SREC file detects like Binary/Raw format

evgenik — Mon, 20 Jul 2020 16:07:15 GMT

Hello.

I am working with Kinetis K21FN120 MCU.

I wrote a C Sharp language program to create .srec files. This is a necessity for our project. All conditions, such as file format, checksum calculation, addressing, were complied with according to the technical documentation of the Motorola file. Nevertheless, when I tried to write the .srec file built by my program through Freescale "Flash File To Target", Freescale cannot determine it as a Motorola S-Record file but sees it as Binary/Raw format.
I even tried to get the file generated by my program and copy it to a file generated from IAR, which was previously detected as Motorola S-Record file. After copying, the result is the same as with my file: it is seen as Binary/Raw, not Motorola S-Record. So I thought there was some kind of problem with encoding.
Please tell me, this is an ordinary text file with the extension .srec, encoded as UTF8. Where to look for an error?
Thanks
Evgeni

Hi Evgeni,

I think you have written the content of your file in a wrong way. I suggest that you check/read it with srec_cat (see Generating Intel Hex Files with a given Length using srec_cat | MCU on Eclipse ) or check it with srec_info (see CRC Checksum Generation with ‘SRecord’ Tools for GNU and Eclipse | MCU on Eclipse ).

Other than that: post your file here.

I have added both files for comparison. As you can see they are identical. But file from IAR is detected like Motorola S-Record file and file from my application is detected like Binary/Raw format file.
I have checked my file with srec_info and have received the next warning: "ignoring garbage lines". How can I found these lines? Why compare images found that both files are the same?

Hi Evgeni,

sorry, I did not realize that you already had provided the files.

I checked them, and the files are not the same.

You can easily see this with EHEP in Eclipse (5 Best Eclipse Plugins: #4 (EHEP) | MCU on Eclipse ):

So your generated files starts with binary data (EF BB BF) (Unicode byte order mark): simply store that file as a normal ASCII file instead.

I hope this helps,

Erich

Hi Erich.

After making some changes in my program, when working with srec_info, I issued the same warning indicating the problematic line number. After a detailed analysis of this line, I found an error in my code and fixed it. Now my file is detected as a Motorola S-Record file.
Many thanks for the help.
