HI,
I need some advice, I was programming a Lattice LPX2-8E-5TQFP144, with an updated FPGA code.
But I got the programming pins on the JEDEC interface the wrong way around, the correct pin connection should be:
Pin Function
1. Vcc
2. TDO
3. TDI
4. TMS
5. GND
6. TCK
Accidently, I connected the JEDEC interface as:
Pin Function
1. TCK
2. GND
3. TMS
4. TDI
5. TDO
6. Vcc
The programming failed.
After seeing my stupid mistake, I reversed the connector, but Chip ID could not be found.
Is the LPX2 damaged and requires replacing?
