And for those who does not find the 9.xxx Mhz oscillattor try the 10 Mhz that worked for me, and I use a 7805 and Sun, 01 Jun 2008 15:40:02 GMT Jim Willette http://groups.yahoo.com/group/68hc908pgm/message/1799 http://groups.yahoo.com/group/68hc908pgm/message/1799 Congratulations Sebastion   Your perseverance paid off. I am happy to hear you were able to get your Megasquirt programmed and responding. ...

But allways was burning ok prog08sz. Now I Sat, 31 May 2008 03:23:20 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1797 http://groups.yahoo.com/group/68hc908pgm/message/1797 Well I answer yours questions. ... if memory serves me correct you can verify the code on the chip with the file you programmed it with in order to determine Fri, 30 May 2008 20:03:36 GMT Jim Willette http://groups.yahoo.com/group/68hc908pgm/message/1796 http://groups.yahoo.com/group/68hc908pgm/message/1796 Sebastion,   Its been a long time since I worked with the programing software, but if memory serves me correct you can verify the code on the chip with Fri, 30 May 2008 19:46:22 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1795 http://groups.yahoo.com/group/68hc908pgm/message/1795 I have just tried but the boot> prompt does not appear, it is dead. I tell us that my cable y ok, and the max232 was testead and is ok. could I test on the Thu, 29 May 2008 19:52:21 GMT Jim Willette http://groups.yahoo.com/group/68hc908pgm/message/1794 http://groups.yahoo.com/group/68hc908pgm/message/1794 Sebastion.   Try using the loader mode on the megasquirt with hyperterm connected to the megasquirt check your serial port rate. See if you get the loader Thu, 29 May 2008 18:10:30 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1791 http://groups.yahoo.com/group/68hc908pgm/message/1791 here are the boot.s19 and the mega.s19 I am uploading, maybe I compiled wrong. I do not know ****boot start here S113FB0002C0038402D003D14FC7FFFF6E011E6EF3 Thu, 29 May 2008 18:02:05 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1790 http://groups.yahoo.com/group/68hc908pgm/message/1790 Well I tried with 2 cpueater.exe and I burn it ok, is better but when I put it on the mega board it does not work. I make a mistake my verion of prog08sz is Thu, 29 May 2008 17:48:56 GMT Colin Gebhart http://groups.yahoo.com/group/68hc908pgm/message/1789 http://groups.yahoo.com/group/68hc908pgm/message/1789 I have no idea if this will help anything, but if Jim's second suggestion is right and your computer is too fast, this program will slow it down. It worked Thu, 29 May 2008 16:54:04 GMT Jim Willette http://groups.yahoo.com/group/68hc908pgm/message/1788 http://groups.yahoo.com/group/68hc908pgm/message/1788 Sebastion. you are getting there.   I would suspect serial timing issues using a 10mhz crystal.   Also what computer are you using older slower Thu, 29 May 2008 00:22:33 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1787 http://groups.yahoo.com/group/68hc908pgm/message/1787 Hi I am back, I just finish mi pcb and I try to program. First of all I tell us what I am running: Is the same circuit but I add an 7805 and a switch to Mon, 26 May 2008 15:04:32 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1786 http://groups.yahoo.com/group/68hc908pgm/message/1786 Hi in the notes of this group I read that if I dont have de 11 volts od the serial port I should put a 9v battery to the collector of the transistor. Thats ok, Thu, 22 May 2008 15:52:50 GMT jimw1024 http://groups.yahoo.com/group/68hc908pgm/message/1784 http://groups.yahoo.com/group/68hc908pgm/message/1784 ... have ... The easiest way is to use an oscillator. You would have to re-design the circuit to use a crystal. Look on the freescale.com com site for info on Wed, 21 May 2008 17:44:27 GMT sebastian_mascolo http://groups.yahoo.com/group/68hc908pgm/message/1783 http://groups.yahoo.com/group/68hc908pgm/message/1783 Hi I was ready to program mi 68hc908 but I noticed that I bought a cristal and not a oscillator like the circuit. Is there any way to use a cristal of instead
