Question: I can't download the my firmware (the .rom file) onto my CY3650. When I download the file "test.rom", Why does the PC pop up a message saying "cmdDnldDnld_Click: DownLoad of test.rom ended before all valid characters were loaded into Program RAM. Stopped at Program RAM Address1"?
Answer: The cause for such error is usually a bad connection or wrong settings.
There are a couple settings you might want to check.
- Go to My Computer/Control Panel/Regional Settings and make sure this is set to English (United States).
- Is the board powered?
- Make sure you have connected the RS232.
- Set the Comm Port settings to:
Baud rate = 19200
Data Bits = 8
Parity = None
Stop Bits = 1
Flow Control = Xon/Xoff
My guess is that you have the Regional Settings not set to English, but if this is not the case, check the switches - S1 and S3 - and COM port settings.
