    Is there any error checking on the file transfer using the "load" command.

    Hi Carl,

    Can you be more specific by what kind of error checking you're referring to? Can you give me an example?

    Thanks,

    Hi Aaron

    What I ‘m hoping to find out is if “load “ (serial) supports a file transfer protocol that has error detection such as Xmodem or Kermit. A file transfer protocol helps to ensure that data is free of transmission errors.

    load does not support any file transfer protocol other than raw. load will print out the md5sum of the image that you load. if the image is continuous, you can compare the md5sum with the md5sum obtained on a raw binary file of your image on your pc. you can use the m68k-elf-objcopy command to create a binary image on your pc if your build environment is not producing one when it builds.
    Thanks,

    Hi Bruce,
    An SREC file contains checksum values within the records. Does load check these values, example: if a check sum value calculated on the received record does not match the value found in the record, will it generate a load error such as error “100 - bad checksum”?. Also is the syntax for a SREC load is “load srec”.
