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

Error
Number
-1 A general error occurred. Retry the download. If the failure
persists, it is most likely due to a hardware failure; the MC21XX
requires servicing.
-2 The user cancelled the download.
-7 An error occurred opening the source device (either USB or
SDMMC). Check source device connectivity and retry.
-8 An error occurred opening the destination device (either NAND,
RAM, Power Micro, or CPLD). Retry the download. If the failure
persists, it is most likely due to a hardware failure; the MC21XX
requires servicing.
-9 The source device (either USB or SDMMC) could not be read
from. Check source device connectivity and retry.
-10 The destination device (either NAND, RAM, Power Micro, IST,
Keyboard Controller or CPLD) could not be written to. Retry the
download. If the failure persists, it is most likely due to a hardware
failure; the MC21XX requires servicing.
-11 An error occurred during transmission from the source device
(either USB or SDMMC) and the checksum check failed. Check
source device connectivity and retry.
-12 A checksum, generated from reading back data that was written
to the destination device, was incorrect. An error during
transmission or a write error to the destination device could cause
this.
-14 There is no more heap space available for the download
procedure. Restart Bootloader and retry the download. If the
failure persists, contact service with details of what is being
downloaded.
-19 The file contains invalid data. Check that the file is suitable for
downloading on this terminal.
