From e4a40d257d6c8fa393929cda50c0a1d777787da2 Mon Sep 17 00:00:00 2001 From: Mariano Alvira Date: Sat, 27 Feb 2010 22:51:41 -0800 Subject: [PATCH] Add target/mc13224v.cfg The MC13224V is a FreeScale ARM7TDMI based IEEE802.15.4 platform for Zigbee and similar low-power wireless applications. Using PIP (Platform In Package) technology, it integrates: an RF balun and matching network; a buck converter (only an external inductor is necessary); 96KB of SRAM; and 128KB of non-volatile memory. It has an integrated bootloader and can boot from a variety of sources: external SPI or I2C non-volatile memory, an image loaded over UART1, or the internal non-volatile memory. The image loaded from one of these sources is executed directly from SRAM starting at location 0x00400000.
