 Today I updated from Creator 3.0 SP2 to 3.1, and since then I haven't been able to get a board using a Cypress USB-UART bridge to show up in Bootloader Host. It shows up in Device Manager, but not in Bootloader Host.

   

 

   

I have unstalled everything Cypress and reinstalled 3.1, but still no luck. Any ideas before I uninstall 3.1 and reinstall 3.0?

You probably do not need to re-install 3.0, it should still be in your program-folder.

   

Sure that no filter in Bootloader Host hinders the com-port to show up?

I just checked with a brand new Prototype Kit on my win7 system:

   

 

   

Starting Creator 3.1

   

Inserting Board, drivers get installed

   

Removing board

   

Insert Board while pressing the switch. Blue LED blinks

   

Starting BootLoader Host, on my pc com28 is automatically selected.

   

Setting baud-rate to 15200

   

Test programming successfully

 Yup, no filters are active, and I can see other serial ports in the Bootloader Host window, just not this one. I was programming it with no issues before updating, as was a friend.

   

 

   

As part of trying to figure out what was going on I uninstalled everything Cypress, and then did a fresh install of 3.1. I still can't see the board in Bootloader Host. Before I did that I tried to use the 3.0 Bootloader Host, and it no longer worked either.

Not sure if this impacts your design, from 3.1 release notes -

   

 

   

Default Stack and Heap Sizes
The default stack and heap sizes for new projects have been adjusted to more closely match real-world
requirements. When new projects are created, the stack size is set to be a fraction of the total SRAM in
the target device. The heap is set to a small value - 128 bytes - for all devices. You can, of course, modify
these settings in the Design-Wide Resources System Editor. For example, if you are not using any heap
based memory allocation the heap can safely be set to 0 bytes.
Note that some example projects and application notes were originally created on older versions of PSoC
Creator and use the larger default sizes. These projects will continue to build and run perfectly because
they have sufficient memory allocated. However, if you attempt to reproduce the example yourself in your
own project you may need to adjust the stack and heap. However, the example documentation will not tell
you to do that because the original project did not require the settings to be changed.

   

 

   

The heap and stack size were reduced in 3.1, try restoring to 3.0 levels 4K and 16K respectively.

   

3.1 default settings are now 128 bytes and 2K.

 Hi,

   

 

   

I'm begginer in PSoC and I'm using a CY8CKIT-049. I had tree times already this issue. I don't know why exactly happens, but one of the reasons is... because to try your design each time you need to UNPLUG the PSoC from the USB, press and hold the button to enter in bootloading mode and PLUG the PSoC back into the USB port. Imagine how many times per day I PLUG and UNPLUG the device!  You can see and manage the PSoC with all the other software provided from Cypress, but ONLY BOOTLOADER HOST can't !

   

 

   

SOLUTION to this problem is to go to device manager and DELETE (not just uninstall) the drivers for PSoC, RESTART your PC. Go to location where is your Creator installed, find USB-Serial SDK,  go to DRIVER (not Cypres usb- serial driver) and REINSTALL your drivers. You should see a Command Prompt window during the installation.

   

 

   

P.S. CY8CKIT-049 for 4 buck's is a great device, but is not verry user friendly, specially for people like me. Will be verry nice if is possible to be programmed from the creator witout the need of DESTROYING the USB bort.

Is there any other solution to the problem.

This thread is more than half a year old, better to start a new one with some detailled description of your issues-
