- MW 12:43 PM Software Development: RE: DVI Framebuffer (fpga i2c) problem
- Hi Mathew,
Very sorry about that. I didn't catch the LX45 version. The LX45 has some pins that are not bonded to the FPGA package causing the limitation on our devkit (originally designed for the LX16).
Are you using a widescree... - MJ 11:26 AM Software Development: RE: DVI Framebuffer (fpga i2c) problem
- From our investigation and suggestions from other wiki/forum pages it is apparent now that it is not possible to output to a DVI monitor from a MityDSP-L138 + Industrial IO development board, with the LX45 FPGA. We have since purchased t...
- GG 11:35 AM FPGA Development: RE: Linux application cannot read/write FPGA registers
- Hi Matthew,
First we need to deal with the issue of /dev/0 not being present. Using /dev/mem is ultimately not what you want to do as you will run into caching issues.
/dev/0 is created after the FPGA is loaded and the device driv... - I am trying write a simple C application (for Linux on the MityDSP-L138 ARM) that can access registers within an LX16 FPGA image, which is yet to be implemented but I'd like to get the basics working for now with any of the CriticalLink ...

- Also, please make sure you perform the extraction as the root user:
- JC 03:51 PM Software Development: RE: gcc 4.8 for OMAP-L138
- Yes, extract the tar ball onto the root filesystem, but make sure to erase the existing one first. And backup your important files of course.
Please let us know if there are any tools missing from the new filesystem that you used in ... - BA 03:23 PM Software Development: RE: gcc 4.8 for OMAP-L138
- Bob,
Thank you for the response regarding the new gcc cross-compiler for the MityDSP-L138. Now that we're back from the holidays, I was able to successfully cross compile our application on my build machine.
I'm a little unclear, ...

- BD 04:58 PM 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 Software Development: RE: NAND Flash garbage collector and performance issues

- FW 02:22 PM 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...
