DA14585 16M flash烧录问题

Dialog 好，

我们由于项目需要用flash到16米,但在整个擦除中发现以下问题:

1.SmartSnippetsToolbox.exe等待超过10秒超时了。
2.经查看spi flash规格书，
规格书上写明 spi flash 整个擦除需要15秒才能结束。
现在是SmartSnippetsToolbox.exe只有10秒的等待时间，而spi flash整个擦除时间是15秒，

请帮忙解决，谢谢！！！！！

以下是相应的log
SmartSnippetsToolbox.exe -type spi -chip DA14585-00 -com_port 16 -cmd erase -max 2097152
