- FW 05:12 PM Software Development: RE: Mounting USB Flash Memory (mitydspl138)
- Hi Mike,
I don't think that is the case; I tried to manually mount as well, but there was no driver in /dev either. Greg sent me a new kernel with USB mass storage support built in, and that worked fine (although I don't recall if it ... - MC 10:33 AM Software Development: RE: Mounting USB Flash Memory (mitydspl138)
- Hi
I am also trying to get a USB disk to mount. Is it possible the USB drive is not auto mounted, but can be mounted manually? What would be the usb device name under /dev?
Thanks,
Mike - MW 11:16 AM Software Development: RE: SATA on MityDSP-L138F dev board
- Glad to hear it!
As for "who is in charge", the filesystem images (our "base" vs. our "full") are basically openembedded images (the "base" console image and an image that includes qt4-embedded libraries with a handful of utilities). ... - MC 10:27 AM Software Development: RE: SATA on MityDSP-L138F dev board
- Hi Mike,
Wow that was easy ;-) It worked right out of the box.
I am curious, who is in charge of the Linux distro that CriticalLink provides?
- SW 10:00 AM Software Development: RE: uPP/DMA registers
- Mike,
I was just planning on mapping the registers and accessing them that way. It looks like there is a specific method for setting the module PSC out of reset, but I assume just writing the correct pin mux value to the register wil... - MW 09:35 AM Software Development: RE: uPP/DMA registers
- Sure you can, though the pinmux setter/getter routines in the kernel are not currently exported.
-Mike
- SW 09:29 AM Software Development: RE: uPP/DMA registers
- Mike,
I see there is nothing in the da850.c file for the uPP, either for clock, or pin muxing. I could just write a kernel module to access the pin mux and PSC registers directly if I don't want to mess with recompiling the whole ker...

Kind of spooky the amount of time git.kernel.org has been down..... hopefully it will be back shortly....
-Mike
- MW 08:28 PM Software Development: RE: uPP/DMA registers
- check arch/arm/mach-davinci/da850.c
There is likely a clock that needs to be defined/enabled for the UPP.
Also there is a power and sleep controller register that may need to be enabled (part of the same clock structures in linux, ... - SW 01:43 PM Software Development: RE: uPP/DMA registers
- Mike,
Where is the clock tree? I think I have printed out the uPP status and control register, and if what I'm looking at is correct it is partially enabled, only the local reset is asserted. Scott - MW 08:23 PM Software Development: RE: Official u-boot with higher baud rate options
- Hi Noman,
I don't see any reason not to support this, but it may take some time for this change to propagate to our factory images/procedures. we'll need to test it here as well, but we'll try to roll it in. Thanks for the feedback.... - Hi,
I would like to get the following change in the next official uboot release. This would allow the use to change the baudrate at the u-Boot and transfer the images at higher baud rate, once the image transfer is complete the baudra... - MW 08:20 PM Software Development: RE: SATA on MityDSP-L138F dev board
- Well Mike,
I think all you need to do is get a powered SATA drive and plug it in. If you are using our provided filesystem (well, really just udev) and the default kernel you should have SATA support. The config option should be:
... - Hi,
I am looking to get some relatively quick proof of concept & testing of the SATA functionality with the MityDSP-L138F module and dev board.
Could you possibly point me to some resources on how to get a SATA drive running with e... - GG 10:52 AM FPGA Development: RE: ucf file
- Hi Scott,
Yes, you should be able to use the same UCF file. The pin mapping between the LX45 and LX16 is the same, the only issue is that there are 7 or 8 pins on the LX16 that are not connected on the LX45. If you try to use these pi... - We have a MityDSP L138 development kit with the Spartan 6 LX16 FPGA. We are in the process of purchasing the MityDSP L138 with the Spartan 6 LX45 PFGAs. Do we use the same ucf file for both fpga's found in the MDK release? That would ...

build-essential is now installed. However, i realized that the checkout was not done because it was not in the right directory. I corrected the steps as below:

- Hi Norman,
A couple of observations:
1) The package name is "build-essential" not "build-essentials", I will try to correct the original wiki page. Sorry about that.
2) When you cloned the openembedded setup, did you check out... - MW 07:25 AM Software Development: RE: ymodem

We've never tried using ymodem here at Critical Link as serial download speed hasn't been an issue. Folks generally have a faster interface to the device or do it during kernel runtime, or use kermit, which we haven'...

- Hi,
What is a better option to upload a file (uImage for example) at U-boot prompt ?
When ymodem transfer fails, u-boot stays in loop forever, unable to interrupt.
kermit seems slower than ymodem.
Are there any known problems usin... - Hi Mike,
I was trying to build the root file system using the instructions on the wiki but getting lot of errors. Could you please take a look at the attached file and let me know if i am missing something.

Glad you are up and running. Good point about the out of box experience.
Thanks,

That was it! I did not use the cable supplied because I always have serial cables connected to my computer.
On that note, the DVD should really have a simple getting started pdf explaining things such as the null modem ca... - GG 04:20 PM Software Development: RE: no serial data when first using dev kit
- Hi Mike,
J502 is the default RS232 port and the ribbon cable is meant to be used on this port for RS232 communication.
My guess is that you are not using a Null Modem cable and that is the reason you see nothing over RS232. Let us ... - Hi,

The files it was getting stuck on were ads7843.vhd, i2c.vhd, lcd_ctlr.vhd and tfp410.vhd.

From linux, if you issue the "reboot" command, it will jump back to u-Boot.

sorry to bother you - one last question. I noticed that after kernel installation using the uImage I built, the modules are missing. How can I make sure the drivers (.ko) files get into ... - GG 11:42 AM Software Development: RE: Transfer files to card from PC via usb ? instead of ethernet ?
