Bootloader Error Codes for Multi-Segment-LED DHCTs
4024836 Rev D
143
Er.27
Image overflow. The image is too large to fit into the area reserved for that image
type. This is typically caused by choosing the wrong image type ("s" option):
0 = OS/SARA (60 MB)
1 = Monitor (1 MB)
2 = DIAG (3 MB)
3 = OS/SARA (60 MB)
Change the "s" option and try again.
Er.30
Image length wrong. Displayed by the disk-based bootloader when the image
length specified in the signature block is different from the real length of the
received image.
Er.31
Invalid CRC. Displayed by the disk-based bootloader when the CRC in the
signature block cannot be verified.
Er.32
Incoherent signature. Displayed by the disk-based bootloader when the offset to
code start is outside the image, or when other signature values are incorrect.
Er.33
Expanded image CRC error. Displayed by the disk-based bootloader when a
compressed image is expanded and its CRC cannot be verified.
Er.34
Expansion overrun. Displayed by the disk-based bootloader when the expanded
image overflows available memory.
Er.35
Expansion stop-code failure. Displayed by the disk-based bootloader if the stop-
code was not found at the end of the compressed image during expansion.
Er.3F
Bootloader replacement error. Displayed by the upgradable, RAM-based
bootloaders when the new image is too large, or when the CRC is incorrect.
Er.41
Bootloader tuner communication error.
Er.45
TUA6130 detection error. The DHCT's NVM HwChipVersion indicates the
presence of a TUA6130 tuner, but it was not found.
Er.50
Disk not detected. The DHCT is supposed to have a disk drive, but it did not
respond during DHCT initialization. Displayed by the disk-based bootloader.
Er.51
Disk not responding. The disk drive was found during initialization, but it is not
responding to commands. Displayed by the disk-based bootloader.
Er.52
Disk timeout. The disk drive did not finish the commanded operation in the
allotted time period.
Er.53
Error reported from disk. Operation finished with an error reported by the disk
drive controller.
Er.54
DMA error during disk write. The DMA operation did not finish during the write
operation.
Er.55
DMA error during disk read. The DMA operation did not finish during the read
operation.
Er.56
Uncorrectable data errors have been reported from the disk drive.
