e1769b22f1 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

c9661ad5a7 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
Gregory Nutt
0aa7209765 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

Gregory Nutt
276cc44878 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
Gregory Nutt
4df0fbec04 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
Gregory Nutt
70be3bae16 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

7f5b88dbcd LPC17 Ethernet: Added option to use the kernel worker thread to do most of the workload with CONFIG_NET_WORKER_THREAD option in Kconfig. Eliminated a problem with PHY DP83848C : it doesn't need a specific initialization on mbed. Critical bufix: From time to time (after some hours) the Ethernet receiver would lose one receive interrupt and the IP stack never recover because there is no receive watchdog as the transmit watchdog. From Max 2014-07-24 16:39:18 -06:00
