Hello Andy,

Thank you for the comments.

I reinstalled 7.50 and did another round of tests with 7.50 and 7.51.  Here are the findings:

• 7.50 and 7.51 do work with the option, "Assert DTR and RTS while COM Port open", ticked.
• 7.50 and 7.51 do NOT work, at least not reliably, without the option, "Assert DTR and RTS while COM Port open".

I did three fresh cycles of erase/program/verify for each version in the same Linux+wine environments and same USB RS232 cable.

I did not keep track of what options my previous failed tests were based on.  Sorry about that.

Well, I am still not sure what went wrong, but I am glad that Flash Magic works for a Linux guy like me. ^^

Just for reference:
# wine --version
wine-1.4.1

Hello Andy,

Thank you for looking into the issue.

Fist of all, I must admit that I am using Flash Magic on my Linux box on top of wine, which I believe is not officially supported.
It just seems odd that when the auto-baud stage is manually done, the rest of lengthy erase and program cycles is done properly.

I just downloaded the secret 7.51 on your website, where the web page says it's 7.50.
This version indeed works fine on the same Linux box+wine+USB RS232 combo!
Does Version 7.51 include the fix to the problem or is it just some random combination of board, cable, OS... that fixed my problem?

Thank you for keeping the tool improving. :-)

Hello all,

I just tried the Flash Magic to program my LPC1114 board.  However, it often fails at the auto-baud stage.  Yes, it sometimes passes the auto-baud stage, but rarely.  I always pull low the ISP pin and reset the board before trying a new cycle.

If I manually sync the baud rate with a terminal, the subsequent programming will go smoothly.
I am not sure what is going on.  I have attached the debug log, which I cannot comprehend, to help isolate the problem.

One thing to note is that when manually doing the auto-baud stage, the terminal will often echo garbled bytes when '?' is sent.
I have to try again with <ENTER> then '?'.  This may have to be tried several times.
When 'Synchronized' string is received, sending 'Synchronized' again will complete the auto-baud stage. 
ISP commands will then go smoothly.

If it is a hardware connection problem, I have no idea why the lengthy programming steps would go smoothly after a successful auto-baud.

P.S.  I tried the latest version, which is 7.50.

Thanks in advance for any pointers.


Brian
