AB 03:11 PM Software Development: RE: LCD Framebuffer Problem: Se-Sang,
Please download the following .zip file (https://www.dropbox.com/s/hf8l6wqtxa72a04/lcd_xilinx_13_2-2-1-13.zip?dl=0) which contains source code as well as a pre-built LX45 binary image that supports the LCD display for the L13... Alexander Block
MJ 03:19 AM Software Development: RE: DVI Framebuffer (fpga i2c) problem: 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

MW 11:12 AM Software Development: RE: DVI Framebuffer (fpga i2c) problem: 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
MJ 10:41 AM Software Development: RE: DVI Framebuffer (fpga i2c) problem: 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
MW 07:49 AM Software Development: RE: DVI Framebuffer (fpga i2c) problem: Hmmm.
Take a quick look at this "wiki page":https://support.criticallink.com/redmine/projects/arm9-platforms/wiki/LCD_configuration if you haven't already.
The i2c commands you are running are for the Rev A & B boards, which are ve... Michael Williamson
MJ 03:34 AM Software Development: DVI Framebuffer (fpga i2c) problem: 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

JC 09:35 AM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS: 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.

BA 01:32 PM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS: Brandon,
Thank you very much for the reply. I tried what you suggested with the prerequisites and the "--mode console" on the EDMA3 installer, and the installation appeared to work.
The Ubuntu desktop revealed that the ccs_setup_.... Ben Atkinson
BM 10:52 AM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS: Hi Ben,
I have not tried CCS 5.5.0, but the EDMA installer accepts a "--mode console" argument that can be used to run the installer in text mode. Try running the CCSv5 installer with the "--help" option to see available parameters fo... Brandon McDonnell
BA 09:16 AM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS: Here's another wrinkle...
I successfully created a VM for building our OMAP L138 application in a Ubuntu 14.04 LTS desktop environment. However, we have a requirement to use Continuous Integration for nightly builds and testing on a ... Ben Atkinson

SM 09:44 PM Software Development: RE: LCD Framebuffer Problem: The P/N of the Dev Kit for L138-FI-236-RL is 80-000382 and the P/N of LCD is 80-000536. Se-Sang Mun
SM 09:40 PM Software Development: RE: LCD Framebuffer Problem: Hi, Mike
I am using with Dev Kit for L138-FI-236-RL(80-000382) and 4.3In WQVGA LCD(80-000536).
I had to set the LCD Panel to NEC NL4827HC19-05B in the u-boot.
Can you explain in detail for eabling the backlight/LCD??
And, I wou... Se-Sang Mun
MW 07:10 AM 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
SM 04:40 AM Software Development: RE: LCD Framebuffer Problem: After rebuiling the kernel (kernelversion 3.2.0) with gcc version 4.5.4, I had to re-download the kenel.
I made the bin file of FPGA(XC6SLX45) based on the contents of the sites below.

JC 08:42 AM Software Development: RE: LCD Framebuffer Problem: What kernel are you using? Which defconfig? The lcd configuration is done in the file arch/arm/mach-davinci/baseboard-industrialio.c function baseboard_setup_lcd(). You may want to place some print statements in there to make sure the ...

SM 10:52 PM Software Development: LCD Framebuffer Problem: Hi,
I am being tested with Dev Kit for L138-FI-236-RL(MityDSP-L138F) and 4.3In WQVGA LCD.
The version of the L138-FI-236-RL is expected to be C.("14-08-06 C" on the sticker on the back of the board is shown.)
I tried to follow the... Se-Sang Mun

BD 04:45 PM Software Development: RE: OMAP L138 Cross-Compiling on Ubuntu 14.04 LTS: 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.
