Michael Jung	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
Gregory Nutt	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
Heesub Shin	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.
