6455f60c60 Remove os_internal.h it has been replace by several new header files under sched/. There have been some sneak inclusion paths via os_internal.h, so expect a few compilation errors for some architectures 2014-08-08 18:39:28 -06:00

39183d37b8 Change all time conversions. Yech. New timer units in microseconds breaks all existing logic that used milliseconds in the conversions. Something likely got broken doing this, probably because I confused a MSEC2TICK conversion with a TICK2MSEC conversion. Also, the tickless OS no appears fully functional and passes the OS test on the simulator with no errors 2014-08-07 18:00:38 -06:00

8b2a8fceba Change CONFIG_MSEC_PER_TICK to CONFIG_USEC_PER_TICK. This gives more options for system timers in general, but more importantly, let's us realize higher resolution for the case of CONFIG_SCHED_TICKLESS=y -- of course, at the risk of some new interger overvflow problems 2014-08-07 13:42:47 -06:00

ffcc0b8da3 SAMA5: Changes needed for a clean SAMA5D3 build after all of the recent SAMA5D4 changes. 2014-07-31 11:09:56 -06:00

c0c4cda763 SAMA5 HSMCI: e-enable TX DMA and verify that DMA writes to the SD card are functional. They are so now TX DMA is re-enabled in the driver. This might affect the SAMA5D3 platforms where the TX DMA problem was found. The SAMA4D3 and 4 use the same HSMCI driver. Much has change since then and it is not surprising that DMA is now functional. However, the has not be re-verified on the SAMA5D3 which has a different DMA controller. 2014-07-30 11:20:06 -06:00

611ea42dbf SAMA5D HSMCI: Fix a problem on card insertion/removal callback handling. Interrupts were being disable so that the callbacks occurred with interrupts disabled. This resulted in loss of some interrupts and some not-so-good behaviors. The solution is to perform all callbacks on the work thread unconditionally (2014-7-29). 2014-07-30 10:19:41 -06:00

059812c872 SAMA5D HSMCI: Add method to do RX transfer without DMA. The 8-byte SCR transfer was failing silently with the DMA transfer, leaving the SD card in single bit mode 2014-07-29 21:13:28 -06:00
