Mike,
thank you. You solved my problem. With the float option the dsp doesn't stuck.
Thank you Dominique Lytwyn

Hi Mike, good suggestion.
We are using the LX45 FPGA (The Industrial IO board is identified as 80-000268RI-2 Rev B and on the MityDSP SOM the Xilinx Spartan 6 FPGA is XC6SLX45)
From the MityDSP_MDK_release_2014-01-13 archive I've tri... Mathew Jones

Make sure that your FPGA bitstream generation options float the unused IOB's. By default they are pulled down. If you don't have active assignments for stuff like the watchdog reset control, the NMI, the EMIFA bus hold signals, etc., y... Michael Williamson

I have the MityDSP-PRO Board.

The done light is important. Sounds like the FPGA image is not correct for the board you are using. Are you using an LX16 or LX45 variant?
You can also check the programmed status by looking at the /sys/devices/fpga_ctrl/status file... Michael Williamson

Mike
Thanks. I have been referring to the document you suggested and some others on the CriticalLink site.
We do have the Rev B Industrial IO card (80-000268RI-2 Rev B) but I tried your "i2cset -y 1" suggestion and I don't get the er... Mathew Jones

Hi, I have so far failed to get our MitDSP-L138F to output to a monitor via the DVI link.
It's a similar problem to the LCD Framebuffer post ([[https://support.criticallink.com/redmine/boards/10/topics/4558]]), but which requires a diff... Mathew Jones

The attached script we made to automate building a project with code composer. I believe we did end up installing some X11 libraries on our headless servers in order for it to work.

MW 07:10 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: LCD Framebuffer Problem

Hello,
You may need to enable the backlight / LCD with the fpga_lcdctlr driver.
There should be a sysfs entry for the backlight with controls for enabling the LCD (powering it on).
I don't have hardware at the moment, when someo... Michael Williamson

Ben,
We are currently working on a unified VM release for our MitySOM-335x and MityDSP-L138 product lines (using a toolchain and filesystem that is Yocto compatible).
I expect that we'll have it released in 2-4 weeks.
