MSP430FR2311: 量产发现存在较大比例的烧录失败，SBW模式烧录失败，BSL模式无响应

Part Number: MSP430FR2311
Other Parts Discussed in Thread: MSP-GANG

上一批量产4800片，发现约300片不良，本批量产5600片，也出现大量不良。

具体现象为：

1.使用MSP-GANG一次性烧录8台，存在很大概率无法烧录

2.在最小系统板上验证良好的芯片，可以正常SBW和BSL模式烧录

3.拆下不能烧录的芯片焊到最小系统板上，SBW无法烧录，BSL模式下TX引脚无信号输出

以下是正常芯片BSL烧录（本次BSL烧录波形由FET430烧录，采用pulseView记录波形）

以下是不能烧录的芯片的波形（方法同上）

无法烧录的芯片，在FET430发送数据后，TXD引脚（10脚P1.7）上无信号输出

此产品已累计经量产5万+，之前一直良好，是否芯片存在不良？或者有某种bug？这样修板很麻烦，费钱又费力，请尽快提供支持。

BSL波特率采用默认的9600.失败的芯片日志如下：
