UART BOOTLOADER

Other Parts Discussed in Thread: HALCOGEN, TMS570LS3137

Hi,

I am using TMS570LS3137 HDK Board, CCS v7.0.2, Halcogen 4.6. I am trying implement uart bootloader by using F021_API v2.00.01. If i send  .bin file through Hyper-terminal-->send file-->example.bin  + ymodem--->send, it will come out of program with message 'Aborted by user'. Attached sys_link.cmd file.1526.sys_cmd.txt

    Hello Vinayaka,

    I believe the bootloader has a series of commands and communication structure that have to be followed. These are outlined in the application note. I don't believe you can simply send the binary via a terminal window like this. It will have be a series of command packets and data.

    Hi Chuck,

    Thank you for response

    1. What is the correct way to send .bin file to controller? I have referred this attached file for uart boot loader. In this they have used y-modem to send .bin file.

    2. I will try to explain our application requirement, we are using TMS570LS3137 controller which is connected to WIFI module. TMS SCI is connected to UART of wifi module. When i send .bin file from laptop to wifi module (using any TCP or UDP protocol) which is received in TMS through SCI. I want to upload these received data into TMS flash using UART boot loader. I want to change these UART Boot loader  application (attached file) as per my application.8304.SafetyMCU_Bootloader.zip?

    Hello,

    You can send a raw binary file to the device through uart bootloader.

    In TeraTerm terminal,  File -> Transfer -> Ymodem -> Send, then browse your bin file for transferring.

    Please try this bin file, it works on my board.

    Hello,

    It may be caused by timeout. In your application, one WIFI module is connected to TMS570 MCU through SCI, and yu want to download file from PC to WIF module, and from WIFI module to TMS570 MCU. Can you try to download the binary file to TMS570 MCU directly from your PC?
