Bringup status by subsystem

Subsystem basic status extended status notes
PMIC base OK voltages nominal, but on high side for CPU (1.35V) -- need PMIC DVFS driver to dial it back
PMIC advanced needs driver for further testing
debug console OK OK
SDHC3 (microSD boot) OK
SDHC3 power switch
DDR3 base OK functions at 1066 MT/s, 1 GB configured
DDR3 extended need to test multiple DIMM/mfg configs
I2C1 (SMB) OK can read out DDR3 I2C config using i2cdump
I2C2: OK can read out accelerometer, PMIC bits using i2cdump
I2C3: FAIL may be driver issue
reset button: FAIL reset button hangs system, doesn't cause reboot
USB hub 1 OK tested with thumb drive, needs performance testing
USB hub 2 OK ditto

Known issues

Hardware

  • Inrush current limiting for 3.3V_DELAYED turnon: R38N should be increased to about 30k. Need to verify with experiment turn-on timing margin (i.e. put smaller values in until failure to determine how much margin is available at 30k to ensure consistency across process variation)

Software

U-boot

  • DDR3: need to come up with alternate poke files for different SO-DIMM types
  • DDR3: need to figure out how to configure u-boot to recognize greater amounts of DRAM
  • MMC: USDHC3 has to have the CD check return 1 at all times. Patch not yet checked into trunk - todo bunnie

Linux

  • MMC: device tree novena.dts descriptor edited to note that USDHC3 port is non-removable in order to enable boot Patch not yet checked into trunk - todo bunnie
  • Power: Driver for power currently assumes fixed regulators, an incorrect assumption. This needs to be changed to use the PFUZE PMIC. Currently, no drivers exist in the source tree (based off of the sabrelite). Recommend using Sabre board for smart devices as the base image instead of sabrelite - todo xobs
  • USB/Power: PMIC does not turn on the USB VBUS by default, which causes internal root hub to fail. To fix this:
    • add i2c2 to device tree (added to novena.dts but not yet checked into trunk - todo bunnie)
    • run this command to turn on the boost regulator:
i2cset 1 0x08 0x66 0x48
  • once USB is on, I can verify/see USB drives in both USB ports. See this:
root@novena:~# lsusb 
Bus 002 Device 002: ID 05e3:0614 Genesys Logic, Inc. 
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 002 Device 007: ID 0b95:772b ASIX Electronics Corp. 
Bus 002 Device 004: ID 05e3:0614 Genesys Logic, Inc. 
Bus 002 Device 006: ID 058f:6387 Alcor Micro Corp. Transcend JetFlash Flash Drive
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  • ASIX driver module isn't built in current kconfig. Need to figure out how to turn that on. - todo bunnie
  • i2c bus 3 (/dev/i2c-2) seems to be mis-configured, can't see the utility EEPROM there. Needs debugging, maybe dts is wrong? - todo bunnie
