NE40E of one site is problematic. In order to locate the problem, it need collect problem inforamtion. While checking the information, CF card has no record.
There is no log information on CF card. It need configure external CF card and then it can record the log.
NE40E can configure two CF cards. One is built-in and fixed on MPU. The card is to store program and configure data. Another is external and on NE40E. The card is to record log. NE40E does not configure external CF card, so there is no log after the problem occurs.
It is suggested that NE40 configures external CF card in the deployment.
