Hi All,
I have used LCMXO640C lattice CPLD in my board. By mistake I have driven GSRN pin to low in my code and unknowingly I have programmed that code to CPLD using Diamond programmer. Now, I tried to program back with new code, where GSRN pin is corrected and when I try to program, I am receiving some error messages as below:
Device#1 LCMXO640C: Failed to verify the ID
(Expected: 0x01281043 Read: 0x00000000).
Check configuration setup: Unsuccessful.
Error: Programming failed.
I tried to erase existing CPLD and When I try to scan CPLD device, following is the error and so not able to erase also:
Scanning USB Port EzUSB-0...
Error: Scan Failed - Creating Blank Programmer Project.
I have no idea how to recover my CPLD back. Erasing current program will help me a lot. How to erase CPLD without a programmer?
If not, please give me some solution. I am very much in need. Please help me.
Thanks in advance.
