ee9949a724 z20x: Fix some SPI/W25/Timer issues. 
arch/z80/src/ez80/ez80_spi.c:  Do not configure SPI chip select pin.  It is not used by the driver and configuring it just clobbers other usage of that pin.  Add some additional debug outputs; correct some exiting debug outputs.

drivers/mtd/w25.c:  Add some debug output.

boards/z80/ez80/z20x/src/ez80_w25.c:  Correct SPI bus number used in initialization.  Only SPI1 is supported.

arch/z80/src/ez80/ez80_timerisr.c:  Some initial timer configuration fixes.

6a3c2aded6 Fix wait loop and void cast (#24) 
* Simplify EINTR/ECANCEL error handling

1. Add semaphore uninterruptible wait function
2 .Replace semaphore wait loop with a single uninterruptible wait
3. Replace all sem_xxx to nxsem_xxx

* Unify the void cast usage

1. Remove void cast for function because many place ignore the returned value witout cast
2. Replace void cast for variable with UNUSED macro

a0e169ad7b net/: Fix a sixlowpan typo bug recently introduced; Rename g_ipv6_allzeroaddre with the more meaning g_ipv6_unspecaddr since the all-zero address is the IPv6 unspecified address (sometime IN6_ADDR_ANY). Remove more inline tests for IPv6 multicast with tcommint net_is_addr_mcast() macro. Update some comments. 2018-06-23 12:53:27 -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.

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'. Therefore wait for busy flag to clear in w25_readid() and w25_unprotect(). 2017-06-13 07:35:49 -06:00
