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 ... Jonathan Cormier

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, ... Ben Atkinson

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 ... Bob Duke

BA 04:25 PM MityDSP-L138 (ARM9 Based Platforms) Software Development: gcc 4.8 for OMAP-L138

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... Ben Atkinson

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... Jonathan Cormier

After transferring some files to the target flash (about 15 MB worth, overwriting old files), a short time later I encountered the following. I'm now wondering if there are some holes in the jffs2 drivers in use case areas that do not ge... Fred Weiser

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... Fred Weiser

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. Mathew Jones
