[incubator-nuttx] 02/02: nucleo-wl55jc: add partition table support for progmem FLASH
This is an automated email from the ASF dual-hosted git repository.
xiaoxiang pushed a commit to branch master
in repository https://gitbox.apache.org/repos/asf/incubator-nuttx.git
commit 4d4566e9ed070e749ad27a5a24d7772b7c340116
Author: Michał Łyszczek <mi...@bofc.pl>

nucleo-wl55jc: add partition table support for progmem FLASH
This patch adds working integration of progmem FLASH. User can partition
internal FLASH memory to up to 4 partitions and use any combination of
raw, nxffs, smartfs and mtd_config filesystems (unless there are other
limitations like nxffs supports only single instance).
Support for dual CPU is added to Kconfig to not overwrite CPU2 program code.
Code guards user to not allocate more memory than there is on FLASH, and
warns user if not all FLASH memory is used. Errors will be printed when
user tries to initialize two instances of nxffs or mtd_config filesystems.
