Andy,

For ISP operation during a data frame send/echo sequence, if a valid data frame is sent from FM to the device and the device does NOT return the proper data frame back in its echo, what is the expected outcome?

I am seeing a bad data frame returned from the device, but the transfer operation continues until the checksum sequence fails. Is there any way to generate the failure on a bad data frame and have FM retry at that point. If you are transferring a large data frame its takes awhile until it fails.

I guess I dont understand the purpose of the data frame echo from the device to FM if it is not even checked for the expected number of bytes. What is the point of the device returning the echoed data then?

This application is custom and uses the FM .dll.

Thanks.

Question:

Does Flash Magic (and the .dll) follow the Intel hex file line by line or does it search for the lowest address to start its load (I want to modify the Intex hex file to burn sector 0 last by locating sector 0 hex file lines last)?
