Hi

The GUI-version of Flash Magic supports JIT-modules specified in the menu: Option->Advanced Options->Just In Time Code tab. Here one can type in the JIT-Module path and Options.

How can JIT-modules be called when using the command line version (FM.EXE) of Flash Magic ?

With thanks in forward...
Kind regards

Hi,

I have rewritten the "JIT Examples/Simple Serial Number"  C-code, which follows the FlashMagic tool, in order to work with the ARM based LPC2378 cpu. The original C-code was limitted to program the serial number in a 16bit flash address range (0x0000...0xFFFF) for the 8051 family. It is now possible to program a "Just In Time serial number" into the full 32bit flash address range (0x00000000...0x0007FFFF), which requires use of INTEL HEX record types 4 and/or 5. The C-code is still working for 16bit address ranges as 8051s.

The modified C-code works perfectly, but I do not fully understand some few parts of the original code. I have studied the Flash Magic User manual and found only a little about JIT modules.

In the original C-code file pointers and arrays below are defined:

  FILE *commandfile;
  FILE *datafile;
  FILE *userfile;
  char datafilepath[2000];
  char userfilepath[2000];

In the User manual for FlashMagic on page 50/51 under the section "7.5 Just In Time Code" following is written:

executablename
commandfilepath
datafilepath
userfilepath
option

My questions are:

1) Can somebody explain the connection between these terms and the C-variables ?

2) I can't find any .hex file generated by the serial numbering JIT module.
    Is the serial number hex information placed in a file or generated by FlashMagic on the fly ?

If it is of interest for this forum I can upload the modified Serial number JIT module including source code to this web site...

Kind Regards
