file.elf or
file.ihx
ao-usbload loads the specified .elf or .ihx file into the target device
flash memory via the AltOS boot loader, using either existing serial number
and radio calibration values or taking either of those from the command line.
- -T tty-device | --tty tty-device
- This selects which tty device the debugger uses to
communicate with the target device. The special name 'BITBANG' directs
ao-dbg to use the cp2103 connection, otherwise this should be a usb serial
port connected to a suitable cc1111 debug node.
- -D AltOS-device | --device AltOS-device
- Search for a connected device. This requires an argument of
one of the following forms:
- TeleMega:2
TeleMega
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.
- -s serial-number | --serial serial-number
- This programs the device serial number into the image. If
no serial number is specified, then the existing serial number, if any,
will be read from the device.
- -c radio-calibration | --cal radio-calibration This
programs the
- radio calibration value into the image for hardware which
doesn't have any eeprom storage for this value. If no calibration value is
specified, an existing calibration value will be used. The value here can
be computed given the current radio calibration value, the measured
frequency and the desired frequency:
- cal' = cal * (desired/measured)
- The default calibration value is 7119667.
ao-usbload reads the specified .elf file into memory, edits the image to
customize it using the specified serial number and radio calibration values.
It then connects to the debug dongle and writes the program to the target
device flash memory.
