Booting #RISCV Star64 #JH7110 SBC with Apache #NuttX RTOS ... So much faster now!

Windows will send every TFTP Packet 3 times ... Maybe that's why Star64 #JH7110 U-Boot won't work well with Linux TFTP Servers? 🤔

Star64 Power Adapter (3 Amp) failed with a loud pop ... So I switched to this Power Adapter: 12V, 3000mA, Centre positive, 5.5mm outer, 2.1mm inner (Same connector as Arduino Uno?)
