Peter Barker ecde9f8c3f AP_HAL_ChibiOS: make HAL_FLASH_PROTECTION a boolean, stop checking for definition 2022-08-16 08:10:16 +10:00
Andrew Tridgell 392e80001f HAL_ChibiOS: fixed H7 flash storage 
this fixes the flash re-init problem when flash storage fills on
H7. It was caused by rejecting writes where one or more of the 32 byte
chunks was not all 0xff but was equal to the current data. That
happens when writing to the sector header in AP_FlashStorage

it also moves the interrupt disable inside the loop to allow for
other interrupts to run between blocks

Andrew Tridgell a0c867bce7 HAL_ChibiOS: disable interrupts during flash operations 
we have now shown that interrupts being enabled during flash
operations can cause the infamous "68ms" bug, or watchdog when using a
32 bit timer on boards using flash for storage

The issue is quite repeatable with a load of a very large waypoint
file (over 500 waypoints) using "wp ftpload" in MAVProxy. This puts a
huge load on flash storage.

Our current working theory is that while doing flash writes for
storage on dual-bank we block access to only one bank, so if another
thread uses a timeout function with a short timeout while the flash
write is happening and chVTDoTickI calls code which crosses the flash
bank boundary then it can cause chVTDoTickI to violate the assumption
that no more than CH_CFG_ST_DELTA ticks pass while it is calculating
the value to set in the system timer. In that case we get a delay of a
full timer wrap, which is 68ms on boards with 16 bit timer and 70
minutes on boards with 32 bit timer

Andrew Tridgell b4201436dd HAL_ChibiOS: fixed flash space on 16k bl boards 
this avoids the stm32_flash_recent_erase() function which added around
800 bytes to the bootloader. It is not needed
