Other Parts Discussed in Thread: SPRC074

hello,

 

I need to implement a firmware update through serial link on a LF2407A. i tried using TMS320LF240x-A flash programming documentation. i downloaded sprc074 but i can't download the kernel because i do not know whihch file is the kernel and serhost.exe runs only on windows 95or 98. is someone able to tell which file is the kernel and some more information on how to send the kernel.

 

thanks

    Hello.

     There are some files in the folder (after installing "sflash240xA.exe"):

    clr24_x1.hex

    era24_x1.hex

    krnl24xx.hex -- this is the kernel.

    prg24_x1.hex

    serhost1.exe / serhost2.exe -- these programs work on Windows XP and Seven and support COM1/COM2 ports.

    f240_hex.exe -- utility for convert out-file to hex.

    Readme.pdf -- you must read this manual.

    CCS (afer compilation your program) makes out-file (test.out).

    The utility makes hex-file "test.hex" in COFFv1-format (command line: f240_hex.exe test.out).

    Now you must connect "LF240xA" (SCI interface) to PC over RS232 or  virtual COM-port and run "serhost1.exe" or  "serhost2.exe " (command line: serhost1.exe test.hex).

    Don't forget reset "LF240xA" and press a key for boot.

    I have a question too:

    Where can I find (download) source files for program "serhost1.exe" ("serhost2.exe") ?

    Who knows, tell me please.

    Thank You very much for your help.

    I just mention that file name must not exceed 7 characters for f240_hex!

    I am also interested in source files for serhost1.exe

     

    regards,

    Olivier.

    Did you ever get the source code from somewhere? I'm highly interested in that as well.

    No, I haven't this source code. And do you have it?

    Anybody, please, help us !!! :)

    Unfortunately no. I'll let you know, if I got it.

    How did you solve flashing with a serial interface in the end?

    We used a usb-uart converter (ft232rl, virtual com-port) and our program for pc. Also I used "serhost1.exe" or  "serhost2.exe". 

    We programmed LF2403A DSP (not LF2407A).
