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.
