Summary of change:
First Let's start with the pinout of the VEMS unit [http://www.vems.hu/wiki/index.php?page=MembersPage%2FMikeLough Pinout] image '''important wires''' * Power * Ground and '''GND5''' * '''Flyback''' * Serial connection ----- Done so far: * Power * GND & GND5 * Serial connection * Trigger, Confirmed it works with 60-2 trigger Can do other triggers as required. ---- Problems with Derricks board. #1, IGBT's intermittently grounding.. fixed #2, Trigger set for coil type w/ 60 teeth #3, attempted to upload new firmware: ---------- Fix for bootloader * Next on the list to try? ** try to enter BootLoader. A common problem is to forget about the fact that ECM does not enter BootLoader when rpm > 0. Make sure that RPM is 0, or try progl.pl 'f' flag or mcbfe instead of mcbff in the: *** ''Manmcbfecb'' command *** or loopback the ECM's serial conn at powerup (before connecting PC !) and try to talk 19200,8n1 manually say 'S', 'p', 'v' and expect something like "AVREFI1", "20", ... ** I always use something like *** ''perl bin/prog.pl vems.hex :COM5 Etwf'' to write vems.hex to flash on win32 *** ''perl bin/prog.pl vems.hex :/dev/ttyS0 Etf'' to verify vems.hex vs. flash on linux As a last chance, the bootloader can be downloaded with an ISP cable.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
