a) software is currently under test. specially is a lot of updates under test on
channels supported by the tdx-system
b) in a number of cases, the system is halted with an error code stating "si-dma
error"
5.3 a problem report has been established on the "sti-dma error". the following actions
have been taken to eliminate the problem:
a) an eco, (no 808) has been released
this eco updates the sti-micro-f/w (ic's no: 1885 to 1893) fro rev.10 to rev.11.
the module is changed from rev. 3a to 3b.
this eco reduced the frequency of the "sti-dma" error a factor 10 (ten)
b) a reference system was dedicated troubleshooting of the problem
the h/w of this system was checked intesely. the result of this check was that no
hardware deficiencies were observed.
c) a new release of tdx-system-f/w is almost through test and will be released shortly.
this new release amongst other also includes some modifications, which eliminaes
identified potential sources of the sti-dma-error.
after release from development will this new release f/w be installed on the reference
system for further observations.
5.4 status today is that on no h/w-items have been observed qualified efects in relation
to the sti-dma problem. the new release of the tdx-f/w will be handled as eco's
for 3 modules: sti, tia, ltux-s.
6. the trouble shooting of the sti-dma failure is being monitored very closely to
ensure coordination of effords an availability and of the best qualified resources.
current status based on the camps sites in use for integration at cr is that the
sti-dma-error is the only pending malfunction problem, where the h/w design cannot
be totally out of suspicion.
