[TDA4 J721E SDK7.2] SPI module is loaded in "ko" mode, causing kernel running errors.

Hi There,

We change the spi kernel modules install strategy from buildin mode to ko mode.

Here are the kernel configuration changes we made in the file of tisdk_j7-evm_defconfig: 

CONFIG_MTD_SPI_NOR=y and CONFIG_SPI_CADENCE_QUADSPI=y,

After above modify, there are some errors caused on linux kernel side.

Error Scenario One: dmesg | grep spi

Why did the above errors occur after we modified the loading mode of SPI module( spi-nor.ko and spi-cadence-quadspi.ko),

please help to analyze the the differences between "buildin" mode and "ko" mode  in TDA4 platform.

    Hi,

    Linux expects boot media to be built in & not loadable. Can you try the below patch:

    https://e2e.ti.com/cfs-file/__key/communityserver-discussions-components-files/791/tiL5.10_2D00_P_2D00_spi_2D00_cadence_2D00_quadspi_2D00_Handle_2D00_spi_5F00_unregister_5F00_master_2D00_in_2D00_remove.patch

    The above Patch is on the latest 8.2 SDK. Please port it back to 7.2 SDK.

    Best Regards,
    Keerthy

    CONFIG_MTD_SPI_NOR=y and CONFIG_SPI_CADENCE_QUADSPI=y,

    These were made =m instead =y right? Are you not observing the above 3 error scenarios when the SPI is builtin?

    We now use =y instead of =m.

    Yes, these 3 error scenarios did not occur when the SPI is buildin.

    Hi,

    Since this is 7.2 based. I am doing the setup. I will get back to you by tomorrow.

    Hi He Li,

    I have now tried the below: 

    CONFIG_MTD_SPI_NOR=m and CONFIG_SPI_CADENCE_QUADSPI=m

    Attached are the logs from my EVM: ospi_module_logs.txt

    I do NOT see the above issue.

    I do not observe issue 3 as well.

    SO I do not see issues with changing CONFIG_MTD_SPI_NOR=m and CONFIG_SPI_CADENCE_QUADSPI=m.

    The probability of recurrence increases if you enable PHY and DMA in MCU domain.

    Moreover, Our Linux OS has enabled the phy-mode and SPI flash Pattern function in device tree,

    Can you describe this code change? I want to be on the same page as you are.

    He Li said:

    I will flash the SPI calibration pattern & check. Please provide the code changes you have w.r.t to enabling PHY and DMA in MCU domain.
    I want to reproduce the issue.

    Hi,

    Can you please check if SBL_ospiLeaveConfigSPI API is executed in SBL, at the end? If you are already executing this API at the end of SBL, can you please try adding "ospi_cfg.dmaEnable = false;" just to make DMA is also disabled in OSPI config?

    Hi，

        I enable SBL_ospiLeaveConfigSPI  function in SBL，and adding "ospi_cfg.dmaEnable = false;" in this function, the problem still exist . Can you repeat this problem at your EVM board？

    Hi,

    So you are using the SBL to boot to Linux. I was using the SPL to Boot to Linux. Basically you have changes on top of SDK on SBL side & you boot to Linux.
    Thanks for the patch. I will need to some time to setup 7.2 PSDK RTOS environment & try this.

        Our boot sequence is SBL->mcu RTOS app->uboot->linux. I modify the code in sbl_ospi.c file to test the case. To enable “SBL_ospiLeaveConfigSPI();“ function，i changed the code as blew。

    Since you have U-Boot in the boot path. Above patch pointed by Brijesh should help reset the flash. Could you please try that?

    You Do not have SPL in your boot path. SBL is being used for SPL but U-Boot is in your boot path after ATF. See the above sequence that you have quoted. So this patch will definitely have an effect. Please let us know.

    Hi Keerthy, 

    we now have not uboot path after atf, just use SBL->mcu app -> linux, we already removed the uboot-spl and uboot path during the booting process.

    Please note this. thanks.

    Hi,

    So it is SBL(MCU R5) --> MCU APP(MCU R5) --> A72 (ATF) --> A72(Linux)

    Can you please highlight why the OSPI needs to be a module? As it is the boot media we do not try that as a module.
    Also do you remove the module & then insert back or you see the errors even without removing the module?

    Hi He Li,

    Also is the issue easily reproducible or happens once in multiple runs?

    Dear Li,

         Just for a double-check of this case's background:

         At the beginning, we hope to reduce the boot time so that we open PHY mode of OSPI Flash. It works fine, however when running the whole system A72 and MCU will compete for the control of OSPI FLASH.

         As a result, you try to change OSPI driver to .ko for easy insmod and rmmod right?

      yes
    2.In the Linux side make OSPI as a module.
      yes
    3.Flash SBL to OSPI & also the combined app Image to OSPI & Boot from OSPI.
      yes
    4.The file system should be in eMMC or SD?
      in emmc
    5.Also what other remote runs apart from MCU_R5F, M3 & A72?
      dsp

    6.Also is the issue easily reproducible or happens once in multiple runs?
        easily reproducible

    We want to verify the ospi flash when mcu runs,also ,we need to write the flash when linux runs.So there is a need to switch ospi flash control between MCU and linux,thats why we need to make ospi driver as a kernel module

    Hi,

    The patch you had attached did not apply directly. I got a patch from our team internally. I have compiled the SBL changes now. I will test on the evm by Monday and get back with my findings. I checked with our internal experts that Dynamic sharing of ospi between cores is never tried or tested.

    In sbl and mcu app（autosar），MCU had done the close operation after ospi flash is used up。The problem still exits。The code list blew。Is the close operation correct？ Or still need do a reset ospi flash operation？

    Hi Jianye,

    I discussed with our OSPI expert. When handling the control to Linux the prior software has to release 1S mode.

    The SPL flow is now having the fix:

    TI__Guru**** 162380 points 
    On probe, the SPI NOR core will put a flash in 8D mode if it
supports it. But Linux as of now expects to get the flash in
1S mode. Handing the flash to Linux in Octal DTR mode means
the kernel will fail to detect the flash.

This commit adds an option to soft reset the flash after
spl_spi_load_image() so that the flash can be reset to 1S mode
and subsequent spi-nor probe in Linux does not fail, since
spl_spi_load_image() performs spi_flash_probe() the remove is
added after completion loading images in spi_flash_probe() itself.

    Hi,

    The case with reset is failing with the calibration pattern not found error.


    [ 4.450294] cadence-qspi 47040000.spi: Failed to find pattern at final calibration point
    [ 4.450296] cadence-qspi 47040000.spi: PHY calibration failed: -22

    Is the Phy calibration pattern flashed at the right address?

    Also after that can you rmmod the spi_cadence_quadspi & then modprobe so that it will effectively act as a resetting the controller and flash, so If the phy calibration passes the second time then we can suspect that the SBL did not leave the controller in proper state as the kernel expects.

    Best Regards,
    Keerthy
