If your ULINK have a bootloader is automatically updated if connected in KEIL MDK. But if not have bootloader you must do it manually. - on the ULink there is a NXP LPC2148. This device has a serial bootloader in ROM. - download & install Flash Magic from http://www.flashmagictool.com/ - to activate the bootloader in the LPC you must short "P0.14/DCD1/EINT1/SDA1 (PIN 41)" to GROUND and power up. LOW on this pin while RESET is LOW forces on-chip boot loader to take over control of the part after reset. It may be has a two-pin jumper (J3) in the lower right under µC and USB Port. - at "J2" is the serial update port available, from left to right: RxD in, TxD out, GND. Connect to PC RS232. ***don't forget use a level converter RS232 to 3.3V. Like as MAX3232 - connect this port through a level shifter to RS232 Levels or a TTL-USB Converter to the PC - run the Flashmagic Software, select COM-Port, Controller and Target File and run the Update (sometimes the autobaudings hangs, cycle power and give him another try) Flash Magic Config Select Device = LPC2148 Com Port = COM x Baud Rate = 9600 Interface = ISP Oscillator (MHz) = 12
