Newcomer here needing help with the PRO7B16N.exe. I am reviving an electric van made by Chrysler in the early 90. Long story short: motor speed and regenerative braking is managed by a HC05 controller. Unit has 68HC705B16 socketed and program appears to functioning properly but one of the IO pins is stuck at 1.6V. There's no source code available that I could find but I was able to build a programmer board and read out the eprom contents. Now I'm trying to use the PRO7B16N.EXE that I down loaded from freescale to program the new replacement 68HC705B16N. I have manually prepared an S-record file for programming the part. The pro7B16.exe communicates with the target part and I can read back various memory locatons. However, when I try to write to eprom, the s-record file name that I enter will not be read. The error message returned is:
"Cannot open file" . I've tried all the obvious stuff like using full path names to no avail. Any help would be appreciated. I'm so close to getting this vehicle back on the road.
