FIXME Please add the installation procedure here.

Unlike the Rocket 5AC Lite (AR9342 535 MHz, 64 MiB RAM), Rocket Prism 5AC Gen2 (XC) and Rocket 2AC Prism (2XC) use the 720 MHz QCA9558 platform with three radio interfaces and hardware AirPrism active band-pass filtering:

Model Board / SysID SoC & RAM / Flash Primary Data Radio (wifi0) Active RF Filter Aux Radios
Rocket Prism 5AC Gen2 XC / 0xe7f9 (0xe7e9) QCA9558 720 MHz, 128 MiB DDR2, 16 MiB NOR QCA9880 v2 (0777:e7f9, PCIe IRQ 75, 5 GHz 2×2) Dual-Stage AirPrism (SPI + GPIO 13..16 + IRQ 64 blanking) wifi1 (2.4 GHz mgmt WMAC, IRQ 2) + airview1 scanner + GPS
Rocket 2AC Prism 2XC / 0xe7f7 (0xe7f5) QCA9558 720 MHz, 128 MiB DDR2, 16 MiB NOR QCA9880 v2 + 2.4 GHz RF downconverter (256-QAM) 2.4 GHz AirPrism (>35.5 dB OOB rejection, IRQ 64 blanking) wifi1 (2.4 GHz mgmt WMAC) + airview1 scanner + GPS
  • 16 MiB SPI NOR Partition Map: mtd0 u-boot (256k), mtd1 u-boot-env (64k), mtd2 kernel (1024k), mtd3 rootfs (14720k), mtd4 cfg (256k), mtd5 EEPROM (64k @ 0xff0000 storing ART + AirPrism calibration tables).
  • Quiescing airview1 Scanner Spikes: Running ifconfig airview1 down (without sending SIGSTOP to ubntspecd) eliminates off-channel scan jitter (-36% p95 RTT) while keeping hardware watchdogs intact.
