I set up a VPS, ocean1.zouck.org with a cross compiler-linker to compile programs, and a raspberry pi to program the resulting binary file into the chip thru a usb-serial BUB.
VPS Development Host
Build Tool Chain
On ocean1.zouck.org:sudo apt-get install build-essential gcc-arm-none-eabi
sudo apt-get install git
git config --global user.name "John Zouck"
git config --global user.email "jzouck@zouck.net"
Clone Test Code
From jeelabs git repository:
mkdir git
cd git
git clone https://github.com/jeelabs/embello.git
Build Binary (firmware.bin) for Downloading to LPC810
$ make firmware.bin

On Raspberry Pi
Download and build programmer "lpc21isp":
pi@raspberrypi2 ~ $ wget http://iweb.dl.sourceforge.net/project/lpc21isp/lpc21isp/1.97/lpc21isp_197.zip
pi@raspberrypi2 ~ $ mkdir arduino
pi@raspberrypi2 ~ $ cd arduino
pi@raspberrypi2 ~/arduino $ unzip ../lpc21isp_197.zip
pi@raspberrypi2 ~/arduino $ cd lpc21isp_197
pi@raspberrypi2 ~/arduino/lpc21isp_197 $ make
gcc -Wall -static -c -o adprog.o adprog.c
gcc -Wall -static -c -o lpcprog.o lpcprog.c
gcc -Wall -static -c -o lpcterm.o lpcterm.c
gcc -Wall -static -o lpc21isp lpc21isp.c adprog.o lpcprog.o lpcterm.o
pi@raspberrypi2 ~/arduino/lpc21isp_197 $
Download firmware.bin from ocean1:
sftp henry@ocean1.zouck.org
sftp> cd /home/henry/git/embello/explore/1446-lpc810/minimal
sftp> get firmware.bin
Fetching /home/henry/git/embello/explore/1446-lpc810/minimal/firmware.bin to firmware.bin
/home/henry/git/embello/explore/1446-lpc810/minimal/firmware.bin 100% 396 0.4KB/s 00:00
sftp> exit
pi@raspberrypi2 ~/arduino/lpc21isp_197 $ ls -l firmware.bin
-rwxr-xr-x 1 pi pi 396 Feb 16 00:18 firmware.bin
pi@raspberrypi2 ~/arduino/lpc21isp_197 $
Program chip using lpc21isp:
Connect BUB and 810 to raspi usb port and run:
pi@raspberrypi2 ~/arduino/lpc21isp_197 $ ./lpc21isp

Syntax: lpc21isp [Options] file[ file[ ...]] comport baudrate Oscillator_in_kHz
Example: lpc21isp test.hex com1 115200 14746
Options: -bin for uploading binary file
-hex for uploading file in intel hex format (default)
-term for starting terminal after upload
-termonly for starting terminal without an upload
-localecho for local echo in terminal
-detectonly detect only used LPC chiptype (NXPARM only)
-debug0 for no debug
-debug3 for progress info only
-debug5 for full debug
-donotstart do not start MCU after download
-try<n> try n times to synchronise
-wipe Erase entire device before upload
-control for controlling RS232 lines for easier booting
(Reset = DTR, EnableBootLoader = RTS)
-boothold hold EnableBootLoader asserted throughout sequence
-controlswap swap RS232 control lines
(Reset = RTS, EnableBootLoader = DTR)
-controlinv Invert state of RTS & DTR
(0=true/assert/set, 1=false/deassert/clear).
-verify Verify the data in Flash after every writes to
sector. To detect errors in writing to Flash ROM
-logfile for enabling logging of terminal output to lpc21isp.log
-halfduplex use halfduplex serial communication (i.e. with K-Line)
-writedelay Add delay after serial port writes (for compatibility)
-ADARM for downloading to an Analog Devices
ARM microcontroller ADUC70xx
-NXPARM for downloading to a chip of NXP LPC family (default)
