Title: TEBF0818 CPLD Access not working
Post by: ffloresg on March 11, 2026, 10:20:28 AM
Hello,

I am working with TE0808 on dev board TEBF0818.

I am trying to access and program the Lattice CPLDs on the TEBF0818 development board. I followed steps 1 to 6 in the CPLD Access section of the following guide: https://wiki.trenz-electronic.de/display/PD/TEBF0818+CPLD+Firmware

However, the Diamond Programmer did not found any device and created a default blank project.

Do you have any idea what might be causing this issue or how it could be resolved?

Thanks in advance.

Best regards,
Fernando

Hello Fernando,

please ensure that the DIP switch S4.3 is set to "ON"; if it is set to "OFF", this is exactly the behaviour you are experiencing.



Best regards,

Manuela

in your screenshot the Lattice programmer did show: FTUSB1 it should however be FTUSB0 !
