Hi Aya,

Thanks for that, I've implemented the recommendations.

1 thing that would be good to confirm is the correct software image for the flash?

thanks

Hi Ciaran,

Have you generated a project using the following tool: https://www.ti.com/tool/TPS6598X-CONFIG ? I do not see any files attached here.

Hi Aya,

No I was not aware of the tool and planned to used the same file as the EVM. Can I do that?

Looking at this guide it calls for "USB-C-PD-DUO-EVM" but it seems obsolete and not available to buy anywhere?

Rgds,

Hi Ciaran,

You will need to use the GUI tool to configure the device's registers to align with your design requirements. The tool can then generate a binary file which is then used for flashing.

I suggest watching the GUI tutorial videos on how to get started. Also refer to the GUI user guide here.

Please let me know if you have additional questions/concerns.

Best Regards,

Hi Aya,

Having looked at the videos it sound like I can program the SPI flash in circuit using some USB to SPI adapter. Can you recommend one that works with the GUI please? I noticed "FTDI" was selected in the demo video but I'd prefer to use a known good cable adapter.

thanks

Hi Ciaran,

We have used the Total Phase Aardvark adapter during internal development. This would work with the GUI as well.
