Unable to read device chain (JTAG chain broken) If you don't have a development board, it will be displayed. Use the two below to correct these changes:Īt this time, it has been inserted into the development board. Ubuntu9.1 and later version of the kernel, USB FS is not used, so no longer exists /proc/bus/usbThis directory, unfortunately, Quartusii9.1 uses this directory to drive USB Blaster. Save is OK, this means that Idendor is 09fb and the idproduct is 6001, Mode is to be set to 666, and this USBBLASTER is quite convenient.Īt this point, the USB permission problem is completed, because the original author uses ubuntu14 + quartus12, you can use it directly, but for us, the problem is far from the end Correction of kernel changes Is very simple is to write our files in the default rule directory of /etc/udev/rules.d, write our files,Īnd the name can be arbitrarily, the first two numbers should be guaranteed to be larger than the previous existence, that is, this is the decision priority, However, because the 003 path is the system allocation, sometimes it is not this path, so if you don't go in, you can see if there is any change to another path, and then re-CHMOD.īut every time you need to change or trouble, the PC should serve the people instead of people for the PC service, so we use the UDEV setting rules to make each detected USB Blaster's device MODE to 666 ( RW-rw-rw-) Users who add writings other than the user group to write permissions

USB BLASTER configuration USB permission settingīecause the USB is only ROOT with ROOT, you can modify the permissions, the USB Blaster link is on the computer. The following is the step of running as a normal user rights: If needed As WIN, directly use the JTAG-SREVER, but also need to handle USB FS issues, but also set permissions. Since JTAG-Server defaults to RC.D should be run as a service with root permissions, there is no permission, and only need to have no USB FS processing for the new kernel, without re-modifying the default permission. Since Ubuntu is not in the officially supported system (at least quartus9.1 is like this), ubuntu14 is a long time later, that is, Linux's kernel It is necessary to change. Next is the problem that the old hard JTAG USB Blaster cannot recognize. Install it according to normal steps, and make the patch SP1 and SP2, basically smooth, here, here, the shell in the installation script is cshell, there is a command to find, change the CSH in the statement to TCSH Installation. The installation process is not smooth, recorded, as a backup of the big brain that is untrusive. It is exactly the dual system ubuntu14.04 64 bit.

The computer is installed in Win10, which is enough to install the file, I want to install Quartusii9.1, press M to style, the driver is definitely safe.
