Andrew Tridgell 01472aa795 AP_FlashStorage: added support for STM32F1xx 2019-08-27 10:29:56 +10:00
Andrew Tridgell d2c9db3f1f AP_FlashStorage: fixed build error with -O0 2019-05-15 15:33:48 +10:00
Andrew Tridgell 6e1e89bb70 AP_FlashStorage: fixed a corruption bug 
many thanks to @sh83 for tracking down this bug. When write_all() is
called with non-zero offset in init it ends up calling write with an
invalid offset, triggering a full reset

This fixes issue #10874

Andrew Tridgell 91e5f56242 AP_FlashStorage: fixed a race condition 
fixes #7670

thanks to night-ghost for the bug report

Peter Barker 2ed8118cda AP_FlashStorage: adjust example so it does not exit 2018-09-19 22:40:20 -07:00
Andrew Tridgell 985a319c42 AP_FlashStorage: fixed build of example on small memory boards 2018-07-11 10:07:38 +10:00

Andrew Tridgell 1513246040 AP_FlashStorage: fixed two bugs found by night-ghost 
this fixes two issues found by night-ghost. The first occurs if a 16
bit flash write is not atomic and only the first byte is written. Then
we could end up declaring the data invalid on reboot and erasing.

The second is a race in switching sectors. If power off occurs at the
wrong time we would trigger en erase on reboot.

Andrew Tridgell 3b5f66fd9f AP_FlashStorage: fixed size of flash storage 2018-01-15 11:46:02 +11:00
Andrew Tridgell 0bfbc4bf72 AP_FlashStorage: added re_initialise() API 2018-01-15 11:46:02 +11:00
Andrew Tridgell bfd137e36a AP_FlashStorage: added erase_ok callback 
this allows for simpler operation when application wants to allow
erase while disarmed.

Andrew Tridgell 0e00c3cf9b AP_FlashStorage: reduced sector size for example 
allows it to fit in SRAM on PX4

Andrew Tridgell fc21e0f16f AP_FlashStorage: a flash storage driver 
this will allow for a storage backend using flash sectors in a log
structure
