加密芯片自检无法通过

[bwc2019]

问题描述

调用mi_scheduler_start(SYS_MSC_SELF_TEST)进行加密IC自检出现以下异常，请帮忙分析一下原因：
0> [W] secure auth: START 0x000000A2
0>
0> [I] secure auth: MSC self test:........0
0> [I] MSC: Start MSC cmd 0x28 @ schd_ticks 5
0> [I] MSC: Waiting... @ schd_ticks 5
0> [I] MSC: Ready now. @ schd_ticks 5
0> [E] MSC: MSC data len error. 255,6
0> [I] MSC: Finish MSC cmd 0x28 @ schd_ticks 5

0> [I] secure auth: MSC self test:0,0,0........2
0> [I] MSC: Start MSC cmd 0x22 @ schd_ticks 5
0> [I] MSC: Waiting... @ schd_ticks 5
0> [I] MSC: Ready now. @ schd_ticks 5
0> [E] MSC: MSC data len error. 255,0
0> [I] MSC: Finish MSC cmd 0x22 @ schd_ticks 5

0> [I] secure auth: MSC self test:........3
0> [I] secure auth: MSC self test: FAIL
0> [I] : USER CUSTOM CALLBACK RECV EVT ID 16
0> [W] secure auth: monitor power off

报错的时候数据长度不一致：
data_len = 255
p_cb->data_len = 6

如何复现

调用mi_scheduler_start(SYS_MSC_SELF_TEST)

期望结果

自检成功

环境描述

蓝牙芯片：nrf51802
加密芯片：mja1

其他补充

在mi_config.h文件中已做了如下配置：
#ifndef HAVE_MSC
#define HAVE_MSC 2
#endif
