TMS320LF2407A: TMS320LF2407A- readback

Kadirov,

            LF2407A is supported only in CCS3.3. Later versions such as 5.x/6.x/7.x/8.x do not support LF2407A. There is no C2000ware support for this device either.

I presume this is what you want to do:

You have an unsecure LF2407A device (that is, a device not protected by passwords). You would like to copy the contents of the flash memory and program it in another LF2407A device. If this is correct, it can be done easily as follows:

Save the contents of flash (Starting address: 0000h, Number of words: 8000h) using the File-->Data-->Save option as a COFF file (a file with .out extension). Once you have this .out file, you could use the "Flash plug-in" available in CCS3.3 and program the new device.

Please dump the entire flash content as a .asm file, assemble and link it again to produce a “new” .out file. You should be able to program this .out file.

Details:

Save the flash content as a hex file and then append a “.word” before every word (and a “h” after the word) like below:

            .text

            .word  1234h

            .word  ABCDh

            .word  2587h

            .word  1D74h

            ………..

            ………..

(The linker command file should be identical to page 3 of the attached PDF file.)

If the assembly method explained above does not work, try the C method shown in the attached file.

Hello

I did all as described in pdf instructions. files .c and .cmd added to a new will cover and pressed to build, in the log only two errors -pd and -ps as described ignored. but in my folder debug not created files .out and .map.

how do i add my files to my posts or please give me your mail

Please try the assembly file (xxxxx.asm) approach first. That is, create an assembly file and try to assemble/link it. It is a simpler option than creating a C file. You can attach a file to the post by the method shown in the attachment.

Really nobody tried to copy flash memory 2407a?

   Please try the attached fileskadirov.asm

2262.D.zip

Kadirov,

            Please confirm if you were able to program the .out file into flash. The zip file I posted yesterday contains the .asm, .pjt & .out. I left out the linker command file, which I am attaching to this post. (Please change the extension form .txt to .cmd before using it). With the files I have provided you, you should be able to assemble/link the .asm file to create a .out. In order to be able to use the .pjt file I had sent yesterday, you need to create a directory called \240xA in C: and copy all the files I have sent you into that directory.

tomorrow trying with your linker. With my linker flash memory is programmed but not the device does not work. I tried to remove the flash memory (M95256) and EEPROM (AM29LV400BT) and programmed with the programmer and everything worked. I tried again with another device but without result. Programming with CCS3.3 is normal, but after the RUN command all flash addresses change and the device does not work. Thanks for the patience of my problem

Hello Mr. Hareesh J. I want to describe in detail my equipment. This is a frequency converter for the DC motor from the machine for textile production TRUTZSCHLER. The inverter has various errors, and when checking it, I did not find out the problem except the processor and so I wanted to replace the processor and explain the cause of the failure. Yesterday I created a .out file from your linker and everything went well. After programming, I compared the memo from 0x0000 to 0x8000 and everything was the same. But after restarting in memory 0x0000 to 0x8000 everything changes and is set as if by default.

I want to note that when choosing On-Chip Flash Programmer CCS gives an error

There are 3 switches on the board and all positions are OFF. If you switch to the ON position and connect and select the On-Chip Flash Programmer then there is no error. I screwed these switches to datashit

S97.1- boot_EN_XF//

OFF=Flash Execute

On=Boot ROM

S97.3-Vccp

OFF=0V

ON=5V

S97.2-MP/MC

OFF=On-Chip Flash Memory (Sectored) - if MP/MC = 0

ON=External Program Memory - if MP/MC = 1

But if everything is correctly programmed then it is possible and without switching the switches to the ON position, select On-Chip Flash Programmer and without warning you can enter the programming window

After unsuccessful attempts to program, I took EEPROM and FLASH MEMORY and reprogrammed it with my programmer, as I wrote after reprogramming and restarting the processor everything from 0x0000 to 0x8000 was set to other values but after I connected with CCS3.3 and chose the RUN mode in and everything became like in my firmware and the miracle worked. I wanted to find out the reason and tried to reprogram EEPROM and FLASH MEMORY on another device but it got out.

If you remove the FLASH MEMORY and connect to the CCS then all addresses except SARAM 0x8000 to 0x8800 only FFFF

e2e.ti.com/.../fault.rar

Information LEDs for faulty programming

e2e.ti.com/.../OK-WORK.rar

Information LEDs with good programming

I will continue to try, if there are any ideas, please let me know

I tried again to start my board and when the power was turned on, the LEDs did not turn on and I connected with the help of CCS and clicked on the Reset CPU and after Run Free. And everything starts and works. After restarting, everything was normal. What could be the problem?

Kadirov,

My ability to help you is limited to issues in LF2407A device. I do not have any knowledge on the rest of your system, so I am unable to help you in that area. Are you convinced that you were able to successfully reprogram the flash memory of the LF2407A with the files I sent you? If that is the case, then I am unable to help you beyond that.

You can easily verify if the flash image you programmed is correct by comparing it with the image in a known-good device. Please save the flash contents as a hex file across 2 devices and then you can compare if the programmed image is correct.

For normal operation, you want the following:

BOOT_EN/XF = XF

VCCP = 0v  (5v is also OK, but typically that is used only for programming)

MP/MC = MC

Mr. Hareesh J how to read or write my firmware in .bin or .hex format to external flash memory using XDS510PLUS and CCS3.3 or other soft
