NAME

       ao-usbload - flash a program to an ARM-based AltOS device

SYNOPSIS

       ao-usbload  [-T  tty-device]  [--tty  tty-device] [-D altos-device] [--device altos-device] [--cal radio-
       calibration] [--serial erial-number] file.elf or file.ihx

DESCRIPTION

       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.

OPTIONS

       -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.

USAGE

       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.
