NAME
ao-sky-flash - flash GPS firmware program to a SkyTraq GPS chip
SYNOPSIS
ao-sky-flash [-T tty-device] [--tty tty-device] [-D altos-device] [--device altos-device] [--loader boot-
loader] [--firmware gps-firmware] [--query] [--quiet] [--raw]
DESCRIPTION
ao-sky-flash loads the specified GPS firmware file into the target GPS chip flash memory using the
specified boot loader.
OPTIONS
-T tty-device | --tty tty-device
This selects which tty device the debugger uses to communicate with the target device.
-D AltOS-device | --device AltOS-device
Search for a connected device. This requires an argument of one of the following forms:
TeleMetrum:2
TeleMetrum
2
Leaving out the product name will cause the tool to select a suitable product, leaving out the
serial number will cause the tool to match one of the available devices.
--loader boot-loader
This specifies the desired boot loader to use for reflashing the device. You should use
srec_115200.bin unless you have a good reason not to. This should be in S record format.
--firmware gps-firmware
This specifies the new GPS firmware image to load onto the target GPS chip. No checking is done on
this device at all; flash garbage and the GPS chip will probably fail to boot.
--query
Instead of loading new firmware, query the current version of firmware running on the target
device.
--quiet
Normally, ao-spy-flash is quite chatty. This shuts it up, except for error messages.
--raw The expected target for reflashing is an Altus Metrum product with the GPS chip connected to the
CPU on that board and not directly to the USB serial port. This option says that the target GPS
chip is directly connected, which changes how things are initialized a bit.
USAGE
ao-sky-flash loads the specified bootloader into device RAM and then uses that to load new firmware to
flash.
