DAC37J84EVM: DAC37J84EVM : can't read register of DAC37J84EVM.

Hello BH,

There appears to be some DAC37J84 EVM where the CPLD was not programmed properly. We had offered an exchange to the EVM to resolve the issue. You may private message me your contact information, shipment address, and phone number so I can do so if needed.

Before we begin this process, we need to confirm if you have gone through all the steps in the EVM user's guide to program the GUI properly. Please confirm if you still cannot read back the SPI register after programming through the GUI.

You mentioned you can't connect your DAC37J84EVM. Please advise if the issue is due to USB connection or a SPI readback error. 

I was testing with DAC3xJ8X GUI v1.2. It is  a SPI readback error not USB Connection.

I probed SPI signals of the J24, J25 Connectors with scope.

I think SPI Write Operation with USB of EVM board operated well except Read Operation.

BH,

I had private messaged you. Please send me your contact information and telephone number. We can send you a replacement.

BH,

The EVM is on its way.

Regards,

Jim
