It seems that USBDM could support FXTH870911DT1, because there is FXTH87XX11 item in device selection. But when I try to program an S19 file, it says target is secured and mass erase is needed. And when I select EraseMass, it says program data not within target Flash Memory.
Chip detecting is successful. What should I do to program FXTH87 with USBDM?
USBDM version: 220.127.116.11
