    • uxmhf-rpi3: revise instructions to configure existing üapps and add new üapps
    • uxmhf-rpi3: clarify OS kernel boot configuration details
    • uxmhf-rpi3: migrate documentation from markdown to restructured text syntax

  • Fixes

    • uxmhf: revise xmhf-bootloader sources to cope with --disable-drt and --disable-dmap configure options
    • uxmhf-rpi3: modify main.c to place uart_testrecv() inside a #ifdef to eliminate build errors if not configured for UART debugging
  • Build
