DS250DF410EVM: DS250DF410EVM Sigcon GUI problem

DS250DF410EVM: Using a USB2ANY dongle to connect SigCon Architect instead of the onboard MSP430

Part Number: DS250DF410EVM
Other Parts Discussed in Thread: USB2ANY, DS250DF410

Tool/software:

Hello TI team,

I would like to connect to the DS250DF410EVM via a separate USB2ANY interface adapter and SigCon Architect so that the SPI lines of the adapter can be run to another device.  Then the USB2ANY can be used to configure the SPI device before opening SigCon Architect and configuring the retimer.

What jumper settings are needed to disable the MSP430 on-board the EVM?  Does the keyed 10-pin cable from the USB2ANY plug into the connector along the bottom edge of the EVM? I have the User Guide (SNLU203) but it only shows the default jumper settings and does not describe the jumpers functions. Is there anything else I need to consider such as the source of the 3.3V and pull-ups for the SMBus?

Our design will have an MSP430, I2C muxes, LMK clock chip(s) and more than 16 retimers on each board with only one USB connection.  We would like to be able to access the different components using USB2ANY and their associated software such as SigCon Architect.  It is my understanding that you provide the USB2ANY binary for the MSP430 and an App to flash but do not support it beyond that.  Getting a second interface to work through the same USB2ANY that the EVM is attached to is our first step in prototyping this design

Thanks Eric.

    Hi Eric,

    I'm looking into this and will get back to you with more feedback tomorrow.

    Best,

    Lucas

    Hi Eric,

    I just approved your access to DS250DF410 secure resources.  You will find EVM files (schematic, layout) on there, which I think will help answer many of your questions.

    No, this does not have I2C connections.

    I would recommend removing shunts from J24.  These connect MSP430 I2C to the DS250DF410 I2C.

    In order to connect a USB2ANY, I'd recommend connecting the USB2ANY SCL, SDA, and GND to J18.

    We have observed that external USB2ANY works fine with 2.5V pullups (populate J15 with shunts).  However, in the schematic, you'll see that R33/R64 would typically pull I2C to 3.3V.  You may want to add 3.3V pullups in your board design.

    Thanks,

    Drew

    Drew,

    Thank you for addressing all my questions. The schematic did indeed help us understand what jumper settings were needed and where best to patch in the external USB2ANY. We were able to successfully connect with SigCon Architect to configure the retimer. Next will be sending configuration data over SPI to an LMK attached to the same USB2ANY. I will post if we have issues with that.
