[FAQ] TDA4VH: OSPI FLASHING USING DFU cum DFU Issues

SDK 9.2 Issues:

• The tiboot3.bin has a size > 512 KB which causes issues.
  • Hence the workaround would be to remove CONFIG_SPL_FS_LOADER option from r5 defconfig and rebuild tiboot3.bin.

SDK 8.0 Issues:

• Please follow the below FAQ for fixing DFU 8.0 issues:

J721E SK Issues:

• Please follow the below FAQ for fixing J721E-SK DFU issues

The steps to flash to OSPI using DFU  are:

• Connect Host PC to the MAIN UART of the board and connect minicom to the first instance.
• Connect the USB Type C cable to the Host PC (Linux)
• Set the board to DFU boot mode.As an example,the setting for J721E board is attached below.SImilarly set for the board which you are using.

  • SW8[1:8]:1000_0000
    SW9[1:8]:0010_0000
    SW3[1:10]:0101_0010_10

• Power on the board
•  HOST SIDE:Execute the following commands

  • >sudo dfu-util -l
    >sudo dfu-util -R -a bootloader -D <Path to tiboot3.bin binary>
    >sudo dfu-util -R -a tispl.bin -D  <Path to tispl.bin binary>
    >sudo dfu-util -R -a u-boot.img -D <Path to u-boot.img binary>

• After executing the above commands on the host(PC),you will be able to see u-boot coming up on the board through minicom.
• As soon as u-boot comes up , click enter so that you can enter into u-boot .
• Now you can flash SBL bootfiles/SPL bootfiles to OSPI based on your choice by following the steps below:

------------------------------------------------------------------------------------------------------------------------------------

Flashing SBL bootfiles to OSPI :

• TARGET SIDE(BOARD):Execute the below commands:
  •  

    setenv dfu_alt_info_ospi 'tiboot3.bin raw 0x0 <size in hex>;tifs.bin raw 0x80000 <size in hex>;app raw 0x100000 <size in hex>;nor_spi raw 0x3fc0000 0x8'

• TARGET SIDE[BOARD]:Execute the below commands at u-boot.
  • NOTE:Ensure that the sf probe command shows NOR flash(Not NAND flash) 

  • >setenv dfu_alt_info ${dfu_alt_info_ospi}
    >sf probe
    >sf erase 0 0x400000
    >dfu 0 sf 0:0

• HOST SIDE:Execute the following commands

  • >sudo dfu-util -l
    >sudo dfu-util -a tiboot3.bin -D <Path to sbl_xx.tiimage file>
    >sudo dfu-util -a tifs.bin -D <Path to tifs.bin> 
    >sudo dfu-util -a app -D <path to app image>
    >sudo dfu-util -a nor_spi -D <Path to nor_spi_patterns.bin>

• Boot using OSPI boot mode

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

Flashing SPL bootfiles to OSPI :

• TARGET SIDE[BOARD]:Execute the below commands at u-boot.
  • NOTE:Ensure that the sf probe command shows NOR flash(Not NAND flash)   

  • >setenv dfu_alt_info ${dfu_alt_info_ospi}
    >sf probe
    >sf erase 0 0x400000
    >dfu 0 sf 0:0

• HOST SIDE:Execute the following commands

  • >sudo dfu-util -l
    >sudo dfu-util -a tiboot3.bin -D <Path to tiboot3.bin>
    >sudo dfu-util -a sysfw.itb -D <Path to sysfw.itb>    [Only needed for J721E board]
    >sudo dfu-util -a tispl.bin -D <Path to tispl.bin image>
    >sudo dfu-util -a u-boot.img -D <Path to u-boot.img>

• Boot using OSPI boot mode
