# Openmoko's GTA01/02 modem design is based on earlier Calypso phone or modem # designs by FIC, going back to 2004 according to dated comments in OM's FLUID # devices.txt file, and that parent design originally supported bigger flash # chips than the ones used in mass-produced GTA01/02 units. The latter have # Samsung K5A3240CTM or K5A3281CTM chips populated in them (4 MiB of flash, # 512 KiB or 1 MiB of RAM), but the PCB footprint actually fits a 16 MiB flash # chip (Spansion S71PL129J), with the second flash chip select wired to Calypso # nCS4. That devices.txt file also indicates that this nCS4 wiring was used # in FIC's 2004 design as well. # # This loadtool config is set up to address this maximum possibility of 16 MiB # of flash (in this particular wiring) or any subset thereof; it may be needed # if some early GTA01 prototype devices still had the bigger flash in them or # if someone finds an earlier (pre-Openmoko) FIC phone or modem. # The following parameters go into the <p command sent to the boot ROM pll-config 4/1 # 26 MHz in, PLL&DSP @ 104 MHz, ARM @ 52 MHz rhea-cntl 0x00 # good for all Calypso platforms # The remaining settings are carried out via loadagent commands init-script fic.init # Flash global config and chip select base addresses flash dual-8M 0x03000000 0x02800000 # Perform a Iota poweroff when we are done exit-mode iota-off
