The defualt in NuttX is OSPEED of 50Mhz. This is realy a slew
rate control. At the default high slew rate the overshoot was
.7 Volts. On a ICM20649 this was causing the device to output
garbage. All 0s
N.B. A passive scope or Logic analyser's probes load will mask
the failure. Useed a FET probe to verify the issue.
Durandal:Fix PLL settings
durandal-v1:Move I2C123, I2C4 to HSI.
Not liking using HSI but, F7 has, and in reality there is no
requerment for accuracy.
durandal-v1:board config set 400kHz on card probe
durandal-v1:Board SDMMC Clock Not greater then 25 mHz
durandal-v1:Fix PLL3 configuration typo and value
CI build config for holybro_durandal-v1
durandal-v1:Kconfig - add knob to ensure ARCH_MATH_H is kept
Upstream changes added ARCH_HAVE_MATH_H to protect from archs
without math.h from causing isses for users setting
CONFIG_ARCH_MATH_H and getting errors. PX4 provides a math.h
and we need CONFIG_ARCH_MATH_H set. So this Selects
ARCH_HAVE_MATH_H perserving CONFIG_ARCH_MATH_H a defconfig
Track master LED removal
durandal-v1: bmi055 -> bmi088
bmi088 is what the board uses
durandal-v1:add PX4IO support
durandal-v1 rc.board_sensors: start baro
durandal-v1: remove segway module
durandal:Run at 480 Mhz
durandal-v1: build thermal control module
durandal-v1: enable IMU thermal control by default
durandal-v1:Track upstream adc start moved to rc.board_sensors
durandal-v1:Track upstream mavlink start moved to rc.board_mavlink
In the stm32f7 the configuration variable for SD card with DMA changed from CONFIG_STM32_SDIO_DMA to CONFIG_STM32F7_SDMMC_DMA
the maximum clock speed of 16MHz can now be achieved.
