Part Number: TDA4VM

Hi,

OSPI boot with SDK 7.3 is functional but before getting to u-boot prompt we encounter a lot of error messages.

TISCI config ring fail (-19) ring_idx 6

TISCI config ring fail (-19) ring_idx 124

…

…

TISCI config ring fail (-19) ring_idx 6

TISCI config ring fail (-19) ring_idx 124

How to fix the above erros?

Best Regards,
Keerthy

    Hi,

    Post HSM Re-architecture i.e from SDK 7.1 onwards, all messages sent via Device manager to TIFS channel would need to use
    a non secure host ID in hdr->host. Therefore switch to using non secure host ID of MCU R50 in R5 SPL.

    Fix DMA/ring related error seen during OSPI boot on J721e/J7200 using the below patch:

Subject: [PATCH] firmware: ti-sci: Use non secure host ID
 for RM requests in R5 SPL

Post HSM Rearch, all messages sent via DM2TIFS channel would need to use
a non secure host ID in hdr->host. Therefore switch to using non secure
host ID of MCU R50 in R5 SPL.

Fix DMA/ring related error seen during OSPI boot on J721e/J7200.

    The above patch is applicable only to SDK 7.3.

    Steps to apply the above patch to u-boot and build:

    cd $SDK_DIR/board-support/u-boot-2020.01+gitAUTOINC+2781231a33-g2781231a33
git am 0001-firmware-ti-sci-Use-non-secure-host-ID-for-RM-reques.patch.txt
cd ../..
make u-boot
cp board-support/u-boot_build/a72/u-boot.img board-support/u-boot_build/a72/tispl.bin board-support/u-boot_build/r5/tiboot3.bin /media/$USER/boot


    Boot with SD card with the above images and we should see that the tisci errors go away.

    In case you are observing the below error:

    WARN: PHY calibration failed: -2
    That is totally unrelated to the tisci fix mentioned above & you need to flash the OSPI calibration pattern using the steps beow:

    Download the zipped flashing pattern binary here: 3835.nor_spi_patterns.zip

    Copy the unzipped nor_spi_patterns.bin file to boot partition of SD Card. Once you boot to u-boot prompt:

    For J721e

    sf probe
fatload mmc 1 $loadaddr nor_spi_patterns.bin
sf update $loadaddr 0x3fe0000 $filesize

    For J7200:

    sf probe
fatload mmc 1 $loadaddr nor_spi_patterns.bin
sf update $loadaddr 0x3fc0000 $filesize

    The above should burn the calibration pattern to the appropriate address. Reboot and you should see that phy calibration failed error is fixed.

    Best Regards,
    Keerthy

    hi

    WARN: PHY calibration failed: -2

    The above issue still exist when flash the OSPI calibration pattern file to  ospi flash. I use SPL guide.

    Hello Wang Liu,

    For j7200 the offset is different 0x3fc0000 for flashing the nor_spi_patters.bin.
