The 286 pins have multiple functions. Many users accidentally enable both Ethernet and JTAG on shared pins. Fix: Always run pinout_check from the official diagnostic suite before wiring. soe286 mega

At 600 MHz continuous operation, the LGA package reaches 70°C. Fix: Attach a 15x15mm heatsink with thermal tape, especially if enclosed. At 600 MHz continuous operation, the LGA package
