1. Meaning of the Error
"DEVICE ERR 01" is an error that occurs when there is an abnormal response from the target microcomputer during erasure execution.
If programming has not been successful even once (100% error rate), please first check the following points, including whether the programmer is set up correctly:
- Make sure that the correct definition program and Micom Pack are used for the target microcomputer.
- Check the manuals for the definition program and Micom Pack to ensure that the parameter settings are correct according to the conditions of your target board.
- Check the "Typical connection example" described in the manual of the Micom Pack to ensure that it is correctly connected to the target.
2. Main Error Factors and Remedies
-
The correct Micom Pack suitable for the target microcomputer is not used.
Example: If a Micom Pack for a product with a different flash capacity is used, an error response will be returned from the microcomputer when attempting to erase by specifying an address where the flash memory does not exist. -
The watchdog timer operated during erasure, causing the microcomputer to be reset and the erasure process to be interrupted.
-> For specific countermeasures when the watchdog timer is operating, please refer to the FAQ at the link below.

The ROM Block Configuration has been changed to an incorrect setting.
-> Load the parameter file provided in the Micom Pack and restore the ROM Block Configuration setting to its default value.-
Basically, customers should not change the ROM Block Configuration setting other than Block Size = 1 (setting to skip the execution of the device function). For details on the ROM Block Configuration settings, please refer to the FAQ at the link below.

-
The security (protection) function of the microcomputer is enabled, and erasure cannot be performed.
-> As the security (protection) function of the microcomputer varies depending on the device specifications, please refer to the relevant section in the manual of the definition program you are using.
