MDK_2013-05-15 Released

Added by Michael Williamson over 6 years ago

We've released a new board support package (MityDSP Development Kit, MDK).

Highlights (see the release notes in the installer for details):

- On the ARM/linux end, the mityomap-full filesystem image was trimmed back to <96 M by removing the Qt documentation and examples. This allows for fitting the filesystem within a 128 MB NAND partition.

- On the DSP end, several additional drivers were added to the core library.

- On the FPGA, a couple of new cores were added to support the ADS8329 and some misc SPI devices.

Account Registration Policy Changed

Added by Michael Williamson about 7 years ago

The Critical Link Redmine site has changed it's user account registration policy. You will no longer be able to auto-confirm new accounts via email. Instead, when a new account is registered, an administrator for the site will need to validate your account prior to being enabled. We are sorry for the inconvenience.

MDK_2012-03-12 Released.

Added by Michael Williamson over 7 years ago

We've released a new board support package (MityDSP Development Kit, MDK).

This package was built using a new toolchain (gcc 4.5.1) and eglibc. There is a new toolchain download that can sit side-by-side with the current toolchain. To install it on a linux machine you need to untar it at the root directory. To use the toolchain you'll need to execute:

user@machine: . /usr/local/oecore-i686/environment-setup-armv5te-angstrom-linux-gnueabi

The kernel released is version 3.2. This includes several new features and capabilities over the older 2.36 kernel, most notably some fixes and enhancements to the USB drivers as well as the ethernet drivers.

The angstrom distribution for the included filesystems is now using the OE core build process, and is based on the 2011 distribution configuration. Most notably the file systems use systemd over sysvinit scripts, which reduces the boot time a fair amount. Note: you should be able to generate your own file systems using The Online Narcissus Builder. The key is to select da850-omapl138-evm or the hawkboard configuration to start from. This will select binaries optimized for the OMAP-L138 CPU), and will also install the TI gstreamer code, etc. You will of course need to configure the boot to use the kernel port for your board. In additional, you may need to modify the inittab scripts to ensure that gettys are called with the "-L" option.

Next Release : New Kernel, New Toolchain + Filesystem

Added by Michael Williamson almost 8 years ago

This is a heads up that the next MDK release (scheduled to come out sometime around 2/12) will be a notable departure from the earlier releases in the following ways:

  • New Kernel - the next release will advance the Linux Kernel to version 3.1 (or potenrially 3.2) from 2.6.34-rc1 and will sync back up to the linux mainline. Several new features and performance improvements for the OMAP-L138 SOC have been incorporated into this Kernel
  • New Toolchain - the next release will be built using GCC 4.4.3 and eglibc (instead of glibc).
  • New Angstrom Distribution - the angstrom build is being advanced from the classing OE to the new OE Core infrastructure supporting the recent 2012.1 Distribution. Faster boot time, updated tools, etc. Details about reproducing the filesystem will be coming shortly.

Critical Link will likely not advise current customer to upgrade to the new release unless they have a specific need for the upgrade, as some of the custom board files will not have been advanced to the new kernel by the release date.

New customers (or new designs) should start with this release if at all possible for smoother long term support.

Audio Support Added for Rev-C Industrial I/O Boards.

Added by Michael Williamson about 9 years ago

We've added basic support for stereo line-out audio for the Industrial I/O board to the local kernel. You can download the changes in our local kernel git repository. Binary releases, for upgrades, will be posted soon, or you can build it from source.

The audio support uses the ALSA framework/API. The supported sample rate is 48000 Hz stereo at line out levels. Codec mixing and gain control is not available.

Testing has been performed using the aplay utility, as well as the gstreamer utility with an alsasink pipe endpoint.

U-Boot Updated to Support MMC.

Added by Michael Williamson about 9 years ago

The folks at TI recently updated u-Boot to support reading / accessing / booting from MMC devices on MMC 0.

We've rolled their code into the the MityDSP-L138 / MityARM-1808 u-Boot. Available in the u-Boot git repository. Binary releases, for upgrades, will be posted soon, or you can build it from source.

Performing FLASH upgrades and Booting off of MMC devices connected to MMC 0 of the OMAP-L138 port is now possible.

Website installed

Working to populate documentation. Please post if you need content ASAP, we'll put that to the top of the list.
