I won't change the max start cycles. There must be something wrong with your coil. You know that your coil is hard switching during startup?  ;)

But you can do it yourself, don't set values over 254, it is only a 8 bit counter:

I finally finished my new coil, can't wait to test it at the lab with more space (and maybe Netzpfuschers coil too)

Setting it up was so much easier than with more basic drivers too.
Just hook up the primary and run the autotune to see if it is tuned right, and that's it :D
No messing around with an oscilloscope, the feedback polarity, or tweaking potis to get the lead time correct. Just type in the numbers and the coil works, pretty awesome to be honest.

Thanks! Yes, you were right. Something was wrong with a coil. After deep analysis I found that my flashovers from previous test some way burnt sensor's comparator or +\-12v supply driver chain. After I cut out all peripheral driver part the signal became looking good.

Anyway, I choosed secondary and primary inductors for mmc I have and looks like the impedances is not matched good. Result of 20mS under 60A current limit is about 10-15cm spark.


Nevertheless I want to try to oscilate whole coil on start freq because I see the coil grab a feedback and sometimes jump between poles and I do not see another way besides to force a coil to sometimes hardswitch through the whole freq sweeping down under spark loading so please if you can change the start cycles counter to 16 or 32 bit I will be very appreciated.

Netzpfuscher pointed at the place where the range can be changed - treat it as an opportunity to learn how to modify and compile the code (PSoC creator is freely available from Cypress semi).

My apologies.
