HPA109 revb evm with EV2300

burak balkuv

When I first launch the TPS2384EVM program it does state " USB to I2C interface Found", however there is an error code 772 displayed.

I can't talk to the device, cant read cant write.

LED D7 is on.

Is there any info on error codes, jumper settings for I2C address for the EV2300 to work with HPA109.

I have installed

Have the EVM jumpers been configured per paragraph 4.5 of the EVM user guide?

I can get the 772 error code if I remove the shunt on J6 (V3.3 on the PCB). Otherwise the EVM works fine. Can you measure the DC voltage at TP3.3 and V3.3 with the J6 shunt installed? The voltage should be 3.3V. If that is fine, then you may have a defective EVM and I can send you the one I have.
