TMDSEVM6657: uPP Interface

Hi,

I am sorry, but there are no examples showing how to utilize the UPP interface. You should refer to the user guide: www.ti.com/.../spruhg9.pdf and create your own code, depending on your use case.

I have already gone through the upp Peripheral datasheet . and prepared some part of the code.
I am having issue regarding how to configure to work in polling method and also require info regarding window address memory location.

Hi,

If you are using Processor SDK RTOS 4.3.0.5 version, there is a register layer support on UPP in this folder:
C:\ti\pdk_c665x_2_0_9\packages\ti\csl\src\ip\upp\V0

But apart from that there are NO other example codes.

Hi
i could configure all the registers according to my requirement,
i need some more description on polling and isr method usage .

Thank You.

Hi,

I was able to dig some more information on the uPP. Didn't have the time to go through it all, but I think it may be what you need to proceed with your driver:
processors.wiki.ti.com/.../Introduction_to_uPP
www.ti.com/.../sprugj5b.pdf
processors.wiki.ti.com/.../BIOS_Driver

Hope this helps.

Require some IRS routines on tms320c6657

Those depend on your use case. You should be able to serve the interrupt depending on the event that generated it, which is described in the documents I provided (End of Window, End of Line, Underrun/Overflow, Internal Error, and DMA Programming Error).

hi,
I have configured all the registers in my code .
Icouldnt find the uPP Registers in the Registers list in ccs Project .
Is there any thing else to add to check the registers runtime.

Thank You

Bug in Document: spruhg9

hi,
i felt that there is a bug in the above document at page no 28 - 2.6 Initialization and Operation
line 10a - UPIES should be replaced with UPIER.
//////////////////////////////////
10
Watch for interrupt events. Reprogram the DMA as necessary (checking that the PEND bit in the
uPP DMA channel status register (UPxS2) is 0).
10a
If polling, check "UPIES". Reading a bit as 1 indicates the corresponding event has occurred.
Write the corresponding bit with 1 to clear.
10b
If using ISR, check "UPIES" inside the ISR. Stru
cture the ISR according to the pseudo-code in
Section 2.6.4
.////////////////////////////////////


Please correct me if i am wrong .

I think you're right. Check the pseudo-code in 2.6.4 Sample Interrupt Service Routine.

Best Regards,
Yordan

I have went through that routine but not clear about from where it should be get called .
We have bought the TMDSEVM6657LS for a project which mainly deals with uPP but unfortunately there is no much support on uPP drivers(non bios and bios) .

i request to Resolve my issue at the earliest.

thank you

need details of Interrupt flow in multicore dsp 6657

request to Resolve my issue at the earliest.
