Dear TriMeida group,

I am working with a TriMedia 1300.

In the file "tmIIC.c" I found the following code:

if (TM1100_1_2) {
       if ((byteCount > 1) && ((byteCount % 4) == 1))
               return (IIC_ERR_BAD_COUNT);

Because we have (very seldom)a problem writing to an other slave IIC
device in case we send exactly that amount of bytes, I would like to
know if that bug is absolutely fixed in the TM1300 chip.
Has any body else problems with the IIC cell in TM1300?

-Best regards, Götz-

Hi, everyone:

     I am designing the circuit board based on PNX1302. I meet some
problems when configing the SDRAM. The two SDRAM that i want to use
is 4Bank X 2M X 16bits as 32MB space. The MM_A[11] and MM_cs[1] are
connected to BA[0] and BA[1] in the data sheet. But it is not clear
that MM_A[11] is connected to BA[0] or BA[1]. I want somebody to
explain it clearly. I also want to know whether it is better to use
two 4Bank X 2M X 16bits SDRAM to firm 32MB space. If using this
configration, what is the address map of SDRAM?

     Thank you for your help!

Hi, every one:

     I want to design a stangalone board based on PNX1302. It has the
Web function. The net card used in it is RTL8139D(L). Does anyone
know how to connect the PNX1302 to RTL8139 with PCI interface?
     Thanks for your help!

hello all;

i meet with a problem when overlay a picture on video program
playing. the picture is the same picture and the overlay
configuration is also same. when it was overlayed on a NTSC video
program, there is no sparkle and waver with this picture, but if it
was overlayed on a PAL video program, there is much more sparkle and
waver with this picture. can you give me an answer about this
problem, the follow information is my link way.

Hi, all:
   could u give me some solutions to convert 444->422 with low cycles?

Hi,all:
    i want to overlay text using OL directly. but i wondered how to
deal with the edges between the text and the background. could u give
me some suggestions? thanks a lot

Use ICp to scale U and V data to generated 422 data from 444. Look up the manual
for ICP description and take
a look at the device library as well.

thanks for your help. but in my application, the ICP is used to
display VO sequence images. could u give me any other solutions?

Write a software filter (Low Pass filtering) and do scaling in software.
One simple method: averaging the samples in two adjacent lines; However the
quality will be poor with this
implementation.

as written in section 12.17, it does not matter.
table 12-10 gives the mapping, however this
is of very little use unless you start to put a
logic analyser on the SDRAM pins.

I found that my computer (windows2000) can't "wait" or "sleep"
after I installed the MDS TM1300 IREF BOARD, I wonder what leads to
this problem(the driver?) and  how to solve it . Thanks!

You don't mention the OS, and you don't mention the version of the TM software
system.
The only drivers that get installed are "tmman.sys" and "tmman32.dll."  Does the
problem go away if you remove them?

In the bug list for the TM 1300, the audio out unit list the following bug.

IssueID :  22992
Fix Plan :  n/a
Short Description :  AO may fail (get stuck) on ACK1 or ACK2



Description:

On read of AO_CTL, the TRANS_ENABLE may be read as 0 despite it is

set to 1. Since in the Interrupt Service Routine, a read is performed

before any ACK is done, it could happen that on the write back to

AO_CTL the TRANS_ENABLE gets cleared.

Probability for this to occur is very very very low, since it

has never been reported. It has been found by pounding every

microsecond for hours the AO_CTL register.



Impact:

Severe if hit, since AO gets stuck. However, as stated previously,

it has never occurred unless a stress test is applied.



Workaround:

Software knows if the AO is enabled and should always write back

a '1' to TRANS_ENABLE, if AO is active.



Does this bug state that the transmission must be active for an buffer 1 or
2 interrupt to be cleared.  I am have a problem where the transmission from
the audio out has been shut off but only after an interrupt was pending in
the Audio out.  I acknowledge the source of the interrupt but the interrupt
does not clear.

Any help on this matter would be much appreciated.

Thanks,

Bill Kozlowski

that's a different bug.  AO does need to be running to clear the interrupt

Hi,

   Thank you for your help.
   Do you agree with the config of SDRAM that I has
used? I want to get 32MB space only using two chips.
But the chip with 32bits width is hard to find. Can
you give me any other advice for this question?

Thank you, Chuck. I renamed "tmman.sys" and "tmman32.dll"  and
restarted the windows, the problem did go away. But could you tell me
how to solve the problem in another way? I mean, windows can "sleep"
or "wait" without removing the two files? Is it a bug?

Hi, group

There is an example vo in DVE-2, and there are three .o files in vo
directory.

How do I generate the .o files for my .Y,.U,.V data?

It sounds like a bug.  This is the first report I've had of it.  I never sleep
or wait on my desktop machines, and I never install TM in my laptop.  Can you
make a complete bug report?  What OS?  What version of TM drivers?

Thank you, Chuck. I renamed "tmman.sys" and "tmman32.dll"  and
restarted the windows, the problem did go away. But could you tell me
how to solve the problem in another way? I mean, windows can "sleep"
or "wait" without removing the two files? Is it a bug?

Hello group,

Is there anybody who knows a way to force a partial 64 byte buffer of Audio
In data to be written to SDRAM.  I have a stream of data which is coming to
the Audio In that I need to collect which is not a multiple of 64 bytes.  Is
there some way to get to the data which is sitting in the hardware buffer.

Thanks,

Bill Kozlowski

This sounds like tmman kernel driver does not respond to Power Management Kernel
API's. Usually requested by OS (PC) to all kernel drivers before going to Sleep.
This is not supported in tmman since it is mostly (always) used  on a
development machine or
test target machine.

It sounds like a bug.  This is the first report I've had of it.  I never sleep
or wait on my desktop machines, and I never install TM in my laptop.  Can you
make a complete bug report?  What OS?  What version of TM drivers?

Feed some more clocks into the input.  Otherwise its stuck in the HW buffer

You can put the data into a C array and then compile it.
Or you can make the process faster by putting the data into an assembly file. 
At some level, tmcc and its ilk will have to write out the.o

Hi, group

There is an example vo in DVE-2, and there are three .o files in vo
directory.

How do I generate the .o files for my .Y,.U,.V data?

Hi! frank,

Have u got the figure of how many fields are lost to sync for
different cameras with SAA7113. Also have u worked on
SAA7114 and SAA7115.

Cheers,
Raj

Hi all,
I am a newer for Trimedia.
I have the application developed by others.and I also have the source
code for L1 and L2 and my application.In L1 and L2 the others have
given the .mi file ,but the application no the .mi file so I want to
recompile the .mi file for my flash.but always given the error:"tmld
error   :   Unresolved symbol _main
tmld fatal   :   C:\TRIMEDIA\bin\tmld aborted due to errors".
I only can find the _main in sysinit.c,but I change the name of
main,for example: "main1".but the compile error not change.
The application provided by others is compiled on SDE1.1,But now I
only have the SDE2.1.
My questions is :
1,Is the error cause by the diffrency version of SDE?
2,Face to the error, what can I do? change something and try?
3,My make file write as following:"$(ROMIMAGE): Makefile.mi
	 @ echo "creating rom image $(ROMIMAGE)"
	 @$(CC) -DMMIO_BASE_ADDR=0xefe00000 \
	 $(LINK_OBJS) $(PSOS_OBJ) $(LIBRARIES) \
	 $(LDFLAGS) $(CFLAGS) -o $(ROMIMAGE)
	 $(LD) \
			 -mi -exec -start=_main   \
			 -bdownload=__clock_freq_init \
			 -tm_freq 120000000       \
			 -load=0x0,0x800000 "
is it right?
Thanks

The OS I used is win2000 professional , the TM version is TM1300
revision 1.2 and SDE 2.2 . I hope it is helpful .
Didn't anybody else who met the problem? What do you think about it?
