Dear team,
I would like to ask about PCIe of i.MX7D SABRE board.
I found the following statement about PCIe use in your i.MX Linux Release Notes(IMXLXRN, Rev. L4.1.15_2.0.0-ga).
In Table-22;
Desc.: “Cannot probe up PCIe devices on Rev. C board.”
Workaround: “Hardware rework is required. Rework: Change C459&C458 caps to 0 ohm resistors.”
Does the above mean that PCIe on Rev.C i.MX 7Dual SABRE-SD board does not work without the rework of C459&C458?
And do you know that PCIe on the Rev.D board can surely work without any workaround?
Thanks,
Miyamoto
Hello,
Correct, "PCIe on Rev.C i.MX 7Dual SABRE-SD board does not work without the rework of C459&C458".
The Rev.D has no changes regarding C459 & C458 - so, the (PCIe) rework is needed for the Rev.D
Have a great day,
Yuri
