OK. Will you at least be available to test libusbx' fxload with your platform? The obvious goal for spending time on this effort is, provided the FX3 becomes one of the leading USB 3.0 development target out there, to promote libusbx among developers who may only come for the FX firmware upload tool. But without a platform to validate against, this will be a bit of a challenge... Right now, I'm still spending/wasting time on eeprom flashing support for the FX2 (doesn't work for my board yet), but once that's sorted, I'll switch to adding FX3 support. > One thing that might changes necessary however is the new > firmware format that Cypress talks about in its FX3 API 1.2 > release notes: > > http://www.cypress.com/?docID=38763 <rant>Oh great, another company placing docs that should be publicly and anonymously accessible behind another fruitless registration wall.

"Added support in the firmware to jump back to the boot firmware image, without disconnecting the USB connection. This feature allows users to modify the application code without breaking the USB connection." I'd see the implementation above as an extension of the .IMG format rather than a brand new one. Probably something in the same vein as the 80 01 E6 00 00 reset block added at the end of the FX2's iic (fx2_trm.pdf chapter 3.4.3). > Still, right now it's still unclear how such a reset is going > to be initiated. I'll keep you updated. Thanks.
