aAdded support for the new 674x device. The 674x is floating point, binary code compatible, superset of the 64x+ device.
Added support for the 5505 device, including support for huge model which is supported by v3 of the 55x core.
Added examples for the dsk5505, evm6474, and evmOMAPL137.
Cleanup
of generated .cmd files to be compatible with new and legacy linkers
(5.1.x/28x, 4.2.x/55x, and 6.1.x/6x). The generated *cfg.cmd files have
been updated to use RUN_START/RUN_END syntax (instead of '.=') to
generate symbols where necessary. Prior to this change, there were some
comaptibility problems with old/new linkers for 28x and 55x. Note that
the 6.1.x linker will still generate a warning for 62x, 64x, and 67x
applications. This warning does not occur for 64x+, 67x+ or 674x
targets. Until this issue is resolved we recommend using 6.0.x tools
when using DSP/BIOS 5.33 for 62x, 64x, or 67x. This issue is tracked by
SDSCM00027852.

SDSCM00027067 add standard set of BIOS examples for evmOMAPL137, dsk5505, and evm6474
SDSCM00026279 DSP/BIOS 5.32 needs to support C674x targets
SDSCM00024645 DSP BIOS is still visible in Add/Remove Programs even after the uninstall of CCS has been completed
DSP/BIOS is binary compatible with DSP/BIOS 5.32 (and all the way
back to DSP/BIOS 5.21). Users do not need to recompile your source
files or libraries when updating to BIOS 5.33. However users *must*
rebuild their configuration since the generated linker .cmd file
(<prog>cfg.cmd) is different.
Solaris host is no longer supported in this release.
Customer-critical bug
fixes to earlier releases will be available to Solaris users if
required.
DSP/BIOS 5.33 does not support TMS320C54xx devices. Users of
such devices
should continue use DSP/BIOS 5.31.xx earlier releases. For
customer-critical
54xx-related issues, TI will continue to provide fixes to earlier
versions when
needed.
DSP/BIOS 5.33 no longer contains RTDX examples.
DSP/BIOS 5.33 does
continue to provide the RTDX libraries so existing applications using
RTDX will
continue to build and execute without any issues. To obtain RTDX
examples,
users should download the RTDX 2.0 release from:
Compatibility keys are intentionally independent of Marketing
product
numbers and are intended to:
Enable tooling to
identify incompatibilities between components, and
Convey a level of
compatibility between different releases to set end user expectations.
Compatibility keys are composed of 3 comma-delimited numbers -
M,S,R -
where:
M = Major.
A difference in M indicates a break in compatibility.
S = Source.
A difference in S indicates source compability.
That is, the user's source doesn't require change, but does
require rebuilding.
R = Radix.
A difference in R indicates an introduction of new features, but
compatibility with previous interfaces has not broken. If libraries are
provided by the package, an application must re-link with the new
libraries, but not rebuild from source.
Davinci
1.x IDMA0 problem workaround -- A custom version of
the HWI dispatcher was created to work around an IDMA0/MMR
problem in rev 1.x DM644x devices (see SPRZ241 - "TMS320DM6446 Digital
Media System-on-chip Silicon Errata" for more information about this
errata). This errata is only present in Rev 1.x DM644x
devices and is not present on other 64x+ devices.
The
HWI dispatcher has been updated to poll the IDMA0 status register and
wait for IDMA0 transfer to complete before calling the actual
ISR. This will ensure that the ISR will not reference an MMR
register while the IDMA0 is active. This will also ensure
that an asynchronous task switch will not occur while the IDMA0 is
active. This may affect interrupt response time, but should
not be a problem in most applications since IDMA0 jobs are usually
fairly short. This workaround is only supported by the HWI
dispatcher (the
HWI_enter/exit macros do not contain the workaround).
A
hidden configuration parameter (bios.GBL.USEIDMA0DISPATCHER) is used to select
this alternate version of the dispatcher. This parameter has
default value 'true' for DM644x and DM42x configurations.
This parameter has default value 'false' for all other 64x+
configurations. The user can set this parameter to 'false' if
they do not want this workaround used in their Davinci applications
(e.g., if their application is not using IDMA0 and/or they know that
that their ISRs do not reference MMR registers).
Memory
heap issue when updating existing configuration files --
Prior versions of the configuration tool allowed for an inconsistent
memory heap configuration. The tool allowed users
to enable heaps when no heaps were actually configured and the default
for bios.MEM.MALLOCSEG and bios.MEM.SEGZERO were still set to
'MEM_NULL'. This was causing problems in applications since
malloc() and MEM_alloc() were failing even when user thought they had
configured BIOS for dynamic memory allocation. The
configuration tool is now checking to make sure that configurations
that have heaps also have bios.MEM.MALLOCSEG and bios.MEM.SEGZERO set
to a valid heap. Update from existing projects might yield an
error message. The work around is to either remove the
'bios.enableMemoryHeaps(prog);' line from your configuration, or to add
a heap and set bios.MEM.MALLOCSEG and bios.MEM.SEGZERO
accordingly. See the
ti/bios/examples/common/evmDM6446_common.tci file (or others) for an
example of how to do this.
Gconf
uses wrong parameters when more than one pjt is opened and they share
the same .tcf file -- When
more than one CCS project
(.pjt file) share the same .tcf file, and two or more of the projects
are opened in CCS, opening a .tcf from one of the projects will launch
GConf using the DspBiosBuilder builder parameters defined for the most
recently opened project. This may result in incorrect base seed
properties and import file paths in the .tcf file being edited. To
workaround, do not share .tcf files between projects. This is tracked
by SDSCM00003834

RTA Control Panel does not update values correctly when using comma
decimal separator in Windows -- The RTA Control Panel

'.' is the decimal separator, or use default 1 second update
rate.This is tracked by SDSCM00017755.
HWI_isHwi()
documentation has
contradictory statement -- In
previous versions of DSP/BIOS, " calling HWI_isHWI() from main()
