UCD90240ZRB can't be switched to ROM mode

Other Parts Discussed in Thread: UCD90240

Hello,

We're designing programming solution, 3rd party programmer, for our customer. We're faced with issue when we can't switch the device to ROM mode using command D9h. Before issuing command D9h we can read firmware's DEVICE_ID value.

I can provide signals traces from communication. In this case I'll prefer communication via e-mails.

Thank you.

BR,
