Hi,
I am trying to validate the PCIe interface j7200 EVM board , but its not working with pre-build binaries received through SDK from TI.
Please suggest what changes need to be done w.r.t configure/device tree changes to bring it to working condition.
Also i try to find the respective driver details in Documents folder for TCA9543APWR as per information given in the TI user guide (attached snapshot for reference) but didn't find any .
Regards
Praveen
Hi Praveen,
Could you share with me which Processor SDK Linux version is being used, and also share the output from dmesg? For example, piping the output from dmesg to a text file and sharing it will be great "dmesg > dmesg_output.txt".
There should not be any need to change device tree when using the TI EVM as a RC device (aka, if the goal is to connect EP devices like a NVMe SSD to TI EVM). With current information, some things that could be causing issues are the following:
If the screenshots are too small to see, please reference the EVM user guide here: https://www.ti.com/lit/ug/spruiw7a/spruiw7a.pdf. The relevant sections are 4.11 PCIe Interface, and 3.4 EVM DIP Switches section.
If we can verify hardware configuration is correct, then we can go through the dmesg logs to see if we can spot any issues software-wise.
Regards,
Takuma
Hi Takuma,
Below are the h/w configuration details :

Hi Praveen,
That is very strange... software-wise, it looks like PCIe controller is getting initialized based on these logs:

So as of now, it seems issue may be hardware related. To understand what is happening, could you do the following:

Takuma
Hi Takuma,
you can just google the "intel gigabit ct desktop adapter" for reference pci interface ethernet card.
even i don't have any other pci interface card to try out.
Attached snapshot also
Hi Praveen,
I see some concerning reviews on the product page for that card. For example:
Looking through the datasheet and at the form factor, it does seem like a PCI-Express card, but I would recommend you obtain a different cheap PCIe interface card to test if the issue is with the card or the TI board/SDK.
On my end, I have tested with a PCIe WiFi card (Intel 9260 with adapters to fit the PCIe slot) with 8.6 SDK on J7200 and the card gets detected fine.
Regards,
Takuma
Hi Takuma,
Okay, let me arrange different PCIe card to try out this.
In mean time , can you please share the details of changes required in dtb also w.r.t driver for this pcie interface, i just curious to have a look once. even if you share reference section in doc also fine , i will go through it.
Regards
Praveen
Hi Praveen,
The default TI dts should have PCIe enabled already. You can also confirm here: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/tree/arch/arm64/boot/dts/ti/k3-j7200-common-proc-board.dts?h=ti-linux-5.10.y#n418.
Documentation can be found here: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j7200/09_01_00_07/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/PCIe/PCIe_Root_Complex.html.
As a warning, due to holiday I will be out until Tuesday next week, so my responses will be delayed.
Regards,
Takuma
Hi Takuma,
Thanks for your inputs, let me go through these links and will come back to you if i have any further queries.
Regards
Praveen
Hi Praveen,
Sounds good, and of course, let us know if there are further questions or any extra information you may find.
Regards,
Takuma
Hello Praveen,
The driver in Linux corresponding to the Intel PCIe Ethernet Card you are using (Intel® 82574L Gigabit Ethernet Controller) is:
drivers/net/ethernet/intel/e1000e/82571.c
Please ensure that the following configs are enabled in the Linux's .config that you are using to build Linux:
CONFIG_NET_VENDOR_INTEL=y
CONFIG_E1000E=y
Regards,
Siddharth.
