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 4-1.

Table 4-1

Bootloader Errors

Error Text

Error

Number

Probable Cause

Unknown error -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.

Cancelled by user -2 The user cancelled the download.

Can't open the

source

-7 An error occurred opening the source device (either USB or

SDMMC). Check source device connectivity and retry.

Can't open the

destination

-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.

Can't read from the

source device

-9 The source device (either USB or SDMMC) could not be read

from. Check source device connectivity and retry.

Can't write to the

destination device

-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.

Transmission

checksum error

-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.

Readback

checksum error

-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.

There is no more

heap space

available

-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.

Invalid data in verify

file

-19 The file contains invalid data. Check that the file is suitable for

downloading on this terminal.
