Title: USB Blaster III Compatibility
Post by: Antti Lukats on May 23, 2025, 01:44:17 PM
Hi

starting from Quartus 25.1 it is possible to use FT2232H based JTAG programmers, like our Arrow USB Programmer without the Arrow DLL installation, it is all included nativly with Quartus both for Windows as for Linux.

To enable the UB3 mode you need to modify the FTDI EEPROM contact for UB3 compatible VID/PID.

Note #1: when once programmed to UB3 mode FT_PROG can no longer access the EEPROM, so you can not change back. But there are Linux tools you can use to erase the EEPROM.

Mote #2: the activity LED on Arrow USB Programmer stops working in UB3 mode with the current PCB versions TEI0004-02. In next PCB revision we will change the LED to support UB3 mode.

Hi,

I guess you mean this: https://github.com/ArrowElectronics/Agilex-5/wiki/USB-Blaster-III

One question: can we upgrade the Arrow USB Programmer from CYC1000 and MAX1000 boards to USB Blaster III?

Thanks.
