> > Whether eMMC or SSD in M/B will be locked down during SMT by BOM therefore could we take care of that for non-mounting one (either eMMC or SSD) we can fine-tune pins for N/C, PU or PD to avoid any leakage or interrupt storm? As a result, at least we can support 255?

> Dear Marco, sorry feedback to you later. I confirmed with our factory team and PM, Proto board just power on, BTW don't do factory flow. So I think SKU255 for Proto build that is fine.

1. Even for proto stage, the SKU ID 255 still needs to be ensure that board can be power on generally; otherwise everyone got this board needs to re-program SKU ID by servo console?

2. Considering to EVT, we still need to evaluate to boot up by 255.
