EZ USB FX2 DRIVER

Their Linux support builds on the common kernel and user mode USB infrastructure, which you can read about elsewhere on this site. Martin Diehl has provided EZ-USB firmware implementing simple device protocols that are very useful when used with usbtest software from Linux-USB hosts, to help verify correct operation of the host and isolate bugs. Someone could usefully write a Free Software version. Plugging EZ-USB devices into a Linux system runs device-specific scripts, which can download the appropriate firmware hexfile. Kernel device drivers can do the downloads, but then the firmware just locks down kernel memory. It can support all USB endpoints 30 plus control.

It can support all USB endpoints 30 plus control.

A number of them need to download firmware before they are usable. Plugging EZ-USB devices into a Linux system runs device-specific scripts, which can download the uxb firmware hexfile. Firmware source is available. The FX2 doesn’t support quite as many endpoints six plus controlbut it does handle multibuffered high speed transfers in hardware. One suitable loader is available from Cypress.

There’s a project f2x on HID firmware: Kernel device drivers can do the downloads, but then the firmware just locks down kernel memory. You could run simple tests that transferred control, bulk, or isochronous traffic.

USB devices typically have to work with many operating systems.

Their Linux support builds on the common kernel and user mode USB infrastructure, which you can read about elsewhere e this site. Device firmware just processes interrupts, fills buffers, and tells the hardware to do its thing.

This software is still usable on 2. The usbstress software http: A company called AnchorChips now owned by Cypress came out with an innovative and useful product a while ago: Someone could usefully write a Free Software version.

For in-the-field product updates, or for developers, you can use a specialized second stage loader to write the boot EEPROMs. This web page is designed as a community resource, with cross links to related projects as well as hosting some Linux-focused efforts directly.

The Linux system will typically be much more powerful, since it has at least a ysb processor and richer software environment.

When fxx2 directly by the Linux kernel, these devices appear just like any other kind of serial port. Martin Diehl has provided EZ-USB firmware implementing simple device protocols that are very useful when used with usbtest software from Linux-USB hosts, to help verify correct operation of the host and isolate bugs.

Devices that also have off-chip memory use the two stage loader mode.

Plus, it’s easier to distribute updated firmware if you don’t need to upgrade a kernel driver to do that. For end user scenarios, it hooks up easily to hotplug usbb.

At this writing, all that firmware is statically linked into the appropriate mini-driver. That means computers need to download firmware to such devices before they’re used.
