[FAQ] TDA4VM: How to boot from QSPI?

Part Number: TDA4VM

The default SDK supports booting from OSPI(OSPI0). How can we boot from QSPI aka OSPI1. What are the changes needed
in the u-boot?

  • Yes booting from QSPI is supported.

    1) By default U-Boot/SPL are configured to boot from OSPI(OSPI0). Hence we need do the following change in the U-Boot directory(This step is NOT needed for 8.5 SDK as latest SDK the dynamic detection of OSPI/QSPI is supported so NO need of the below patch jump to step 2):

    Once the newly built binaries are copied to boot partition of SD card. Boot to u-boot prompt using SD Boot:

    2) Dip switch settings:

    SW8: 10000010
    SW9: 00000000

    Boot to U-Boot prompt:

    sf probe 1:0 /* this is for QSPI */
    fatload mmc 1 ${loadaddr} tiboot3.bin; sf update $loadaddr 0x0 $filesize;
    fatload mmc 1 ${loadaddr} tispl.bin; sf update $loadaddr 0x80000 $filesize;

    fatload mmc 1 ${loadaddr} sysfw.itb; sf update $loadaddr 0x6C0000 $filesize

    3) Once QSPI is flashed please switch off the board and change the dip switch settings as below:

    SW8: 00000000
    SW9: 00100000

    Turn on the board. You can observe the below traces booting from SPI:
