TDA4VH-Q1: J784S4 UART Mode Boot

Part Number: TDA4VH-Q1
Other Parts Discussed in Thread: TDA4VH, TDA4VM

Hi,

Could you check below issue and provide the boot file for u-boot on uart mode if you have?

Intended operation is as below.

1. sb --xmodem $OUT_R5/tiboot3.bin > $UART_BOOT_MCU_UART < $UART_BOOT_MCU_UART

2.sb --ymodem $OUT_AXX/tispl.bin > $UART_BOOT_MAIN_UART < $UART_BOOT_MAIN_UART

3.sb --ymodem $OUT_AXX/u-boot.img > $UART_BOOT_MAIN_UART < $UART_BOOT_MAIN_UART

After 1, it received CCCC on $UARTR_BOOT_MAIN_UART.

However 2 is not excuted.

When customer use minicom or sx, issue is same.

Please guide this issue.

    Hi David,

    Can you try following the steps mentioned from  slide 8 in the below link: The below steps are for TDA4VM, but the same steps can be followed for TDA4VH.

    Just had a couple of questions as well:

    Is this a custom board or TI J784S4 EVM?

    Are you using LINUX SDK / RTOS SDK?

    Were any changes made to the device tree?

    Are the prebuilt binaries from the SDK used or were there any changes made on top of the default SDK and the new tiboot3.bin, tispl.bin and u-boot.img binaries recompiled and used.

    Best Regards

    The board under test is the TI J784S4 EVM, and we are using LINUX SDK 11_00_00_00.

    There have been no device tree changes, and both the pre-built version and the newly built version have been tried.

    After transferring tiboot3.bin, we confirmed the 'CCCC' output from UART_BOOT_MAIN_UART.

    However, when issuing the YMODEM transfer command for tispl.bin, the transfer fails.

    # SW11[1:8] 0000 0000

    # SW7[1:8] 0111 0000

    # SW2[1:8] 0xxx xxxx

    Hi jongkyu,

    Just to confirm, is it a GP device or is it an HS-FS device  or is it an HS-SE device?

    If it is GP device, you will have to use tiboot3.bin binary from prebuilt-images folder.

    If it is an HS-SE device, you will have to use tiboot3-j784s4-hs-evm.bin binary from prebuilt-images folder.

    If it is an HS-FS device, you will have to use tiboot3-j784s4-hs-fs-evm.bin binary from prebuilt-images folder.

    Can you try following the steps mentioned from slide 8 in the below link: The below steps are for TDA4VM, but the same steps can be followed for TDA4VH.
