This can happen for example when a param type is changed from int32 to
float. The type check will then fail if the param is stored and the param
import will be aborted.
Now we just skip the entry and continue loading the rest.
This was only a problem when running as a task not on the work queue.
The problem was that init() opened the RC serial device, which was then
read in the main loop, which is a different context when run as a task.
Both PX4Test and Beat noted if only Brick to was connected
battery_status Intance 0 voltage was 0V for Brick2
The priority selection logic is run prior to the subscription
creation and only updated the priority on a change. Before the
subscriotions were created.
_battery_pub_intance0ndx is suposed track the location in
the _battery_pub array that is instance 0. It is then used
to associate (move) instance 0 with (to) the lowest brick
(highest priority in HW) brick that is selected in HW.
The Bug was that before the subscriptions are created,
_battery_pub_intance0ndx set to 1. And then and never updated.
The fix was to only run the priority selection logic once
the subscriptions are created.
BOARD_HAS_LTC44XX_VALIDS - 0 -> No LTC44xx IC, N is the number of
Power Bricks connected to the LTC44xx
For a LTC4417 this would be 2 as the
third prioriy is used for USB
BOARD_HAS_USB_VALID - If defied as 1 imples that infact
the USB has a priority connection
on the LTC44XX
BOARD_HAS_NBAT_V - the number of battery voltage sensing chennels
on the ADC
BOARD_HAS_NBAT_I - the number of battery current sensing chennels
on the ADC
A super simple (non FMUv5 compliant) board with no LTC44xx and just one battery
that have no current sense:
BOARD_HAS_LTC44XX_VALIDS = 0
BOARD_HAS_USB_VALID = 0
BOARD_HAS_NBAT_V = 1
BOARD_HAS_NBAT_0 = 0
A fully FMUv5 compliant design would use:
BOARD_HAS_LTC44XX_VALIDS = 2
BOARD_HAS_USB_VALID = 1
BOARD_HAS_NBAT_V = 2
BOARD_HAS_NBAT_0 = 2
These setting properly condition the ADC channles and all the Power
module valid sensing logic in the ADC module.
voltage3V3_v - the sensor 3.3V voltage rail
v3v3_valid - the value of voltage3V3_v may be 0. This
field is a 1 when the HW provides voltage3V3_v
brick_valid - is now a bit mask. A 1 in the postion inticate the
Power controler HW has a valid supply voltage
present (in V window) on that priority
(channel V1..Vn).
The mapping is formed by 1<<battery_status.msg.priority
or using the manifest constanst BRICKn_VALID_MASK
usb_vaild - is now indicated from the Power controler HW or
the usb_connected if Power controler is
not present.
brick_valid == 0 and usb_vaild = 1 implies the FMU is powered
from USB only
brick_valid != 0 and usb_vaild = 1 implies the FMU is powered
from the higest priority brick, providing a 1 bit in brick_valid
and from USB
This change implements the publishing of batery_status messages
for each brick on the system, using multi-pub.
Backward compatiblity is achived by always publishing the
batery_status of the bick that has been selected by the HW
Power Controller (PC) on instance 0.
The batery_status.system_source will be true in one and
only one batery_status publication when a valid bit is
set in system_power.brick_valid. However, if USB is connected,
and both brikcs are not providing voltages to the PC
that are in the Under/Over Voltage Window (set in HW)
the system_source may be false in all publications.
FMUv4Pro and FMUv5 Spec added multi brick support
FMUv5 added SCALED_VDD_3V3_SENSORS
This change provides legacy (FMUv2) defaults for Power Bricks and
Sensor rail volatage source.
system_source - This battery status is for the brick that is
supplying VDD_5V_IN
priority - Zero based, This battery status is for the brick
that is connected to the Power controller's
N-1 priority input. V1..VN. 0 would normally be
Brick1, 1 for Brick2 etc
Battery now assigns connected from the api in the
updateBatteryStatus, as well as system_source and priority
The PX4IO is an population option on some varients. To have
1) FMU only control
2) IO Only control
3) FMU fall back control
These pins need to come up as inputs, until the configuration
is determined.
Added comments to ADC defines with Pin numbers.
Added the GPIO_HW_{REV:VER}_DRIVE signals
Define the GPIO_nPOWER_IN_{A:C] and assign them to
BRICK1, BRICK2 and USB Valid.
Regroupped power signals and defined true logic Power Control macros
in the arch agnostic form.
Defined the same IOCTL defines for FMU GPIO IOCTL
Use the power Control macros on board_app_initialize
As done on fmuV4 on resets invoked from system (not boot) insure
we establish a low output state (discharge the pins) on PWM pins
before they become inputs as a result of the pending reset.
We also delay the reset by 400 MS to insure the 3.1 Ms pulse is
not too close to the last PWM pulse.
The LTC4417 provides a valid signals for brick1, brick 2 and USB
This change configures the GIOP and provides 1) a MACRO to read
the pin and 2) the IOCTL defines to read it from the FMU.
The macro's result is true logic: It is true when the signal is active.
(Active low on the the LTC4417). The IOCTL read would be the actual
pin state.
The V4 HW replaced the LTC4417 provided valid signal for USB.
with an active high, version. This commit configures the GIOP
and provides 1) a MACRO to read the pin and the IOCTL defines
to read it from the FMU. The macro result true logic: true
when the signal is high. The IOCTL read would be the actual
pin state.
The LTC4417 provides a valid signal for USB. This change
configures the GIOP and provides 1) True logic macro to

The macro will return true when the signal is active (low
