* arch/arm/include/efm32, src/efm32, and configs/efm32-gxxx-stk:
|
||||
The EFM32 Gecko Starter Kit port is now functional. At least
|
||||
NSH is running over LEUART0 on the board (2014-10-29).
|
||||
* arch/arm/src/sm34/sam_serial.c and Kconfig: Add support for SAM3/4
|
||||
basic TERMIOS and flow control. There are issues with IFLOW control:
|
||||
PDC or DMAC support is required (2014-10-29).
|
||||
* configs/sam4e-ek/src/sam4e-ek.h: Fix an error in a USART1 pin number
|
||||
(2014-10-29).

STATUS

======
|
||||
|
||||
2014-10-28. Testing is still in progress. At this point all basic boot
|
||||
operations are successful: The LEDs work and the application tasks appear
|
||||
to be successfully started. LED2 is on and LED0 is glowing (meaning that
|
||||
interrupts are being processed). However, I get no output on PE0. Data
|
||||
appears to be sent (at least by efm32_lowputc()). However, no signal
|
||||
activity is present on PE0.

(at least by efm32_lowputc()). However, no signal activity is present
|
||||
on PE0.
|
||||
|
||||
I am, of course, thinking that this is a pin configuration issue.
|
||||
2014-10-29: The NuttX is running on the EFM32 Gecko Starter Kit. There
|
||||
are not many peripherals to test in that configuration, but the NuttShell
|
||||
(NSH) is working over LEUART0 at 2400 baud (certainly that could go up
|
||||
to 4800. The documentation says that 9600 is also possible on the
|
||||
LEUART, but I am not sure how).
|
||||
|
||||
I originally planned to use UART0 at 115200 baud, but I never could get
|
||||
any output from the board. I reviewd my pin configuration and clocking
|
||||
carefully and the USART seems to think it is working correctly. So I
|
||||
am thinking that there is some board issue that prohibits that option
|
||||
(probably because UART0 is used with the board controller???). Pins
|
||||
are not available for other U[S]ARTs on the board.
|
||||
|
||||
2014-10-29: Calibrated the delays loops.
|
||||
|
||||
2014-10-29: The start-up time is long -- about a second. I have traced
|
||||
this to the default delay in bringing up the LFCLK in efm32_clockconfig.
|
||||
The default, reset setting of the LFXOTIMEOUT field of the CMU_CTRL
|
||||
register is 3 which corresponds to a delay of 32768 cycles, or a full
|
||||
second. I have not experimented to see if this delay can be reduced.
