d93d129da6 cc2538: uart: Make it possible to use several UARTs simultaneously
This avoids the limitation of having a single UART available at runtime, without
duplicating code.

34e48f4233 Added bootloader backdoor configuration for cc2538DK in contiki-conf.h and selector in startup-gcc.c. Updated Makefile.cc2538dk to support direct uploading. Also updated the platform readme to include the workflow with cc2538-bsl. 2014-03-07 15:44:08 +01:00

a2686e581e cc2538: Add header file for flash CCA page and use it
Create a dedicated header file with all the definitions for the flash lock bit
page and customer configuration area. This avoids duplicating those definitions
in the startup-gcc.c files of all CC2538-based platforms, and this also allows
to easily manipulate the CCA from outside startup-gcc.c (e.g. for on-the-air
firmware update).

The definitions are now complete contrary to what was in startup-gcc.c:
 - Definitions have been added to select the bootloader backdoor pin and active
   level if enabled.
 - Definitions have been added to access the page and debug lock bits. The debug
   lock bit can be used to prevent someone from reading back a programmed
   firmware through JTAG if the firmware binary image has to be confidential,
   which should be combined with a disabled bootloader backdoor.
 - The application entry point is now tied to the beginning of the .text section
   instead of to the beginning of the flash. This allows projects using custom
   linker scripts to place the application entry point anywhere in the flash,
   which can be useful e.g. for on-the-air firmware update.

65806f53eb cc2538dk: startup-gcc: Do not redefine SYS_CTRL_EMUOVR
SYS_CTRL_EMUOVR is already defined in sys-ctrl.h, so #include this header file
instead of redefining SYS_CTRL_EMUOVR in startup-gcc.c.

6c6013b898 Make the CC2538 UART driver more configurable
* We can now very easily switch between UART0 and UART1 through a define
* We can also configure the UART RX and TX port/pin through defines
