TDA4VM: TDA4 peripheral identification

Massimo Toscanelli
Prodigy 80 points

Part Number: TDA4VM

Hello,

I want to test the SPI peripherals connected to the SoC in the j721e EVM using the Linux Kernel. From the user guide I read that there are 3 memories connected: MT35XU512ABA1G12-0SIT, S71KS512SC0BHV000, MT25QU512ABB8E12-0SIT.

Following the Linux documentation of the Linux SDK, I ran

$modprobe cadence-quadspi

$cat /proc/mtd

and I could see 8 MTD devices: 7 mapped on the OSPI and 1 on the SPI.

My problem is that I cannot understand exactly which memory they correspond to.

How can I understand so? And if not all 3 the flash devices are configured, how can I do it?

In the TI RTOS PDK instead, I found a sample code to test a master slave communication between MCU1_0 and MPU1_0 using the MCSPI.

Is there a way to do the same with the Linux Kernel? If yes, how?

I also tried to configure the Kernel following the Kernel User Guide (https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Foundational_Components_Kernel_Users_Guide.html)

make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_amNNNx-evm_defconfig

I found that there is no option mentioned for the J721E platform.

Could you please also tell me how this configuration can be done?

Thank you in advance.

    Hi Massimo,

    Could you please share the logs of cat /proc/mtd? Are you on 7.0 SDK?

    Hi Keerthy,

    Yes, I'm on 7.0 SDK.

    This is the log:

    dev:    size   erasesize  name
    mtd0: 00080000 00020000 "ospi.tiboot3"
    mtd1: 00200000 00020000 "ospi.tispl"
    mtd2: 00400000 00020000 "ospi.u-boot"
    mtd3: 00020000 00020000 "ospi.env"
    mtd4: 00020000 00020000 "ospi.env.backup"
    mtd5: 00100000 00020000 "ospi.sysfw"
    mtd6: 03800000 00020000 "ospi.rootfs"
    mtd7: 04000000 00010000 "47050000.spi.0"

    By the way, in these days I read better the documentation and I realized that OSPI and Hyper flash cannot be both connected at the same time.

    So, this is the log when the OSPI flash is active, but instead, switching to the Hyper flash I can just see the last "47050000.spi.0" device.

    Is it correspondent to the MT25QU512ABB8E12-0SIT device?

    How can I manage to "mount" the Hyper flash?

    Best regards,

    Massimo

    Hi Massimo,

    "47050000.spi.0" device corresponds to OSPI1 master device & that is connected to MT25QU512ABB8E12-0SIT flash.

    Details about hyperflash: https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Foundational_Components_U-Boot.html#hyperbus-and-hyperflash

    What exactly do you mean by mounting Hyper flash? You want to use it for rootfs? I want to understand your use case.

    Best Regards,
    Keerthy

    Hi Massimo,

    Also please provide the kernel version that you are using. If you can share the complete bootlog that would
    be even more helpful.

    Best Regards,

    Hi Keerthy,

    My aim is to test the SPI peripherals with the Linux kernel.

    Since we have these 3 memories connected to the OSPI, I thought that writing and reading from them could be the easiest way to test SPI.

    When I activate the MT35XU512ABA1G12-0SIT, I can see it as mtd partitions, as I shown you in the previous comment. Here you can see the boot log:

    Hi Massimo,

    On kernel 5.4 the hyperflash is disabled as there is an errata around that. So It is not enabled
    in 5.4 kernel. Hope this gives you the explanation for your observation.

    Keerthy

    Hi Keerthy,

    thank you so much for your explanation regarding the hyperflash.

    What about the IPC sample code that I mentioned at the beginning of the thread?

    Is there a way to allow master slave communication between MCU1_0 and MPU1_0 using the MCSPI?

    Best regards,

    Massimo

    Hi Massimo,

    Thanks for your patience. On Linux side we have master mode support but not Slave mode
    support is added in the SDK. I got a confirmation from the SPI expert as well that slave mode is
    not supported in Linux. Hope this answers all your questions. Please let me know if you need
    anything else on this subject.

    Hi Keerthy,

    Thank you for your response.

    About the MTD devices instead, they are configured in the Kernel to be used at certain frequencies, with or without DMA.

    I would like to test them changing their configuration and I tried to configure the Kernel following the Kernel User Guide (https://software-dl.ti.com/jacinto7/esd/processor-sdk-linux-jacinto7/latest/exports/docs/linux/Foundational_Components_Kernel_Users_Guide.html)

    When I reach this step I cannot go on because no option is mentioned for the J721E platform:

    make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- tisdk_amNNNx-evm_defconfig

    Could you please also tell me how this configuration can be done?

    Best regards

    Massimo

    Hi Massimo,

    Yes there is no mention of j7/tda4 part in that. I will request for documentation update.
    That said if you want to change config options you should be able to do that here:

    arch/arm64/configs/tisdk_j7-evm_defconfig

    this is the defconfig used for TDA4/J7. You can modify the configs for your need and just do 'make iinux'
    from the SDK folder installation and that should give you the new kernel Image.

    Best Regards,
    Keerthy
