I2C use by ULP and CPU

Hello,

I'm trying to use the same pins for I2C in ULP and CPU (active mode) but when I try to use it, nothing works. Is it possible to have both configured to use the same pins or should I use different ones?

I'm using SDA pin as the 33 and SCL as the 32. Also I tested both in separated programs and they worked, no when I put them together.

Regards,
Pascal.

If they work in separate programs they should work together, just not at the same time.

Ok, will then debug further to see what's going on. Thanks!
