Message: 53907    Hello all,

Fatal Kermit Protocol Error: Too many retries


HINTS... If the preceding error message does not explain the failure:

. Try changing the remote Kermit's FLOW-CONTROL setting.

. Adjust the timeout method (see HELP SET SEND).

. Increase the retry limit (see HELP SET RETRY).

. Try it again with SET STREAMING OFF.

. Try it again with SET PARITY SPACE.

. As a last resort, give a ROBUST command and try again.


. Be sure the source file has read permission.

. Be sure the target directory has write permission.

(Use SET HINTS OFF to suppress hints.)


  Please try to find solution early. I am not able to transfer the file from four to five days.And I am just working only on this.

Hi pranay,


can you explain the steps that you've carried out so that it would be helpful for me to sort out your problem.


How did you program the flash memory.


Are you using the serial cable that follows the instructions mentioned in blackfin.docs.


Explain the process in a stepwise manner.
