Using OpenOCD to program the LPC1115 LPCXpresso board
|
||||
March 29, 2015 by acassis
|
||||
|
||||
Unfortunately NXP uses a built-in programmer in the LPCXpresso board
|
||||
called LPCLink that is not supported by OpenOCD and there is not (AFAIK)
|
||||
an option to replace its firmware.
|
||||
|
||||
Then I decided to cut the board to separate the “LPCXpresso LPC1115 REV A”
|
||||
from the LPCLink programmer.
|
||||
|
||||
So I used a simple and low cost STLink-v2 programmer board that is
|
||||
supported by OpenOCD. In order to use OpenOCD to reprogram the LPC1115
|
||||
board we need to connect four wires from STLink-v2 to LPC1115 board:
|
||||
|
||||
STLink-v2 | LPC1115 Board
|
||||
------------------------------
|
||||
GND GND
|
||||
3V3 3V3
|
||||
IO AD4
|
||||
CLK P0.10
|
||||
|
||||
|
||||
Also we need to instruct OpenOCD to use SWD protocol. You can do it
|
||||
creating the following config openocd.cfg file:
|
||||
|
||||
# LPC1115 LPCXpresso Target
|
||||
|
||||
# Using stlink as SWD programmer
|
||||
source [find interface/stlink-v2.cfg]
|
||||
|
||||
# SWD as transport
|
||||
transport select hla_swd
|
||||
|
||||
# Use LPC1115 target
|
||||
set WORKAREASIZE 0x4000
|
||||
source [find target/lpc11xx.cfg]
|
||||
|
||||
Now execute OpenOCD using the created config file:
|
||||
|
||||
$ sudo openocd -f openocd.cfg

|
||||
Verification will fail since checksum in image (0x00000000) to be written to flash is different from calculated vector checksum (0xefffebe9).
|
||||
To remove this warning modify build tools on developer PC to inject correct LPC vector checksum.

|
||||

|
||||
|
||||
The checksum warning message could be removed if you add the checksum to
|
||||
binary, read this post:

||||

||||

The blink LED sample I got from Frank Duignan’s page:
|
||||
|
||||
http://eleceng.dit.ie/frank/arm/BareMetalLPC1114/index.html
|
||||
|
||||
Edit Makefile and configure LIBSPEC to point out to the right path:
|
||||
|
||||
LIBSPEC=-L /usr/lib/gcc/arm-none-eabi/4.8/armv6-m
|
||||
|
||||
$ make
|
||||
|
||||
To generate the final binary I used objcopy:
|
||||
|
||||
$ arm-none-eabi-objcopy -O binary main.elf blink_lpc1115.bin

Using OpenOCD and gdb to debug my NuttX port to LPC11xx
|
||||
May 22, 2015 by acassis
|
||||
|
||||
I’m porting NuttX to LPC11xx (using the LPCXpresso LPC1115 board) and
|
||||
these are the steps I used to get OpenOCD and GDB working to debug my firmware:
|
||||
|
||||
The openocd.cfg to use with STLink-v2 SWD programmer:
|
||||
|
||||
# LPC1115 LPCXpresso Target
|
||||
|
||||
# Using stlink as SWD programmer
|
||||
source [find interface/stlink-v2.cfg]
|
||||
|
||||
# SWD as transport
|
||||
transport select hla_swd
|
||||
|
||||
# Use LPC1115 target
|
||||
set WORKAREASIZE 0x4000
|
||||
source [find target/lpc11xx.cfg]
|
||||
|
||||
You need to execute “reset halt” from OpenOCD telnet server to get
|
||||
“monitor reset halt” working on gdb:
|
||||
|
||||
$ telnet 127.0.0.1 4444Trying 127.0.0.1...
|
||||
Connected to 127.0.0.1.
|
||||
Escape character is '^]'.

||||

|
||||
|
||||

|
||||
|

Now execute the command arm-none-eabi-gdb (from Debian/Ubuntu package
