this adds a chibios_flags.h which contains the flags we pass to the
ChibiOS make, which allows us to have a make level dependency on the
flags
this fixes (among other things) the build of copter followed by
bootloader for SPRacingH7
this implements FATFS memory allocation in the HAL_ChibiOS malloc.c
which fixes mkdir() after a format of the microSD
The strategy is to deny large allocations and try for DMA allocations
if possible. This both fixes mkdir() and makes filesystem operations
faster as we have less copying of memory via the bouncebuffer
these are causing some boards to crash on startup. Tested with a
QiotekZealotH743 which doesn't get out of setup_usb_strings()
once we have debugged this we can re-add the functionality
this affects boards that share sdcard on the same bus as another SPI
device. In this case it was a QiotekZealotH743 where logging stopped
this issue is that the SPI hooks for MMC SPI did not do a DMA channel
lock before the SPI device lock. So when the RAMTRON driver on the
QiotekZealotH743 which is on the same SPI2 bus as the sdcard did an
operation we had a lock order violation
use regular ChibiOS RAM areas for RAM functions
exclude board.o from RAM functions and add some comments
use separate linker script for H750
use correct RAM area for process stack on H750/H743
update EXCLUDE items to put __early_init in flash on H730 and H750
optimize H730 ramfunc usage
correct calculation of advanced timers
add support for linker script configuration in mcu config script
use linker script configuration for H750 and H730
add single OTG_HS support on H730 via OTG2
make sure complimentary channels get advanced timers
complemntary timers do not require advanced mode
allow custom clockspeeds of 550Mhz
correct debug pins on H730
support custom clockrate of 520Mhz on H730
correct H730 USB end point pins
restructure linker script for STM32H730
allow chibios_hwdef.py to set advanced timer on L431
don't define RAMFUNC on STM32H730
clock tree for STM32H730
create non-cacheable memory area for SDMMC DMA
don't look for RAM_MAP in bootloader with external flash
this was already done on many (most?) boards, and greatly reduces DMA
sharing which improves performance of UARTs. This changes the default
to no DMA on I2C
Added support for stm32l4+ processor
- Added scripts for hwdef generation
- Tested in custom hardware prototype (stm32l4r5vit6)
- Tested all peripherals and auto pilot modes.
convert RCOutput to new virtual timer interface
cope with SDC vs SDMMC
use new SPIv3 driver. Correct clocks for SDMMCv2.
add STM32L431 support
port ChibiOS config to version 8
support SPIv3 driver model v2 on H7
use currcore in debug options
use new mmc API
disable speed optimizations in the bootloader to save a little flash
upgrade to halconf v8.4
relax constraints on QSP/flash clock.
add support for disabling QSPI reset in main firmware
this fixes an issue where a variable in SRAM1 gets set to a bad value
when we reset AHB1 with the top bit (a reserved bit)
the bug was only reproducible with this particular commit:
https://github.com/tridge/ardupilot/commits/cubeorangplus-crash-boot-bisect
but likely is just luck that it triggered on that commit. In this
instance it triggered as AP_OSD::singleton was reset to non-nullptr,
causing a panic() in AP_OSD::AP_OSD()
compiler was gcc 10.2-2020-q4
