NOTE: After the module reboots with the new firmware, it is recommended to reset the module to
factory default parameters using the factory R command. Failure to do so may result in some
variables being initialized with random values.
The previous firmware will become the backup image. Here is an example of what you should see after a
successful update:
FL# SIZ FLAGS
11 18 3 WiFly_GSX-2.20
29 1 10 config
30 18 3 WiFly_GSX-2.21
208 Free, Boot=30, Backup=11
The firmware checks the image (and compare to the stored values in the file) before committing it to flash
and updating the boot record after download. If the checksum fails firmware prints “UPDATE FAILED=x”
and deletes the image.
Note the module must be rebooted or power cycled to use the new firmware. To boot a different firmware
use the following command:
boot image <num> sets the current boot image <num>
For example to boot the previous image from above use
<2.20> boot image 11
Set Boot Image 11, =OK
