Re: [OpenOCD-devel] OpenOCD PSoC4 flash driver

[Tomas V. <to...@us...>]

Oh yes, version 2 of KitProg complicates it further as the USB protocol 
substantially differs.
I'm not aware of any documentation on it - ask Cypress.
Are you volunteer to implement KitProg2 protocol in OpenOCD?
BTW KitProg(1) driver was reverse engineered, no doc as well.

Although not working 'reset halt' does not mean you cannot use OpenOCD.
I usually use KitProg2 in CMSIS-DAP mode. Of course you should avoid
to do some setting which can potentially block SWD (GPIO on SWD pins and 
CPU clock)
too early - a half second delay at very beginning of main() is a good 
safety measure.

Another idea is to buy a cheap ($10) CY8CKIT-043 (PSoC4M) or CY8CKIT-059 
(PSoC5LP),
break off the KitProg part and use it as an external adapter.
