- Hello Mike,
The UPP seems to be an optimal solution. However, It looks like configuring the UPP is a bit complex. I can see there is a tcDspUpp.cpp file in a core library and some usage of its methods in tcDspFpgaCameraLink.cpp.
My qu... - Hi everyone,
I need a sample FPGA code for UPP(Supported by Critical Link) with it's UCF file(including timing constraints).
Thanks in advance.

- Actually,
I was going to suggest transferring to IRAM, or if you need to transfer to DDR, doing a chained transfer:
EMIFA -> IRAM, then IRAM->DDR
Sounds like you've seen improvement in moving into the IRAM. Unfortunately, our Q... - RK 04:53 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP- EDMA Transmission problem

Is there any way to change the EDMA3 configuration to reduce transfer time ? I want to transfer the data from FPGA's 16-bit EMIFA bus to IRAM, where I think the memory bus is 32-bit. For now I am using the unchanged ...

Do you guys have any example on how to handle a interrupt? I have it set up in Qsys, where I have a FIFO sending its interrupt signal to the HPS. But how do I handle it on the software side.
I read that I need device tree to se... - RK 03:16 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DSP- EDMA Transmission problem
- Solved !
You can use the IRAM section. It is disabled as cache in the current configuration .tcf file.

You'll need to create a custom workorder as those tools aren't built into the demo filesystem they provide. You can start with a copy of the demo filesystem and add/remove packages that you want.

I was able to verify that they have the cryptsetup package which contains dm-crypt and luks tools.

- I think you also need to modify the devices.c.
Search for cpsw_salve_data. The phy_id needs to be assigned to the correct slave index.

Just so you know we updated the u-boot branch with timings for the DDR to run at 400Mhz up from 303Mhz.
