- RK 12:19 PM Software Development: RE: DSPLink library sources
- Thank you very much. That will do
Best regards - MW 12:01 PM Software Development: RE: DSPLink library sources
- All the dsplink source code should be in the 3rdparty folder of the BSP/MDK.
-Mike
- Hello,
I have a question. Is there any way I could access the source code of DSPLink libraries on DSP side ? Are there the files either on the TI sides in Critical Link's/ MDK ? What I am particularly interested in is the HWI interrupts...

- RK 06:31 PM Software Development: RE: DSP- EDMA Transmission problem
- Hello again,
Thank you very much for help. For the time being it looks like I will be able to make do with the tcDspUpp.cpp class.
Best regards, - I am not able to update opkg on MityDSP due to 404 error on angstrom-distribution.org. Where can I get the update?
- Hi, I am working with the MityDSP-L138-FI-236-RL target and could use some help to get our XDS510 debugger configured.
The XDS510 is enumerated OK on Windows. I used it before on a different project under CCS3.3
on the same laptop. ... - MW 06:30 AM Software Development: RE: spi1 usage in a custom board
- Hello,
Yes, for the 3.2 kernel provided, you need to create (or modify) a baseboard file as you have suggested. If you have a custom board, we recommend you copy the baseboard-industrialio.c file to a new file and modify it to repres... - EK 04:09 AM Software Development: RE: spi1 usage in a custom board

I do not want to modify uboot. It works good for me as it is.
I would like to configure our SPI using the linux kernel. As written in the previous post my custom board based on MityDSP138F has two ICs attac...

- JC 01:01 PM Software Development: RE: spi1 usage in a custom board
- If they only need to be configured on bootup it might be easier to do it from u-boot. You could try enabling the spi command: CONFIG_CMD_SPI. You could then test your spi commands and could put them as part of the bootcmd variable so t...
- Hi everybody.
I am a newby in Linux development. I have my custom board based on MityDSP138F with two ICs attached over SPI bus.
SPI signals (MISO, MOSI, and CLK) are attached to SPI1 bus. Chip Selects signal are attached to pins 53 ...

- JP 12:00 PM Software Development: RE: Net: No ETH PHY detected!!!
- I used the serial flashing program to erase the memory before flashing u-boot again and this time phy eth is detected and networking works normally.
I'm sorry for the trouble. - Hello,
I have a mitydspl138 board. I accidentally overwrote some of the u-boot memory. I used the serial programmer to re-flash u-boot

... - MW 07:43 AM FPGA Development: RE: UPP Sample Code needed
- For the FPGA interface, you could take a look at the "Vision Framework Design FIles":https://support.criticallink.com/redmine/projects/indio/wiki/Vision_Framework_Kit. This uses the UPP to push video data from the FPGA to the OMAP-L138. ...
- MW 07:39 AM Software Development: RE: DSP- EDMA Transmission problem
- Hello Mr. Krawczyk,
You can interface with the UPP directly as you have described and by looking through the TRM, or you can try to use the tcDspUpp.cpp class, which was intended to help a little with that but it certainly not require...

- RK 09:35 AM Software Development: RE: DSP- EDMA Transmission problem
- 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 Software Development: RE: DSP- EDMA Transmission problem
- To be more precise,
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 ...

- RK 05:20 AM Software Development: RE: DSP- EDMA Transmission problem
- Hello again,
I am writing because I have the following problem:
I succesfully transfer the data, but the transfer time seems to take too much time. I am transferring 4096 16-bit words using the modified FPGA EMIFA interface that takes ...

- RK 03:16 PM 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.
Best regards

- MW 09:57 AM Software Development: RE: GEL-file for MityDSP-L138F
- Yes. By default, the core should be 1.2V on power up.

- Hi,
that gel-file need to use for mitydsp-L138F with 1.2 V Core?
Thanks

- Thanks a lot Mike!
As usual, your support is impressive!
Ticket close.

- The model number for the part should be readable in the factory configuration information in the I2C prom. The model number includes a letter code for the FPGA type for the SOM. There is a factoryconfig utility program that can be run ...
- We have a product based on MityDSP-L138F using either LX16 and LX45 fpga cores.
Q1) Can we detect which FPGA core is running at runtime from Linux?
Q2) Is program_fpga.sh script and fpga_ctrl.ko module are able to handle both at ru...
