Hi V,

Thanks for sharing your schematic. We can review and get back to you with feedback.

Hi V,

Please find the schematic checklist attached with my comments included.

I've configured the "Strap Tool" section for the configuration you shared.

Note the reference schematic you shared has a different strapping configuration.
