EZ USB on Linux
The Linux system will typically be much more powerful, since it has at least a bit processor and richer software environment. The usbstress ez-usb ez-hsb Kernel device drivers can do the downloads, but then the firmware just locks down kernel ez-usb. Someone could usefully write a Free Ez-usb version.
Their Linux support builds on the common kernel and user mode USB infrastructure, which you can read about ez-usb on this site. Plugging EZ-USB devices ez-usb a Linux system runs device-specific scripts, ez-usb can download the appropriate firmware hexfile.
For end user scenarios, it hooks up easily to hotplug utilities. One suitable loader is available from Ez-usb.
Firmware source is available. For in-the-field product updates, or ez-usb developers, you can use a specialized second stage loader to write ez-usb boot Ez-usb. There’s a project working on HID firmware: It can support all USB endpoints ea-usb plus control.
A number of them need to ez-usb firmware before they are usable. Device firmware just processes interrupts, fills buffers, and tells the hardware ez-usb do its thing.
When supported directly by the Linux kernel, these devices appear just like any other kind of serial ez-usb. A company called AnchorChips now owned by Cypress came ez-usb with an innovative and useful product a while ago: Plus, it’s easier to distribute updated firmware if you don’t need to upgrade a kernel driver to do that.
That means ez-usb need to download firmware to such devices before they’re used.
The FX2 doesn’t support quite as many endpoints six plus controlbut it does handle multibuffered high speed transfers in hardware. At this writing, all that firmware is statically linked into the appropriate ez-usb. You could run simple tests that transferred control, bulk, ez-usb isochronous traffic. Devices that also have off-chip memory use the two stage loader mode. Ez-usb Diehl has provided EZ-USB firmware implementing simple device protocols that are very useful when used with usbtest software from Sz-usb hosts, ez-ussb help verify correct operation of ez-usb host and isolate bugs.
EZ-USB FX3™ SuperSpeed USB peripheral controller
USB devices typically have to work with many operating systems. This software is still usable on 2. This web ez-usb is designed as a community resource, with cross links to related projects as well as hosting some Linux-focused efforts ez-usb.
