I get the same error you are seeing, on the Philips Flash Utility V2.2.3, however the Flash Utility claims the second file loads even with the error. Does it run?

Does your development environment have any checking for incorrect memory addresses?

Let's take a closer look at the bad hex file with two highlite lines below . Blue color indicate address filed, red for record type, green for data. You see the very first line and the third to the last sharing the same address and record type. This is the problem i believed when it tried to write data to the previous spot in the flash memory which will not allow prior to erase. I would remove the third line to the last, and try to load again see if it take it.

it actually does run. at the time i didn't think it would but i found a bug in my firmware.

Does your development environment have any checking for incorrect memory addresses?

incorrect how?

thank you both for your replies & explanations! i appreciate the refresher on intel hex format...it's been a long time since i used that stuff but i think you're on to something. i don't have the source here but i bet it came back as soon as a set up a global variable...resulting in me getting a code segment or something along that line. probably some code seg config is required. will advise.

i guess i'm in "Make File hell" even though i left them as in the example. i'm using the suggested gnude.

interesting: this problem seems to have been triggered by defining a global variable. (i use them only with restraint.)

i fooled with the simple.cmd file until it worked. do you have any resources for more "enlightened" ways to edit these files. i merely guessed...dangerous.
