5ef548677a drivrs/mtd/filemtd.c: add block device MTD interface. Block MTD interface allows using block device directly as MTD instead of having to use file-system in between. NOTE that this provides the opposite capability of FTL which will let you use an MTD interface directly as a block device. 2017-10-19 09:53:41 -06:00

181875f3ba fs/vfs: Add new internal OS interface nx_read(). nx_read() is functionally equivalent to read() except that it does not modify the errno variable and it is not a cancellation point. Changed all references to read() in the OS to nx_read(). 2017-10-11 12:13:41 -06:00

a00d8e16a1 Adds OS internal function nx_write() which is functionally equivalent to write() except that it does not set the errno variable and do not cause cancellation points. 2017-10-11 10:18:30 -06:00

936df1bcb5 Adds new OS internal functions nxsig_sleep() and nxsig_usleep. These differ from the standard sleep() and usleep() in that (1) they don't cause cancellation points, and (2) don't set the errno variable (if applicable). All calls to sleep() and usleep() changed to calls to nxsig_sleep() and nxsig_usleep(). 
Squashed commit of the following:

    Change all calls to usleep() in the OS proper to calls to nxsig_usleep()

    sched/signal:  Add a new OS internal function nxsig_usleep() that is functionally equivalent to usleep() but does not cause a cancellaption point and does not modify the errno variable.

    sched/signal:  Add a new OS internal function nxsig_sleep() that is functionally equivalent to sleep() but does not cause a cancellaption point.

9568600ab1 Squashed commit of the following: 
This commit backs out most of commit b4747286b1.  That change was added because sem_wait() would sometimes cause cancellation points inappropriated.  But with these recent changes, nxsem_wait() is used instead and it is not a cancellation point.

    In the OS, all calls to sem_wait() changed to nxsem_wait().  nxsem_wait() does not return errors via errno so each place where nxsem_wait() is now called must not examine the errno variable.

    In all OS functions (not libraries), change sem_wait() to nxsem_wait().  This will prevent the OS from creating bogus cancellation points and from modifying the per-task errno variable.

    sched/semaphore:  Add the function nxsem_wait().  This is a new internal OS interface.  It is functionally equivalent to sem_wait() except that (1) it is not a cancellation point, and (2) it does not set the per-thread errno value on return.

sched/semaphore:  Add nxsem_post() which is identical to sem_post() except that it never modifies the errno variable.  Changed all references to sem_post in the OS to nxsem_post().

    sched/semaphore:  Add nxsem_destroy() which is identical to sem_destroy() except that it never modifies the errno variable.  Changed all references to sem_destroy() in the OS to nxsem_destroy().

    libc/semaphore and sched/semaphore:  Add nxsem_getprotocol() and nxsem_setprotocola which are identical to sem_getprotocol() and set_setprotocol() except that they never modifies the errno variable.  Changed all references to sem_setprotocol in the OS to nxsem_setprotocol().  sem_getprotocol() was not used in the OS

    sched/semaphore:  Rename all internal private functions from sem_xyz to nxsem_xyz.  The sem_ prefix is (will be) reserved only for the application semaphore interfaces.

    libc/semaphore:  Add nxsem_init() which is identical to sem_init() except that it never modifies the errno variable.  Changed all references to sem_init in the OS to nxsem_init().

    sched/semaphore:  Rename sem_tickwait() to nxsem_tickwait() so that it is clear this is an internal OS function.

    sched/semaphoate:  Rename sem_reset() to nxsem_reset() so that it is clear this is an internal OS function.

7b8df1b930 mtd/w25: wait for BUSY flag to clear in w25_readid and w25_unprotect. W25Q128 datasheet says that all instructions expect 'Read Status Register' and 'Erase/Program Suspend' are ignored when BUSY flag in status register is '1'.

2851959dee MTD M2PX: If we READ while a write/erase is pending, the command is ignored and the write/erase continues. If we dont catch this situation we will return garbage to the user because the flash will not execute the command. So READ MUST wait for write completion, and before that, the bus must be locked since it's a precondition to calling waitwritecomplete(). 2017-06-12 09:34:09 -06:00

0f7210b0ae mtd: fix some unallocated and NULL pointer issues. rwb->wrflush and rwb->wrmaxblocks in rwbuffer could get unallocated values from ftl_initialize() in some configurations. Also fixes related assert: 
up_assert: Assertion failed at file:rwbuffer.c line: 643

that can happen with the following configuration:

  CONFIG_FTL_WRITEBUFFER=y
  CONFIG_DRVR_WRITEBUFFER=y
  # CONFIG_FS_WRITABLE is not set

These problems are caused by CONFIG variable differences between the buffer layers. TODO: This is not a perfect solution. readahead support has similar issues.

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.

74777499bc alter the notion of 'blocksize' to be equivalent to 'flash write page size' in order to align with assumptions in the smartfs driver (at least, maybe other things do as well). 
Correct a bug that was previously masked by having blocksize=eraseblocksize which would cause buffer overflows and delicious hardfaults.

0d41a1cd42 Before accessing the sst26 flash, the "Global Unlock" command must me executed, which I do in the sst26 driver. 
BUT. re-reading the datasheet, the WREN instruction is required to enable the execution of this command. This was not done.

I have no idea how the driver currently works except by chance. The writes
should never happen at all, the flash is half-enabled!

af9590eef7 Extend the AT24Cxx MTD driver with support for -04,-08 and -16 parts. 
These parts utilize the same one-byte-address in the I2C protocol as the -02,
but requires different I2C addresses for different banks of the EEPROM.
