Memory dumper for LPC21xx chips with unlocked boot loader. Dumps the contents of the internal flash memory via the In System Programming Interface by uploading a stub (dumper.c / dumper.hex) to the chip and running it.
To use, just connect the UART port of the LPC21xx to a USB UART adapter.
Enter the In System Programming mode as described in the manual (UM10114 chapter 21.5):
A LOW level after reset at the P0.14 pin is considered as an external hardware request to start the ISP command handler.
Then run the upload.py script from this repository.
usage: python3 upload.py [-h] [-p PORT] [-b BAUD] [-o OUTPUT] [-x HEXFILE] [--trace]
Upload dumper file to LPC21xx
optional arguments:
-h, --help show this help message and exit
-p PORT, --port PORT
-b BAUD, --baud BAUD
-o OUTPUT, --output OUTPUT
-x HEXFILE, --hexfile HEXFILE

The OUTPUT file will contain a iHEX dump with probably some trash data surrounding it.
