TUSB1046EVM: Connection to TUSB1046EVM Board with Aardvark I2C/SPI Programmer

user6294374

Part Number: TUSB1046EVM

Hi,

I would like to connect to the TUSB1046EVM with TPS6598x Host Interface Tools using the Aardvark I2C/SPI Programmer.

The TUSB1046EVM board is powered with USB-A to USB-B Cable from PC.

The following picture show the exception I encountered. Any idea to fix this?

Thanks,

Shu-He

Hi Shu-He,

Please make sure that TUSB146 I2C_EN is in the correct state (high or 1). Which pair of resistors are populated on your board, R67/68 or R69/70?

Hi Malik,

All four resistors are populated on the board.

And yes the I2C_EN is in the correct state as well (3.3V).

Thanks,

Shu-He

Hi Shu-He,

Sorry for the delay here. Are you still experiencing issues with I2C? If so I recommend shorting R67/68 to pin 3 & 4 of SW1 with some small wire.
