h1. MT6260 Mediatek 2G capable CPU. h2. Memory Map RAM 0x40000000 LENGTH ? (based on some code searching, not tested yet) SRAM 0x70000000 LENGTH 0xcfff CONFIG_BASE at 0x80000000 CHIP_ID at 0x80000008 h2. Base-band Notes init sequence: - gpio - base-band serial interface - base-band parallel interface - auto power control - auto frequency control - download/upload - base-band front end - finite impulse response filter - auxiliary analog digital converter - chip settings - coefficients - turn power on research notes: Am looking at baseband init code that already exists: https://git.osmocom.org/osmocom-bb/tree/src/target/firmware/rf/mt6139.c https://git.osmocom.org/uboot-mt623x/tree/board/mtk/sciphone_g2/mt6140.c and correlating those with sources for 6260 and 6737. Also looking at 6235 data sheet which has rather complete information about baseband resources: http://read.pudn.com/downloads157/doc/comm/701374/MT6235%20GSM%20GPRS%20Baseband%20Processor_%20Data%20Sheet_1.02.pdf h2.
