My older dspproj checks OK, but my newer one, larger and with hierarchy blocks, reports a communication failure. It does not seems to be hardware related since it does it both on my production pcb and the development system: USBi and 1701 mini. The EEPROM is a 64K and the program is much smaller than that. Changing the EEPROM size specified in the dialog boxes does not seem to matter anyway; I can use 256K and it still works when it works.Any ideas anyone? Thanks in advance.
