- MW 12:50 PM Software Development: RE: use of stl vector class on DSP side of OMAP-L138
- 6.1.9 is *really* old, Rich. Last time I checked, we are using at least 6.1.19 here. You might consider checking the release notes on the newer builds and see if any STL stuff is mentioned. I believe STL was "new" feature in 6.1.

- Hi Mike,
At the moment I'm using the 6.1.9 toolchain hosted on the PC side through CC v3.3
I'm primarily vectoring intrinsic types but there are a few places where I'm
vectoring something like:
vector< complex<float> >Foo(Some... - MW 12:03 PM Software Development: RE: use of stl vector class on DSP side of OMAP-L138
- Hi Richard,
What version of the code gen tools are you using? If it's an older chain, TI may have already found/fixed it. You might cross post this on "TI's E2E Site":http://e2e.ti.com as well.
We have used the std::vector clas...
Has anyone used the standard template library vector class on the DSP side of the OMAP-L138?
I have a large memory intensive algorithm that is being adapted from a corresponding MATLAB
program and up til now have been using STL vec...

- AH 10:11 AM Software Development: RE: DSPLink kernel driver
- Hi,
I have just rebuilt the kernel module, and I have just spotted that the build issues a warning:
Building kernel side code using kbuild
make PROFILE=RELEASE -C /home/mitydsp/MDK_current/sw/ARM/linux/linux-davinci SUBDIRS=/home... - MW 08:33 AM Software Development: RE: DSPLink kernel driver
- Hmm...
Are you using the same build of the kernel (e.g., the same .config file) as the one that is running?
Did you use the same toolchain for both builds?
I haven't seen this particular issue. Can you post your .config file th... - Hi,
I have built dsplinkk.ko using the instructions on the wiki. Modinfo reports:

- Hi,
That did it !
I now have a working kernel, that I have built. Onward now to getting the DSP stuff to work :)
Many thanks,

- MW 11:23 AM Software Development: RE: L138 UART and DSP
- Hi Andrew,
With the MityDSP-L138F, you have two options for UARTs: you can use one of the three UARTS provided on the OMAP-L138 processor, or you can use one or more UART cores (made available by Critical Link) instantiated in the FP... - Hi,
For the project that I am currently engaged in we have a remote ADC device that feeds data down a fibre optic link into a UART.
I want the UART to be read by the DSP which will then perform a variety of manipulations and calc... - MW 10:14 AM Software Development: RE: Kernel Hang
- Note the change to the _defconfig file, BTW. (industrialio_defconfig, not mityomapl138_defconfig).
- MW 10:02 AM Software Development: RE: Kernel Hang
- Ok,
Sorry guys. I need to update the instructions on that page. The devel branch is no longer maintained, and you should always reference new work off of the master. The proper instructions, for the Industrial I/O board, should be ... - AH 10:02 AM Software Development: RE: Kernel Hang
- Hi,
I built the kernel as per the instructions here: http://support.criticallink.com/redmine/projects/arm9-platforms/wiki/Linux_Kernel
I have made no local changes, I can't get the vanilla one to work :)

Andrew provided this information to me prior to posting on the forum:

- Hi Andrew,
Can you please identify where you got the kernel (is it from support.criticallink.com, arago, the TI PSP, or mainline?) and what commit point you are working with? You might also want to include the .config file so that we ... - Hi,
I have a MityDSPL138 in the industrial IO board. I have built a new kernel, (2.6.34-rc1) It hangs when I try to boot.
I can boot the board from another copy of the kernel, both from flash & by tftp
Here are the u-boot set...

- Mike,
The new boards boot with the 2011-08-01 uImage. I still need to check if this image is backwards compatible with the older MityDSP boards.
Thanks,
Dave

- MW 11:16 AM Software Development: RE: Kernel Hang Anomaly
- Hi Dave,
I think you might want to use the uImage located in the release_2011-08-01.run file under MDK_2011-08-01/images/uImage. There are several bug fixes from the May 2010 release that may be causing the hang.
If that doesn't h...

- Hi Dave,
Can you please post the complete text of the boot attempt, from the start of power up to the hang?
Also, can you please type "factoryconfig" as well as "config" and dump the results from u-Boot?
Thanks.

I'll let the technical team address the hang. But just wanted to let you know that modules are shipped without a kernel or file system installed. This is a customer configuration step since our customers run a variety of o... - We recently received MityDSP boards containing u-boot but don't have Linux installed. Note that MityDSP product configuration varies since Linux was installed in previous shipments. I attempted to install the following components on se...
