Hello,

It looks like you have it programmed correctly in the .gg file, check your connections to the SN74HC164 to make sure they are correct, you can review the EVM schematic to check the connections: https://www.ti.com/lit/ug/sluu904a/sluu904a.pdf?ts=1597156007785&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FBQ34Z100-G1

Yes, It is connected according to EVM reference, but the LED can't display according to RSOC.

Hello,

I would double check with the SN74HC164 datasheet and the EVM guide for the connections again, I uploaded your .gg file to a EVM and was able to get 4 LED's to light up, it is not the .gg configuration, it must be hardware.

Sincerely,
