QCS8550的平台上qsee_sfs_open 打开和创建文件失败.
代码:
static int saveDataToSfs(uint8_t *fileid, uint32_t fileid_size,
    uint8_t *data, uint32_t data_size, int *count)
{
    int ret = ERROR_FAIL, fd = 0;
    uint32_t size = 0;
    ((void) fileid_size);;

    fd = qsee_sfs_open((const char*)fileid, O_CREAT | O_RDWR | O_APPEND);
    if (0 == fd) {
        EMSG("open fs fail %s", fileid);
        goto exit;
    }

    if (qsee_sfs_getSize(fd, &size)) {
        EMSG("get fs size fail");
        goto exit;
    }

    if (size == 0 && count != NULL) {
        *count += 1;
    }

    ret = qsee_sfs_write(fd, (char *)data, data_size);
    if (data_size != ret) {
        EMSG("write fs fail, data_size %d, write size %d", data_size, ret);
        goto exit;
    }
    ret = SUCCESS;

exit:
    if (fd && qsee_sfs_close(fd)) {
        EMSG("close fs fail");
    }

    return ret;
}

使用系统中带上的测试程序:
vendor/qcom/proprietary/securemsm/sampleclient/qseecom_sample_client.c
将CLIENT_CMD0_GET_VERSION的发送CMD实际改为CLIENT_CMD5_RUN_SFS_TEST

再执行 qseecom_sample_client v smplap64 0 1
结果如下:

最后的部分的咯个log可以看到, test pass了:

目前sfs可以跑通，你那边也可以尝试下.
