TDA4VM: TDA4 custom board bring-up tip

Sung-IL

Part Number: TDA4VM

Dear Champs,

My customer developed TDA4 custom board and trying to make bring-up the board.

When I checked the TI-RTOS SDK UG in below, I found only SD Card boot and QSPI boot, and could not find UART boot.

Is it possible to download SBL image through UART to check if SBL is working on custom board?

Could you please provide a guide how we can make board bring-up in TDA4 case?

Is the only way to attach JTAG?

Thanks and Best Regards,

SI.

    Hi SI,

    Are you looking for other options as you don't have a SD card interface and also an external flash?

    I'm checking with the team if we have some kind of a document which we can share.

    Regards,

    Karan

    SI,

    The TDA4VM device supports UART boot. See chapter 4 of the device TRM, specifically section 4.6.10.1. It is basically an XMODEM download from a host PC to the TI device target, using a terminal program. You just need to set the boot pins to select this as the boot mode, either as primary or backup boot mode). Often times these "recovery" boot modes (peripheral driver modes like UART, USB, and Ethernet) are set as the backup, with some memory (non-volatile flash) interface set as the primary boot mode. That way if the flash memory is empty or otherwise corrupted, the device goes to the backup mode for a possible download and recover.
