This was a bug in the AOS implementation of SPI which I think was still using a t30 style "slink" driver on t114. I don't know all the details but I would guess miniloader assumes you're about to write to the boot device so it applies the boot device timing parameters in the BCT to make sure it's running at greater than the bootROM failsafe clocks. -Allen -- nvpublic -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
