Hello
Im using SLG46826V on the dev board. I get this error whenever I connect an input from an ardiuno onto one of the test points. What is causing this issue? I have included a picture of the error and my two inputs are on TP2 and TP4

Hi, pls post complete schematic for analysis
Didnt think to ask this in the original post, will using a 3.3V input be casuing this error, while the greenPAK design is using a 5V rail?
You can build voltage translator inside greenpack for each Arduino input
Im still receiving the issue with 5V input, heres my schematic
Hi Sean,
this error caused board's external connections during socket test. You can turn-off (disconnect) buffered expander connector in debug tool before starting emulation and then turn them on. Do not use test points on the devboard for any external connections except measurment tools. It doesn't depend on VDD rail or design configuration. Please let me know if you have any questions.
Thanks for the reply PavloZ,
So i cannot connect inputs into any test points? How am I supposed to do testing on my chip then?
Hi Sean,
yes, test points are dedicated only for test equipment (scope, volmeter). Supplying voltage, shorting or connectin load can cause devboard damadge. There are expansion connector on the devboard. It has buffered IOs whith protection and on/off function. Please use that connector to test any of your circuit.
Thanks.
Please use expansion connector
