## DESCRIPTION

lpc21isp is an in-circuit programming (ISP) tool for the NXP(Philips) LPC1100/LPC1300/LPC1700/LPC2000 series ARM7/Cortex-M0/Cortex-M3 microcontrollers.

## 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 (PHILIPSARM 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)

- **-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)

- **-ADARM**

  for downloading to an Analog Devices ARM microcontroller ADUC70xx

- **-PHILIPSARM**

  for downloading to a microcontroller from NXP(Philips) LPC13xx/LPC17xx/LPC2000 family (default)
