- EB 05:17 PM FPGA Development: RE: OFFSET constraint never passes timing
- I tried:
-shreg_extract = checked
-shreg_min_size = 5
No difference.
There is a DCM on i_ema_clk already.
Should there be a phase shift?
I sent you my project by email.
Let me know if you don't get it.
Our email is not workin... - MW 04:28 PM FPGA Development: RE: OFFSET constraint never passes timing
- If you have it disabled, then it won't happen. Try leaving it enabled and seeting min size to 5.
The other thing that could be done is to use a DCM on the EMIFA clock, which will allow you to deskew any delays in the clock routing.
... - EB 11:55 AM FPGA Development: RE: OFFSET constraint never passes timing
- Thanks Mike,
In Synthesis Properties, HDL Options, I have:
-shreg_extract = unchecked
-shreg_min_size = 3
I see that IOB FFs are being used (unless the signal was trimmed).
I also see that output and io pins are set to slow slew, ... - MW 10:46 AM FPGA Development: RE: OFFSET constraint never passes timing
- Sorry about the -3 vs -2 issue. We will correct that on our next release. However, several designs have been validated and close using -2 speedgrade (you should be able to confirm that with the reference project, I think) using ISE 13....
- EB 09:56 AM FPGA Development: RE: OFFSET constraint never passes timing
- The paths that are failing are from the pads to the EMIF module, I don't have any code connecting there.
Also, the Industrial I/O project that I started with selected a -3 device.
You're shipping with -2 devices, so I changed to that...

- MW 01:55 PM FPGA Development: RE: OFFSET constraint never passes timing
- Hi,
Two things.
1) You don't need the OFFSET=OUT spec with our IP. It turns out there is an extra clock in the wait states for read cycles, so you really have 18 ns to get the data to the OMAP, not 8.
2) Check this "FPGA overvi... - TI 01:38 PM Software Development: RE: SATA mount point
- You can also run "udevadm monitor" to watch for udev activity.
- JC 01:29 PM Software Development: RE: SATA mount point
- Scott,
I'm not sure whats going on. I can't explain why one would work as expected and the other doesn't. Its possible that udev is mounting sda to /media/sda. Trying running a 'grep -r /media/sda /' to see if you can find the file... - SW 11:44 AM Software Development: RE: SATA mount point
- the mmc card does not affect the mounting. It behaves the same way with or without it. I don't know if there are any differences with the dev kits. They were all purchased around the same time. I have reflashed them with a new kernel ...
- JC 11:39 AM Software Development: RE: SATA mount point
- Just as a curiousity, have you tried to see if adding/removing the mmc card affects how the sata drive mounts. Its the only thing I noticed different between the files you posted.
Are there any other differences between the dev kits ... - SW 11:35 AM Software Development: RE: SATA mount point
- i am uploading 4 files both my /etc/fstab and the output of fdisk. This is from 2 different systems with different SATA drives on. thanks
- JC 11:24 AM Software Development: RE: SATA mount point
- Scott,
Could you attach your fstab for both machines as well as the output of 'fdisk -l'?
-Jonathan - _Hello,
I've got a few mityDSP developement kits and am attaching SATA SSD drives to them. They are formated EXT4 with 1 Partition. I have modified /etc/fstab to attempt to automount the drive to /media/sda1 and have created the /medi...

- I am using the following timing constraints.
If I remember correctly, I started from the industrial I/O example and these were there.
NET "i_ema_clk" TNM_NET = "i_ema_clk";
TIMESPEC "TS_ema_clk" = PERIOD "i_ema_clk" 10 ns HIGH 50 %;...

- LM 06:31 PM Software Development: RE: USB on the go speed
- Hi Mike,
It would be great if I can get a copy of your sample code! It would help tremendously if I can get close to 10MB/s transfer rates.
Thanks,
Lars - MW 05:03 PM Software Development: RE: USB on the go speed
- Hi Lars,
We have found that RNDIS has been very slow as well and we have not used the serial gadget, but I would suggest that using larger packet sizes will help. We have used the gadgetfs driver with a camera product here and were a... - Hi,
When I configure Linux (3.2.0+) to use the ethernet gadget with RNDIS support, I get poor data transfer speeds. With data packet sizes aligned to the Ethernet packet size, we typically find speeds in the order of 0.6MB/s. That is pe...

- Mary,
Thanks for the update. I have created a task to enable SATA by default for the next MDK release. It was set in the old 2.6 kernel but was missed in the 3.2 update. - MF 09:24 AM Software Development: RE: SATA not recognized
- I got it working.
I compared myconfig to the .config file in the MDK_2012-08-10 linux-davinci directory and they were the same. I was able to follow the directions for building a kernel in your wiki page. (Except that I built it fro...

- MW 01:57 PM Software Development: RE: SATA not recognized
- I don't think you will need to rebuild DSPLINK or CMEM.
You should be able to take the myconfig and copy it to the .config.
In theory you could edit the myconfig, but generally it's better at that point to run menuconfig and select... - MF 01:36 PM Software Development: RE: SATA not recognized
- What's the best way to do that and change only that one feature?
I generated a config file from my kernel with the following command:
zcat config.gz > ~/myconfig
(See attached file)
Can this file be edited to make the required... - MW 11:54 AM Software Development: RE: SATA not recognized
- You need SATA_AHCI_PLATFORM set. You will need to rebuild the kernel.
-Mike
- MF 11:42 AM Software Development: RE: SATA not recognized
- Here's the result:
- JC 11:36 AM Software Development: RE: SATA not recognized
- Mary,
You can print the kernel config file by running:
_zcat /proc/config.gz _
You can then search the output:
_zcat /proc/config.gz | grep SATA_

- My colleague has another SATA drive and MityDSP board. He reports as follows:
"The drive comes up fine in Windows with the USB-SATA bridge, but no sign of it on the Mity DSP. We located an old, working SATA 1 drive and that one didn... - JC 10:51 AM Software Development: RE: SATA not recognized
- Mary,
There should be no reason that the drive isn't detected by Windows XP when using a USB to Sata adapter. Assuming you know the adapter works with other drives, it is possible the drive is bad. - MF 09:20 AM Software Development: RE: SATA not recognized
- I have tried the same SATA drive on a second MityDSP board as well as an older SATA drive. There are no "ata" messages in the boot log.
Could someone please respond?

thanks for fast reply!
The best would be an example using an fpga gpio pin and an omap pin, just to test the possibilities.

- Are you trying to use a FPGA GPIO or an OMAP-L138 GPIO?
The DspGpio.h class should provide access to the OMAP-L138 GPIOs from the DSP. The DspFpgaGpio.h class should be used to access FPGA based GPIO modules. Both classes are derive... - Hello all,
I need to hook a HWI to a GPIO pin in a DSP application.
I have some questions:
1- Do your core library provide any class to do that? I see DspFpgaGpio.h and Gpio.h, but they lack a bit of documentation, and I can't find ... - FT 12:49 PM Software Development: RE: L138 - DSP Timer interrupt question ...

Can you add more details regarding this statement: _The DSP loop optimization can create large interrupt latency as well (which can cause missed interrupts on things like large memory copies by the CPU, etc)._

Thank you so much for supporting.
For (1): At the first time. Now the board are running with null modem cable that is provided with the kit.

For (1) the console UART, please ensure you are using the serial cable provided with the kit (I believe the board requires a null modem cable connection).
For (2), when you s... - CR 08:27 AM PCB Development: RE: Resistors in EMA signal and adress traces?

it's the L138-FX-225-RC Module. No FPGA.
I'm concerned about both kinds of traces.
Christian - MW 07:33 AM PCB Development: RE: Resistors in EMA signal and adress traces?
- Which part number? Specifically, does the module include an FPGA or not?
Which EMA traces are you concerned with, data lines, control, or both?
I do not believe there are any inline series resistors on the data or address lines.
... - Hi,
can anybody tell me if there are already resistors on the EMA-traces on the L138-Modul integrated? If yes, what are the values of them?
thanks,
