Can I connect a SSD drive to DRA821U2-Q1 for Linux OS installation with PCIe one Lane?

Thanks

Hi Max,

We do not have support for booting Linux off of PCIe currently in our SDK.

Hi Takuma,

I did not ask for booting up Linux from SSD, our bootstrap will be system boot up from OSPI NOR Flash, and Linux is installed on SSD.

it can run/load from it.

is that possible?

Thanks

Hi Max,

We currently do not have support for PCIe in U-Boot, so loading Linux through PCIe is not supported.

do you have a plan to add this support to U-boot in the near future?

Thanks

Does it support loading Linux from eMMC?

Thanks

Yes, there are plans/internal discussions, but not in the near future.

eMMC is supported in U-boot, so yes, it should be able to load Linux. There are instructions for booting to U-boot here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j7200/09_02_00_04/exports/docs/linux/Foundational_Components/U-Boot/UG-Memory.html. Section 3.1.1.5.4. Booting Linux from SD card or eMMC has some hints for how to boot Linux kernel.
