OS Components</title><abstract><p>A device creator can replace data files and binaries in ROM by

means of eclipsing. A typical example for this requirement is to fix a software

issue. </p><p>To eclipse the files in the ROM, the device creators must add

a Stub SIS file to the ROM and install a package that supports eclipsing.

can be used again. </p> <p> <b>Note</b>: The installer does not allow two

different files to eclipse a file at the same time. For example, after eclipsing

a ROM file by installing a newer version of the file to <filepath>C</filepath> drive,

the installer does not allow you to eclipse the ROM file again by installing

another version of the file to <filepath>D</filepath> drive. The installation

fails. </p> <p> </p> </li>

<section id="GUID-124E78DC-2C94-4901-A90B-20DDC2F3AD66"><title>Important Considerations</title><p>Consider

the following tips to avoid common problems that can occur when eclipsing

ROM files. </p> <ul>

<li id="GUID-F3834539-10D0-518E-B004-EC512A4D73E7"><p>If you are eclipsing

an application <filepath>EXE</filepath>, make sure that both the application

and the eclipsing SIS file have put the application registration file (<filepath>*_reg.rsc</filepath>)

in <filepath>\private\10003a3f\import\apps\</filepath> rather than <filepath>\private\10003a3f\apps\</filepath>.

Else, the application framework picks up the application from <filepath>z</filepath> drive. </p> </li>

<li id="GUID-EE1F1535-D347-5DF8-8C36-935A48F3CFD2"><p>The <filepath>DLLs</filepath> and <filepath>EXEs</filepath> have

version numbers. You can set the version (which consists of a major and a

minor number) in the <filepath>MMP</filepath> file using the <codeph>VERSION</codeph> keyword.

The default version number is <codeph>10.0</codeph>. </p> <p>When eclipsing

a DLL available in ROM, the upgrading version number must be higher than the

one in ROM, otherwise, any EXEs in ROM (<filepath>Z</filepath> drive) that

link to this DLL can use the version on <filepath>Z</filepath> drive. However,

the new version must have the same major version number. </p> </li>

<li id="GUID-3D03C487-6303-5C49-B780-2489ADB637A1"><p>The application that

needs to be upgradable must not hard code any path to <filepath>Z</filepath> drive,

otherwise files are picked up from <filepath>z</filepath> drive. </p> </li>

<li id="GUID-8F3CACA0-5D68-505C-918F-8C0DADAB5577"><p>If you are upgrading

ECOM plugins on <filepath>Z</filepath> drive, you must increment the interface

implementation version number. </p> </li>

<li id="GUID-79CA5A58-A167-58E5-9C0B-21EAD8335FAB"><p>Verify that the vendor

names in the Stub SIS file match with the vendor names of the eclipsing SIS

file. </p> </li>

<li id="GUID-6530AAF8-AF5A-5D50-97D4-74117760816B"><p>In an XIP (execute in

place) ROM, the linking of executables to <filepath>DLL</filepath> s is done

at ROM build time. Therefore, to eclipse a <filepath>DLL</filepath> in an

XIP ROM, the <filepath>EXE</filepath> that uses it also needs to be eclipsed. </p> </li>

<li id="GUID-5213264C-0414-541F-B2B9-2DEC4AB85F91"><p>To eclipse language

specific files, it is recommended to eclipse every language variant that is

in the ROM. For example, if the application resource file has <filepath>.RSC</filepath> and <filepath>.R02</filepath> in

ROM, the eclipsing SIS file must also include <filepath>.RSC</filepath> and <filepath>.R02</filepath>. </p> </li>
