This directory holds NuttX board support for the TI LaunchXL-CC1310. This
|
|
board features the CC1310F128 part with 128Kb of FLASH and 20Kb of SRAM.

2019-01-21: Fragmentary board support in place. The initial intent
|
|
of this board support is simply to assist in the CC13x0 architecture
|
|
development. Serious board development will occur later. At present,
|
|
the CC13x0 does not even compile error-free: Compilation of cc14x0_rom.c
|
|
fails because the DDI0 OSC header file has not yet been ported.

|
Serial Console
|
|
==============
|
|
|
|
The on-board XDS110 Debugger provide a USB virtual serial console using
|
|
UART0 (PA0/U0RX and PA1/U0TX).
|
|
|
|
A J-Link debugger is used (see below), then the RXD/TXD jumper pins can
|
|
be used to support a serial console through appropriate TTL level adapater
|
|
(RS-232 or USB serial).

Using J-Link
|
|
============
|
|
|
|
Reference https://wiki.segger.com/CC1310_LaunchPad:
|
|
|
|
When shipped, the TI CC1310 LaunchPad evaluation board is configured to be
|
|
used with the on-board debug probe. In order to use it with J-Link, the
|
|
on-board debug probe needs to be isolated to make sure that it does not
|
|
drive the debug signals. This can be done by removing some jumpers next
|
|
to the XDS110 Out / CC1310 In connector [RXD, TXD, RST, TMS, TCK, TDO, TDI,
|
|
SWO]. After isolating the on-board probe, the CC130F128 device can be
|
|
debugged using J-Link. The J-Link needs to be connected to the board
|
|
using the micro JTAG connector marked "In".
|
|
|
|
I use the Olimex ARM-JTAG-20-10 to interface with the board:
|
|
https://www.olimex.com/Products/ARM/JTAG/ARM-JTAG-20-10/
|
|
|
|
NOTE: When connecting the J-Link GDB server, the interface must be set to
|
|
JTAG, not SWD as you might expect.
|
|
|
|
The RXD/TXD pins. PA0/U0RX and PA1/U0TX, can then support a Serial console
|
|
using the appropriate TTL adapter (TTL to RS-232 or TTL to USB serial).
