0f18e8cc32 Merged in ebsong/nuttx (pull request #722)
Pull request for mtd/progmem refactoring.

* mtd/progmem: change up_progmem_npages to up_progmem_neraseblocks

    page is a unit for read/write operation.
    eraseblock is a unit for erase operation.
    up_progmem_npages is a little bit confusing because it returns number of
    erase blocks in flash memory. This patch changes up_progmem_npages to
    up_progmem_neraseblocks. There is no logical change.

* mtd/progmem: up_progmem_erasesize.

    Change argument name to be more readable.

* mtd/progmem: up_progmem_eraseblock

    Change up_progmem_erasepage to up_progmem_eraseblock.
    eraseblock is more readable name than erasepage.

* mtd/progmem: change up_progmem_eraseblock's return value.

    up_progmem_eraseblock erase a block. so it's better to return the erase block
    size than page size.

121211f096 progmem interface: Discern r/w and erase page sizes. Introduce new up_progmem_erasesize architecture API to be able to communicate the read/write page size independently from erase page size. Implement up_progmem_erasesize for all architectures that already support progmem, assuming that for those architectures the sizes of both read/write and erase pages are identical. 2018-05-01 06:23:52 -06:00

f3b37e5da3 fs/procfs/fs_procfsprogrem: Add /proc/progmem. This is an alternative way to get the information that was previoulsy available in apps/system/free. apps/system/free was removed beause it made illegal calls into the OS violating the portable interface. This new procfs entry provides the same information with no such violation. 2017-11-13 09:08:39 -06:00

a10735b50d mtd/progmem: fix incorrect target address calculation
progmem_read/write() is incorrectly calculating the target address,
expecting the offset argument is given in a block number. This is
completely wrong and as a result invalid flash region is accessed.
Byte-oriented read/write interfaces of mtd device accept the
target address in a byte offset, not a block number.
