Migrating a MIPS BSP to 6.4.1

Applicable Environment

Topic: Migrating MIPS BSP
SDP: 6.4.1
Host: Any supported host

Recommendation

________________________________________________________________________

The MIPS ABI was changed in Momentics 6.4.1. Due to the incompatibilities between the old and new ABI's, the version of the runtime linker was incremented. Binaries built in Momentics 6.4.1 will now require ldqnx.so.3.

NOTE: This change only affects MIPS. All other architectures continue to use ldqnx.so.2.

If you are using a BSP released prior to Momentics 6.4.1, you may need to make the following modification to your build script:

- procmgr_symlink ../../proc/boot/libc.so.3 /usr/lib/ldqnx.so.2
+ procmgr_symlink ../../proc/boot/libc.so.3 /usr/lib/ldqnx.so.3

Attempting to use 6.4.1 binaries without ldqnx.so.3 present will result in output similar to this on boot:

Unable to start "devf-generic" (83)
