Welcome to the betrusted-hardware wiki!

For lack of a better place, here is the DVT hardware validation tracker.

  • on power, no tuning, board 2_L as measured at battery - 595mW (wifi off), 626mW (wifi scanning)
  • standby, no tuning, board 2_L as measured at battery - 4.3mA @ 4.2V = 18mW (wifi off), 12mA @ 4.2V = 50mW (wifi scanning)
  • ship mode, no tuning, board 2_L as measured at battery - 0.07mA-0.03mA (50/50 duty) @ 4.2V. Probably gas gauge.
  • backlight (keyboard strand) - +134mA at 4.15V = 0.556 watts 100% brightness

Quick Test

  • SRAM: OK
  • SPINOR: OK
  • KEYBOARD: OK
  • TRNG_AVALANCHE: OK
  • TRNG_OSC: OK
  • I2C: OK
  • RTC: OK
  • RTC_ALARM: OK
  • AUDIO: OK; note: firmware unstable after soft-boots
  • SPEAKER: OK
  • VIBE: OK
  • JTAG_LOOP: Ok
  • MEMLCD: OK
  • COM: OK
  • REBOOT: OK
  • WIFI: OK
  • CHARGER: OK
  • GASGAUGE: OK
  • SLEEP_POWER: OK
  • SLEEP_WAKE: OK
  • KEYBOARD_WAKE_COMBO: OK - consider introducing 100k pull-downs on sense lines
  • SHIPMODE: OK - requires ECO
  • SRAM_SLEEP_RETENTION: OK
  • EC_SPI: OK
  • EC_UART: OK
  • SOC_JTAG: OK
  • SOC_UART: OK
  • GYRO: OK (but interrupts not tested)
  • BACKLIGHT: (kbd OK LCD pending)
  • USB_BOOST: FAIL - needs work-around PCB for switchover network
  • USB_DEVICE: OK - works as wishbone target
  • USB_HOST:
  • CHARGER_DETECT: OK
  • VBUS_LEVEL: OK
  • T_DISCHARGE: OK
  • ANTIGLITCH: OK
  • XADC: OK
  • BITSTREAM_INJECT: needs drivers, defer

Full test

  • All TBD
