On Windows hosts, Sourcery CodeBench Lite supports FlashPro devices used with Actel Cortex-M1 development kits.
For FlashPro devices, the device-url
has the following form:
flashpro:[//usb12345
/][?jtagclock=rate
]
The optional usb12345
part indicates
the ID of the FlashPro device to connect to, which is useful if
you have more than one such device attached to your computer.
If the ID is omitted, the Debug Sprite connects automatically to
the first detected FlashPro device.
You can enumerate the connected FlashPro devices by invoking the
Sprite with the -i
switch, as follows:
> arm-none-eabi-sprite -i flashpro:
The jtagclock
option allows the communication
speed with the target board to be altered. The
rate
is specified in Hz and may range between
93750 and 4000000.
The default is 93750, the slowest speed supported by the FlashPro device.
Depending on your target board, you may be able to increase this rate,
but beware that communication errors may occur above a certain threshold.
If you encounter communication errors with a higher-than-default speed
selected, try reducing the speed.
Windows drivers for the FlashPro device are included with the FlashPro software provided by Actel. Refer to Actel's documentation for details on installing this software. You must use the Actel FlashPro software to configure the FPGA on your Cortex-M1 board, but it does not need to be running when using the Debug Sprite.
Once you have set up your board using the FlashPro software, you can check that it is recognized by the Sourcery CodeBench Debug Sprite by running the following command:
> arm-none-eabi-sprite -i flashpro: [jtagclock=<n:93750-4000000>] FlashPro flashpro://usb12345/ - FlashPro Device ...
If output similar to the above does not appear, your FlashPro device is not working correctly. Contact CodeSourcery for further guidance in that case.
