- BD 04:58 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: gcc 4.8 for OMAP-L138
- Ben,
We are in the process of testing a Yocto-compatible toolchain for the MityDSP-L138 family. This release includes gcc 4.8.
I have uploaded an ALPHA version of the new MDK to this website under the "Files" tab. It includes a ... - Our group has a strong desire to use gcc 4.8 to compile for the ARM926EJ-S on the OMAP-L138. We want to take advantage of C++11 thread support that is in 4.8. The arm-angstrom-linux-gnueabi-gcc we have been using is gcc 4.5.4, and it h...

This is quite possible if you are writing a lot of data onto the nand. If you have no need for the 2nd partition you could reduce fragmentation by removing the 2nd partition and expandin... - FW 02:33 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: NAND Flash garbage collector and performance issues

- FW 02:22 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: NAND Flash garbage collector and performance issues
- Answering questions:
The jffs2 flash is divided into 2 partitions of which I'm using only one; I have just over half the space within that partition used (51% according to the df command).
I have run some tests to determine where t...

- MJ 05:36 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DVI Framebuffer (fpga i2c) problem
- Quick update:
I just downloaded the FPGA binary from the similar LCD forum post [[https://support.criticallink.com/redmine/boards/10/topics/4558]]
and this programmed OK ("Done" LED lit and the status returned was PROGRAMMED)
Lookin... - MJ 05:21 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DVI Framebuffer (fpga i2c) problem
- Hi
Still no joy in trying to get DVI output working via the FPGA.
The "Done" LED never lights for any of the FPGA binaries.
The fpga_ctrl.ko driver I'm using is from the MDK_2014-01-13 as are the FPGA binaries.

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... - DL 08:50 AM MityDSP (TI TMS320C6xxx Based Products) FPGA Development: RE: Programm FPGA via JTAG
- Mike,
thank you. You solved my problem. With the float option the dsp doesn't stuck.
Thank you - MJ 03:19 AM MityDSP-L138 (ARM9 Based Platforms) 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...

- MW 11:14 AM MityDSP (TI TMS320C6xxx Based Products) FPGA Development: RE: Programm FPGA via JTAG
- 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...
- I have the MityDSP-PRO Board.
Whenever I program the FPGA via JTAG and then want to debug the DSP via JTAG I got an error: " Trouble Reading Memory Block at 0x80514c"...
When I try again to debug the DSP I got an error: "Error conn... - MW 11:12 AM MityDSP-L138 (ARM9 Based Platforms) 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... - MJ 10:41 AM MityDSP-L138 (ARM9 Based Platforms) Software Development: RE: DVI Framebuffer (fpga i2c) problem

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... - MW 07:49 AM MityDSP-L138 (ARM9 Based Platforms) 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... - 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...
