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.

08c001196b drivers/: Remove all explicit use of 'hidden' macro _info. Code must never use this directly. Code must always use a debug macro such as info which is basic on _info but can be appropriately filtered. 2017-01-15 13:00:50 -06:00

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!

5b6fafb3f5 Several MTD FLASH drivers nullify the freed 'priv' structure and failed to return NULL as stated in the comments. Result, will operate on a NULL pointer later. Noted by David Sidrane. 2016-06-30 17:49:53 -06:00
