Cypress USB Support

Post by SDR-Radio.com » Mon Jun 22, 2015 11:39 am

Hi,

I am trying to compile the latest GitHub code with ENABLE_BACKEND_CYAPI enabled [x]. I've installed the Cypress SDK, but have problems in libbladerf_shared:

usb.obj : error LNK2001: unresolved external symbol _usb_driver_cypress

Maybe we can talk on SKYPE or you can give me a nudge via e-mail?

Toodles, Simon

We discussed this offline, so I just wanted to summarize here for other community members to see.

Between the Cypress FX3 SDK 1.3.1 and 1.3.3 releases, there are some API and directory layout changes that we still have to account for in our code and build script(s).

I've created Issue #399 regarding us needing to update.

The above tracker item provides the steps needed to downgrade from FX3 SDK 1.3.3 to 1.3.1, which is the current workaround.

Best regards,
Jon

Excellent support, working well with the Cypress drivers as well as LibUSB.
