的话我的CSDN点个关注，谢谢。
