I have several identical custom PCBs with CY8C4245-AXI and several Miniprog3 programmers.

3 Miniprog3 are rev B, one is Rev C.

Using a rev B miniprog, I can program all boards.

Using the rev C miniprog, I can only program 6 out of 9 boards. The other 3 boards can not be programmed.

According to PSoC programmer, all miniprogs have the same firmware version.

I use SWD, 5 pin connector 1.6MHz, reset mode.

When programming fails, it takes very long (minutes), nothing happens, then I get a message that only says that programming has failed.

I use completely the same equipment (same laptop, same cable, same PCB), and when I exchange the Rev C miniprog to the Rev B miniprog, programming works.

Any ideas why the problem occurs? Note that the 9 PCBs are (i.e. are supposed to be...) identical.

Can you please share the screenshots  of PSoC Programmer with  the error  that you get when you program using MiniProg3 RevC and MiniProg3 RevB
