Verify that programmer is latest version 3.22
Remove Miniprog & Target, re-boot your PC
Start Programmer (you even might select now device family as CY8C5xxxLP but that's not necessary)
Plug in MiniProg3, it now should show up in the "Port Selection" window
Set programming mode to "Reset", AutoDetect "On", use 5 pins, SWD, and select your board's supply voltage, do not power externally
Plug in yout board now, toggle power to "On", check for board's power LED
Select your project.hex file, buried deep in project's path\CortexM3\Debug(or Release)... etc \projectname.hex
Try a "Read" first and check for correct device and family
Device and family cannot be set in this stage when "Auto Detect" is "On"
Ive done hundreds of schmartboards and they can be troublesome for Miniprog3 to acquire. Sometimes Programmer will hang and you have to unplug miniprog3 many times before it will find the chip. Sometimes even reboot the program. Not all are like this. Just some.
Do what Bob says.
I usually power them from the Miniprog3 if there are not soldered to a board.
To find your hex file go to the blue folder at the top of the page. Click on it go to the location where you keep your program files and click on your program folder. The folder will be named something like Design1.cydsn. Click the Cortex file. then click the Arm file. Click the Debug File and you will find your hex file. Click on it and Programmer will know where to find it. You dont need to find it again if you are editing your program and make changes. As long as it still shows in the file path at the top of the page it will load the changes.
Watch your settings on programmer. Sometimes they will change all by their selves. If it hangs, minimize your windows one at a time. There is probably a popup open that is preventing Programmer from finding the port. You have to have a little patience and wait for programmer to load before trying to acquire a device. Otherwise it will hang.
If you use auto detection. Programmer will detect the device for you. If you want to select the device Your self you need to use the CY part number of the device that is written on the top of the device.
I finally got everything to work. It was a combination of problems. Mainly due to learning curve on the way that Cypress expects you to do things. Thanks to everyone who responded.
1) Unclicking Auto on PSoC programmer *still* does not list PSoC 5 family in the dropdown list boxes, version 3.22 of PSoC programmer. However, since PSoC Creator programs the device directly, not using PSoC programmer, was able to work around that. You have to unclick auto on the PSoC programmer to enable the dropdown. In Auto, once you get MiniProg3 working, PSoC programmer still can't see the PSoC5LP devices or program them. Moral of the story: Don't use PSoC programmer with PSoC 5LP devices yet.
2) The USB connector for the SchmartBoard *sucks*. It almost works with some USB cables, not with others. Finally went with the 7805 onboard 5v regulator and external power supply and got it to power up. It was intermittently running previously. Took me a while to sort that out, it *didn't* help the miniprog3 issues. Moral of the story: Assure steady power to your PSoC 5.
3) The MiniProg3 selection dialog under PSoc Creator has a "right clickable" setting for the MiniProg3 list line that allows you to select the connector that MiniProg3 uses, among other things. Turns out that MiniProg3 *has* to have the right connector selected. It is unable to auto detect. That is ok, that is how it was built. However, it initially was not obvious to me, even after scanning the troubleshooting guide. You can also get to the "Configure" right click menu item by pushing the "Port Setting" button on the Select Debug Target Dialog.
In addition, if you got one successful detection, even if incorrect, on the MiniProg3, you can't get that dialog back up unless you unplug the miniprog3 from the PSoc5 device. Minor inconvenience, but confusing while on the learning curve. It shows up if you change targets between programming sessions. Duh!
4) Once you get past all of these items and understand what they are doing, the Cypress devices are quite good. The LP versions work far outside of their temperature boundaries.
