From the datasheet of the only OctaSPI flash we currently support
(http://www.mt-system.ru/sites/default/files/docs/Macronix/mx25lm51245g_3v_512mb_v0.01.pdf):
After program/erase command is issued, auto program/erase
algorithms which program/erase and verify the specified page
or sector/block locations will be executed. Program command is
executed on byte basis, or page (256 bytes) basis, or word basis.
Erase command is executed on sector (4K-byte), or block (64K-byte),
or whole chip basis.
So the minimum write size is one byte.
Prior to this PR, the minimum program size (QSPI_MIN_PROG_SIZE) of
QSPIFBlockDevice was 256 by default and 512 for some targets.
Those values were in fact page sizes, not program sizes.
Here's an explanation:
* Most QSPI flashes can be programmed to a granularity of a
single byte or a few bytes - no need to be a whole page.
This should be the value of QSPI_MIN_PROG_SIZE. Applications
need to align buffer sizes to this granularity when
programming QSPI flashes.
* Each sending of the underlying QSPI program signal requires
destination bytes to be located within the same page.
If a QSPIFBlockDevice::program() call crosses page boundaries,
this function breaks down the operation into multiple chunks,
so it's not a concern for the application.
So this PR changes the default program size to 1 (byte), and
for targets with a 4-byte (1-word) read size it overrides the
program size.
Note: No config is needed for the page size, as it comes from
the SFDP table parsed during initialisation.
- Added absolute path as cmake failed to find linker file from relative path
- Added the missing MBED_CONF_CRYPTOCELL310_PRESENT
- Added the dependency library to BLE Cordio stack
Promote MBED_TOOLCHAIN_FILE_USED to cache variable so
its previous state can be recalled when re-building. This
is because CMAKE_TOOLCHAIN_FILE is also a cache variable and its
value is set on first run when it has not been set.
nanostack border router is now owned by ISG and has been moved
out of ARMmbed and into their organisation. ISG will be
responsible for updating and testing this example going forward.
