USB JTAG NT is the second generation of USBJTAG. The so called V2 of USB JTAG still uses USB 1.1 (12MHz specification, USB 2.0 480MHz). Due to clone product exist, the software development of USB JTAG has been stopped. New features will only be added to USBJTAG NT. Before you buy the USB JTAG from eBay, you need to investigate if he has the copyright and provide the software updates. (Google is good resource to use and see if there is any software update). UJmodem is a software based on USB JTAG NT and provide better UI as well as continue support C LI. USBJTAG NT provide faster programming speed and wider range of target support. The 48MHz of C PU clock and USB 2.0 specification makes the faster access of target possible. Most of the access speed is about 50% faster than USB JTAG. It supports PIC 32MX (EJTAG 2.6, with FASTDATA support it is even faster, the read memory goes to 450KB/s and write memory goes to 550KB/s). USBJTAG NT supports SPI flash making it the fastest SPI flash programmer in the world!! You can program MX25L0165A for only 8 seconds! UJModem video for program an SB5100 Program sigma UJModem video for modify the mac address C hange mac This is also the best tool for WRT54G router. Program the entire router under less than two minutes. Recent test has proved that is can 100% debrick any WRT54G router. USB JTAG NT supports PIC 32MX and program 512KB/s will take a little more than 3 seconds. The future plan is to support GDB for MIPS developer. PIC 32MX is the first to support and thanks the support from Microchip team. The GDB project is started and soon we will be able to debug PIC 32MX with USB JTAG NT.
