# This configuration is intended to be applicable to all of C11x, C12x, # C139 and C140. The "plain" version of compalstage selected below # should work for all C11x/12x; it will also work on C139/140 phones # that had the simpler boot code flashed into them, as we do with # FreeCalypso fw on these phones. When running loadtools with this config # on C139/140 phones that still have the official fw in them, one will need # to specify -h compal -c 1004 to use the inefficient ~15 KiB version of # compalstage. compal-stage plain # Whether we are breaking in through compalstage (as above) or through # tfc139, the re-enabled Calypso boot ROM is used to load our loadagent # into IRAM. The boot ROM will autodetect the Calypso input clock as # 26 MHz (physical reality) when entered through compalstage, or as # 13 MHz when entered through tfc139 - the latter results from the # original fw setting bit 7 in the FFFF:FD02 register (VTCXO_DIV2), # which the boot ROM does not clear. # # However, the following configuration will result in the ARM core # being clocked at 52 MHz in both cases. pll-config 4/1 rhea-cntl 0x00 # The remaining settings are carried out via loadagent commands init-script compal.init # Flash can be 2 MiB or 4 MiB, will be autodetected, 4 MiB mapping used # mapped at 0x03000000 like on other targets, see updated compal.init script flash single-4M 0x03000000 boot-reflash-hack 0x820000 0x10000 # Perform a Iota poweroff when we are done exit-mode iota-off
