Bootloader Error Detection
While receiving data, Bootloader performs many checks on the data to ensure that the data is received
correctly. If an error is detected, Bootloader immediately aborts the download, and reports the error on an error
screen.
This error message screen displays until a key is pressed. Once the screen is acknowledged, Bootloader
returns to the main menu to wait for a new selection.
To find the probable cause of the error, use the error number and/or the error text displayed on the screen to
look up the error in
Table 7-1
.
NOTE
If an invalid image is selected, the LEDs blink three times.
