DRA821U: DRA821U J7200 EVM cannot scan PCIe card on PCIe slot

Rich Chen
Expert 4260 points
Part Number: DRA821U


Tool/software:

Dear champ, 

Customer is using J7200 EVM and try to verify PCI function by using PCIe cards on J7200 EVM PCIe slot. 

SDK 9.0 and SDK 10.0 are both tried following the instructions below 

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

https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j7200/10_01_08_01/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/PCIe/PCIe_Root_Complex.html

Rebuild Linux Kernel with the flags require and boot up EVM with PCIe ethernet card installed on both PCIe slots. 

Linux Driver Configuration

The following config options have to be enabled in order to configure the PCI controller to be used in Root Complex mode.

CONFIG_SOCIONEXT_SYNQUACER_PREITS=y
CONFIG_PCI=y
CONFIG_PCI_MSI=y
CONFIG_PCI_J721E=y
CONFIG_PCIE_CADENCE=y
CONFIG_PCIE_CADENCE_HOST=y

However, lspci cannot get any device ID but only rc pid vid. 

Is there any addition modification is required? 
How can we verify this with SDK 10.1 pre-build image? A instruction will be helpful. 
 
 
BR, Rich

    Hi Rich,

    I just tried with Processor SDK 10.1 for J7200, and I flashed the prebuilt default image to the micro SD card. I was able to detect a NVMe SSD card on the J8 connector.

    Specifically, I used the instruction "1.1.4.5. Create SD Card with Default Images using script" in the SDK documentation to create the bootable SD card:

    https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-j7200/10_01_08_01/exports/docs/linux/Overview/Processor_SDK_Linux_create_SD_card.html#create-sd-card-with-default-images-using-script

    And I used a Kingston NV2 TC2200 SSD card with an adapter from M.2 to PCIe connector.

    Attached below are my logs:

    It might be that the DIP switch that controls PORz signal behavior is set wrong. Can they check if switch 3.6 is OFF position? Mine is set like below:

    Takuma, 

    Thanks for the try to confirm this and provide log for comparing.

    On the SW3 setting, we checked the setting for EP mode and it shows SW3.5 and SW3.6 should be set to "1" so customer tried both "00" and "11" but not seeing difference. 

    For End Point mode, PCIE_1L_MODE_SEL (switch 5) and PCIE_2L_MODE_SEL (switch 6) in sw3 should be set to ‘1’.

    We will compare your setups and check what could be different or missing.

    Hi Rich,

    Understood. If a PCIe EP device is connected to the SoC acting as a RC (for example, plugging in a SSD card) then please make sure dip switches are in RC mode. 

    Regards,

    Takuma, 

    I have confirmed the problem coming from the PCIe card generation support. 

    I use a GEN5 NVMe SSD also M.2 type module with PCIe adaptor and I have no problem seeing the device with pre-build image. 

    GEN 5 can backward compatible with GEN2 and GEN3 depend on the PCIe RC support specification during negotiating. 

    Customer uses GEN 1 Ethernet card and GEN1 seems not support in our driver so lspci will not show GEN1 device on list.

    I asked customer to find GEN 2 and GEN 3 PCIe cards and these cards can be scanned without problem. 

    This means our current RC doesn't support GEN1 in our support list or there is bug on it since negotiation will be happen in 2.5G clock speed. 

    Please check this and extend support for GEN 1 cards. 

    BR, Rich

    Hi Rich,

    Try below patch out:

    https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/0001_2D00_Force_2D00_max_2D00_speed_2D00_to_2D00_PCIe_2D00_gen_2D00_1_2D00_speed_2D00_for_2D00_PCIe_2D00_control.patch

    What the above patch does is force GEN1 speed for J7200. Below are the lspci -vvv logs that shows a PCIe NVMe SSD card that is capable of GEN4 speeds linking down to GEN1 speed.

root@j7200-evm:~#

    As for some background of the experiment, I do not have a card that only goes up to GEN1 speeds, so as an alternative approach I tried to force the PCIe controller to link up to GEN1 speed. 

    I found the driver always advertises the max speed to be GEN2 or above. This should not be an issue, since it is only the max speed that is hardcoded and PCIe should be able to negotiate during link training by matching the lesser capability. But, I was not able to force GEN1 speeds due to this hardcoding. What the patch does is to remove the hardcoding for always advertising GEN2 or above in case the negotiation was somehow failing.

    Regards,
