Hi,
I am using both the GUI and command line to upload a hex file. To attempt to ensure both operations are the same I use the 'File->Save Command Line Directives' command. The command line is:
FM "COM(3, 57600) DEVICE(LPC1788, 0.0, 0) HARDWARE(BOOTEXEC, 50, 100) ERASE(DEVICE, NOPROTECTISP) HEXFILE(test.hex, NOCHECKSUMS, FILL, NOPROTECTISP)"
Using the GUI the operation takes about 1 minute. Using the command line it takes 6.5 minutes.
Is there any explanation for the difference? Why is the command line version so slow?
Thanks,
KenA
The GUI and the command line don't actually perform the ISP operations. Instead they both pass it on to the same DLL, so the same code is running in both cases.
Please double-check that the command line options match the settings in the GUI. If that doesn't help post back.
Andy
The difference was 'FILL' vs 'NOFILL' :-)
Thanks Andy!
Hi Kena,
We double-checked this with the current version and wasn't able to reproduce the problem. When "Fill Unused Flash" is unchecked the save directives feature generates "NOFILL". When "Fill Unused Flash" is checked it generates "FILL".
Can you please give us the steps to reproduce the problem? Thanks.
Andy
Hi Andy,
It was my error. The command line I was using was _not_ the same as the one generated by the GUI via "save directives", as you were hinting. "Fill unused flash" was not selected in the GUI but in my command line version I was specifying 'FILL'. So it was
FM COM(3, 57600) DEVICE(LPC1788, 0.000000, 0) HARDWARE(BOOTEXEC, 50, 100) ERASE(DEVICE, PROTECTISP) HEXFILE(test.hex, NOCHECKSUMS, FILL, PROTECTISP)
versus
FM COM(3, 57600) DEVICE(LPC1788, 0.000000, 0) HARDWARE(BOOTEXEC, 50, 100) ERASE(DEVICE, PROTECTISP) HEXFILE(test.hex, NOCHECKSUMS, NOFILL, PROTECTISP)
Sorry for the confusion, and thanks for the help.
