17.6 Rec709 Colorspace Issue on Alternate Inputs

17.6.1 Description

When using HDMI or SDI inputs in Rec709 colorspace, the output colors are not correct.
For example, the reference points are shifted, colors are

not saturated, or the white is tinged

with a little magenta.

17.6.2 Identification

No error in the logs.

17.6.3 Solution

Install firmware version

4.1.7 and SM version 6.0.15 or higher.


17.7 Filesystem Corruption

17.7.1 Description

The filesystem is corrupted. Symptoms include:

Arborescence is wrong and showing ??? instead of some files/directories.

The KDM or DLM folders in /data lose their symbolic link to /doremi/dlms and
/doremi/kdms and KDMs/DLMs are lost as a result.

17.7.2 Identification

When looking at \doremi\log\kern.log (or \doremi\log\kern.log.x if the issue occurred a while
before the report was taken), you may see these kinds of messages when this issue occurs:

IMS1000 kernel: EXT3-fs error (device md1): ext3_check_descriptors: Block bitmap for group
16 not in group (block 589824)!

IMS1000 kernel: EXT3-fs (md1): error:

group descriptors corrupted


Look at drmreport.txt file and sea

rch for “ls -laRi /data,” or simply run “ls -la /data” on the unit if

you can access it. When this issue occurs, dlms and kdms folders do not show their symbolic
link to /doremi/dlms and /doremi/kdms, or some folders are missing and showing ??? instead.
