MM9Z1I638 programmer issue

[gumu]

Dear Sir,

The project was originally using MM9Z1J638BM2EP 128kb flash, and now it has been changed to MM9Z1I638BM2EP 96kb. So I created a new MM9Z1I638 project but found that it cannot be programmed and occour a CRC error. I would like to ask what could be the general problem causing this. Thank you.

Hello @gumu,

Can you create a new empty project for the I638 part?

Try loading it without any custom code.

If this does not work, please contact PE Micro.

Thank you,

BR, Daniel

Yes, it's a new project.
