USB Superspeed Peripherals

Hi,

I have an FX3 device and it is properly programmed by the included Cypress USB Control Center.  I have downloaded and compiled the USB Control Center Source via the SDK download.  Everything compiles ok, but when I try to use the FX3-->SPI_Flash option to program, I get an error from the following code.

                    StatLabel.Text = "Programming of SPI FLASH in Progress...";

                    Refresh();

                    enmResult = Fx3.DownloadFw(FOpenDialog.FileName, FX3_FWDWNLOAD_MEDIA_TYPE.SPIFLASH);

                    StatLabel.Text = "Programming of SPI FLASH " + Fx3.GetFwErrorString(enmResult);

                    Refresh();

The returned error is SPILASH_ERASE_FAILED

This error doesn't occur in the binary utility included with the SDK.

Using a USB analyzer, I can see that the same command  C4H,1,0,0 is sent from both applications, but in my compiled version, it fails and in the utility (compiled by Cypress) the same command succeeds.

Any direction on this would be helpful.

Thanks

J.

Hi,

This is not expected to happen. The compiled version was Debug or Release? Can you please try with either of these and see if it is working in any of these?

I have tried debug and release with no success.    I am using VS 2013 Update 5

Microsoft Visual Studio Premium 2013

Version 12.0.40629.00 Update 5

Microsoft .NET Framework

Version 4.6.01055

Is there a way for me to send you my build to look at?

I need to write a standalone boot loader for our project and this is stopping me from getting started.

Thanks for your help.

Hi,

I was hoping this had been resolved. I'm having almost exactly the same problem. (C++ instead of C#).

I can program the SPI flash from the Control Center, and it works just fine. However, making the call to DownloadFw() with SPIFLASH selected gives me the same 0x7 return code (failure to erase flash). It works fine if I download to RAM instead of flash.

Putting a scope on the lines to the flash, I see no activity when I call DownloadFw(). If I use the Control Center, I see lots of activity while it programs the flash.

I'm using the 1.3 version of the SDK.

Any chance there has been some progress?

Thanks
