TPLD-PROGRAM: the evb damaged?

Chen Alex1

Part Number: TPLD-PROGRAM

Tool/software:

Hi Sir

I've been using the EVM to tune these past few days, and originally it was working fine. But then I got the following message.

I replaced the IC with a new one, and the results are still the same. Could the EVM board be damaged?

thanks

Hi Chen,

Could you share a picture of the EVM the TPLD-PROGRAM is connected with? Also, please verify the correct device is in the socket and is oriented correctly.

It looks like you have the jumper on DEBOUNCE ON mode on the GPI button input. That needs to be removed or in the DEBOUNCE OFF position, as per the EVM user's guide.

Hi Chen,

I'm not sure what the issue is. Could you give me more details as to what you expect to happen and what is actually happening?

HI lan

When ON2 Press down, the out pin(test) will pull high after 2S

I can't reliably debug the system without a clear description of the expected behavior and actual behavior.

I made some slight changes to get what I believe is the expected output behavior. Please confirm.

hi sir

I tested the On_off_v01_IG.syscfg file but it didn't resolve the issue. LED5(Pin 6) only turns on once every 2 seconds.

My requirement is that after pressing and holding the SW1 button for 2 seconds, LED5(Pin 6) should remain at a constant high level. Please help confirm this. Thx

Hi Chen,

To continue debugging, please provide a detailed description of the desired outputs of T2 and TEST, and a schematic showing the input connections. I cannot keep debugging with incomplete information.

Here is a version where the output TEST goes high after 2 seconds of high input on ON2.
