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.
