Cloners successfully reverse-engineered the V9 because the LPC4322 did not have secure boot. Today, "J-Link V9 clones" flood eBay and AliExpress for $20–$40. They work, but they have severe limitations: If you are looking to develop features or

Usually locked in at an 8 MHz or 12 MHz crystal acting as the base clock for the chip's internal PLL. If you were to design a compatible debug

If you were to design a compatible debug probe from scratch (not a clone), here is the minimum viable schematic you would need:
