839e206a4a Modify ADDRENV Kconfigs. Z180 does not need all of the virtual address settings that the ARM does 2014-08-24 12:54:37 -06:00

dde84a0a20 addrenv interface changes: up_addrenv_create() may need to create .text and .bss/.data separately because of differing access privileges (read/execute vs read/write). And, as a consequence, up_addrenv_vaddr() needs to be split into up_addrenv_vtext(0 and up_addrenv_vdata(). 2014-08-24 11:54:14 -06:00

52b3735310 Recent STM32 UART change: Wasn't that logic backward? Shouldn't that have been disable the USART if (1) we don't have than many USARTs OR (2) we don't have that particular USART -- not AND. 2014-08-22 16:16:23 -06:00

2bc16b2ba5 wdog.h does not contain any application interface, only internal OS interface. Further, it is non-standard. Move wdog.h from include/ to include/nuttx. For the same reason, move the description of the watchdog timer interfaces from the Users Guide to the Porting Guide. 2014-08-21 11:16:55 -06:00

96e1bf0ec2 NSH link management now works! The last fix was to the Ethernet drivers: They cannot disable clocking to the Ethernet blok on ifdown. Otherwise, we cannot communicate with the PHY 2014-08-17 17:54:46 -06:00
Gregory Nutt
754541a381 Change the way PHY interrupts work: disable automatically. Then we have to re-subscribe each time after the interrupt fires 2014-08-17 16:51:56 -06:00
