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.
Installation
From PyPI
pip install ispprogrammer
From Source
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.
