Common Errors

unable to open ftdi device

device not found

This error means that a HDMI2USB board in JTAG mode was not detected. Power cycle the board and make sure you have followed the 3) Configure your board section.

Warn : Adapter driver 'usb_blaster' did not declare which transports it allows; assuming legacy JTAG-only
Info : only one transport option; autoselect 'jtag'
Warn : incomplete ublast_vid_pid configuration
jtagspi_program
Info : usb blaster interface using libftdi
Error: unable to open ftdi device: device not found

inappropriate permissions on device

This error means that your user doesn't have permission to talk to the HDMI2USB board. This is normally caused by not installing the udev rules which come with HDMI2USB-mode-switch.

Warn : Adapter driver 'usb_blaster' did not declare which transports it allows; assuming legacy JTAG-only
Info : only one transport option; autoselect 'jtag'
Warn : incomplete ublast_vid_pid configuration

If you get an error like this;

It means the JTAG firmware on the FX2 has gotten confused. Use mode-switch tool to switch to serial mode and then back to the jtag mode like this;

hdmi2usb-mode-switch --mode=serial
hdmi2usb-mode-switch --mode=jtag

Load the firmware

make firmware-load

If you see no output, press ‘Enter’ a few times. You can then kick off the firmware loading process again:
