Hi All -

I've run into a strange thing over the weekend that has me stumped. Before we go into it, it could all be operator/technician error!!

I have a prototype set of boards that I designed for a new product. I received Qty 5. The board was design to ONLY used SWD and has a connector for the Mini-Prog3 end plug.

I soldered up and successfully programmed and tested Qty 2 with -LP035 datecode 1301.

Then I wanted to test two more boards but was out of -LP035 chips. I had Qty 2 of -LP032 datecode 1243. I soldered up those boards and went to program and test. I have tried both boards with PSoC Programmer 3.17 and PSoC Creator 2.2. Both do not even show a chip present etc. I did change the device in the project and rebuild.

Has ANYONE programmed a -LP032 in SWD mode?  I'm worried that perhaps most testers use JTAG and this chip may have problems with SWD only.

I've searched www.cypress.com and the forums for any discussion about it but did not find anything.

A confirmation that someone (Cypress) has programmed this chip in SWD mode would be helpful.

Update:

as i said it could be operator error. it appears that the miniprog3 is fried. i can not now go back and program the original prototype or the two pre-production units with LP035 on them.

i will FedEx another miniprog3 in and see if i can proceed.

just an update. i fedexed in two programmers for early morning and everything is working fine. i had 24V->5V DC-DC converter let go on one board and it must have fried the miniprog3.
