# isp-programmer
ISP Programmer for NXP Cortex-M Chips
Command-line tool for programming NXP microcontrollers via the UART ISP interface.
## Features
### Secure Write
To prevent bricking the chip during an interrupted write:
- The checksum in flash is first set to zero, forcing the chip to boot into ISP mode if power is lost.
- The image is then written from the topmost page down to the first page.
- The first sector (which contains the valid checksum) is written last.
This ensures that any failure during programming will leave the chip in ISP mode.
## Chip Families Supported:
+ LPC80x
+ LPC802
+ LPC804
+ LPC82x
+ LPC822
+ LPC824
+ LPC84x
+ LPC844
+ LPC845
### Untested, expected to work
+ LPC81x
+ LPC810
+ LPC811
+ LPC812
+ LPC83x
+ LPC832
+ LPC834
+ LPC86x
+ LPC865
Chips using UU-encoded protocols (e.g., LPC1700 family) are not supported.
Other NXP devices with 1 kB sectors *may* work if added to the `lpctools_parts.def` file.
The configuration file is identical to that used by the [lpctools project](http://git.techno-innov.fr/?p=lpctools).
## Installation
### From PyPI
```bash
pip install ispprogrammer
```
### From Source
```bash
git clone https://github.com/snhobbs/isp-programmer.git
cd isp-programmer
pip install .
```
> Default chip definitions are bundled. For custom chips, use the --config-file flag or copy your lpctools_parts.def to /etc/lpctools_parts.def.
## Usage
### Erase Entire Flash
```bash
ispprogrammer --device /dev/ttyUSB0 -b 9600 -crystal_frequency 12000 masserase
```
### Program Flash Image
```bash
ispprogrammer --device /dev/ttyUSB0 -b 9600 -crystal_frequency 12000 writeimage --imagein blinky804.hex
```
### Read Chip Info
```bash
ispprogrammer --device /dev/ttyUSB0 -b 9600 -crystal_frequency 12000 querychip
```
