LPC2478 Unlock with Ksuite Tools
LPC2478 unlock manual:
What is LPC2478?
NXP Semiconductors designed the LPC2478 microcontroller, powered by the ARM7TDMI-S core, to be a highly integrated microcontroller for a wide range of applications that require advanced communications and high quality graphic displays. The LPC2478 microcontroller has 512 kB of on-chip high-speed flash memory. This flash memory includes a special 128-bit wide memory interface and accelerator architecture that enables the CPU to execute sequential instructions from flash memory at the maximum 72 MHz system clock rate. This feature is available only on the LPC2000 ARM microcontroller family of products. The LPC2478, with real-time debug interfaces that include both JTAG and embedded trace, can execute both 32-bit ARM and 16-bit Thumb instructions.

Note: LED need to monitor the state of the processor and it must be switched by the controller. If you do not have the power on the controller when connected by USB, then connect the other power source.
To flash the LPC2478 via Jlink, the level of protection should be CRP0, ie protection should be disabled. If security levels CRP1 and CRP2 have the ability to erase and reflash LPC2478 via UART, eg via USB to UART TTL adapter ftdi232 or cp2102 and Flashmagic program.
