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. Plugging EZ-USB devices into a Linux system runs device-specific scripts, which can download the appropriate firmware hexfile. USB devices typically have to work with many operating systems. Kernel device drivers can do the downloads, but then the firmware just locks down kernel memory.

EZ USB on Linux

USB devices typically have to work with many operating systems. For in-the-field product updates, or for developers, you can use a specialized second stage loader to write the boot EEPROMs. For end user scenarios, it hooks up easily ctpress hotplug utilities.

Someone could usefully write a Free Software version. Kernel device drivers can do the downloads, but then the firmware just locks down kernel memory.

A number of them need to download firmware before they are usable. Their Linux support builds on the common kernel and user mode USB infrastructure, which you can read about elsewhere on this site.

Device firmware just processes interrupts, fills buffers, and tells the hardware to do its thing. Firmware source is available. The Linux system will typically be much more powerful, since it has at least a bit processor and richer software environment.

Plugging EZ-USB devices into a Linux system runs device-specific scripts, which can download the appropriate firmware hexfile. Plus, it’s easier to distribute updated firmware if you don’t need to upgrade a kernel driver to do that. This software is still usable on 2.

Cypress EZ-USB FX2 – LinuxTVWiki

A company called AnchorChips now owned by Cypress came out with an innovative and useful product a uzb ago: 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.

The usbstress software http: One suitable loader is available from Cypress. That means computers need to download firmware to such devices before they’re used. The FX2 doesn’t support quite as many endpoints six plus controlusbb it does handle multibuffered high speed transfers in hardware.

When supported directly by the Linux kernel, these devices appear just like any other kind of serial port. You could run simple tests that transferred control, bulk, or isochronous traffic. At this writing, all that firmware is statically linked into the appropriate mini-driver.

There’s a project working on HID firmware: This web page is designed as fx community resource, with cross links to related projects as well as hosting some Linux-focused efforts directly.

Devices that also have off-chip memory use the two stage loader mode. It can support all USB endpoints 30 plus control.
