# This loadtool target configuration is intended to be applicable to all
# original hardware designs created within the FreeCalypso project,
# starting with FCDEV3B.  Specifically, it should fit all targets that
# satisfy the following criteria:
#
# The DBB chip is Calypso C035
# The RF block is Rita (26 MHz VCXO)
# Spansion S71PL129NC0 used for flash and XRAM, copied from Pirelli DP-L10
# The 2nd flash chip select is wired to nCS2

# 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 cs2-4ws-8mb.init

# Flash global config and chip select base addresses
flash dual-8M 0x03000000 0x01800000

# Perform a Iota poweroff when we are done
exit-mode iota-off
