Code download through SCI interface

Other Parts Discussed in Thread: TMS570LS20216, TMS570LS3137, TMS320F28335, UNIFLASH

Hello,

We are using TMS570LS3137 and TMS570LS20216 processors and want to code download via SCI interface without using Emulator/JTAG interface.

What is the procedure for downloading the code via SCI interface without using JTAG interface? Is it possible? 

regards,

johnson

    Hello Johnson,

    There are several boot loader examples for the TMS570LS3137 that could also be ported to the TMS570LS20216; however, the TMS570LS3137 uses the F021 Flash API library where the TMS570LS20216 will use the F035 Flash API library.

    Here is a link to the UART bootloader application note which has a subsequent link to the example code www.ti.com/.../spna193.

    There are also other examples for CAN and SPI bootloaders listed in the application notes on the TMS570LS3137 product page.

    Note that these solutions are only useful for a firmware update. The initial programming has to be completed via JTAG.

    Thank you Chuck.

    But our concern, we don't want to use emulator option to download the code in production environment.

    We are using TMS320F28335/235 DSP also, since it has in built SCI boot loader without emulator I think we can flash the device through SCI.

    regards

    Hi Johnson,

    Unfortunately, the Hercules devices do not have any built in boot loader so the only way to do the initial programming is to either use JTAG with Uniflash or to use a 3rd party programming tool like one from BP Micro, Data I/O, etc.

    Another option might be to use a contract programming house that could program a bootloader into the device for you but this would have to be set up and managed by your organization. TI does not provide this type of service.
