Thu, 15 Mar 2007 13:36:44 +0000 (13:36 +0000)
- added support for reading IHEX files (through fileio)
- load/dump_binary renamed to the more generic load/dump_image <file> <address> ['bin'|'ihex']
- added NAND framework (preliminary)
- added support for the LPC3180 SLC and MLC NAND controllers (preliminary)
- fix initialization for parport
- gw16012 fixes/cleanups
- added EmbeddedICE version 7 (preliminary, reported on two LPC23xx devices so far)
- added 'arm7_9 etm <target#>' configuration command to enable access to the ETM registers
